Best explanation of the PW 100 motor and its parts

The engines of the PW 100 series are leading in modern, ultra-modern regional and commuter turboprop engines. With its three-coil design, easy-to-maintain modular structure, and high power rating, the engine is a logical choice for medium to large turboprops, including the Bombardier Q400, DeHavilland Dash 8, and Embraer EMB 120. Some consider the PW 100 a replacement for the venerable PT6, but in reality the PW 100 picks up where the PT6 Large version left off in terms of performance, fuel consumption and reliability. The PW 100 series consists of a number of variations. There is no actual PW 100 motor. The motors start with the PW118 motor and end with the PW127J.

The engines are essentially the same, with mostly a steady increase in power output and minor fluctuations in engine power and the ratio of mechanical shaft power to generated thrust. In other words, each turboprop is rated in Equivalent Shaft Power (eshp), which is a combination of the actual mechanical power on the output shaft and the amount of power available that is available as the conversion of the thrust generated on the exhaust pipe. The proportion varies, but is typically in the range of 80% of the power produced by the propeller and 20% of the power produced by the exhaust pipe.

The powerful PW 100 motor is completely modular. That is, it consists of a number of interchangeable modules that can be easily removed and replaced if there is a problem with the engine. The modules consist of the turbomachine, the power turbine assembly, the inlet housing and the gearbox for power reduction. The compact turbo machine consists of the double-coil gas generator and the accessory gearbox. The power turbine is connected to the rear of the turbomachine and has a two-stage power turbine that drives a shaft that runs forward in the center of the turbomachine’s shafts. The inlet housing is attached to the front of the turbomachine and provides space for air to be drawn into the compressor and support for the gearbox to reduce power. The power reduction gearbox mounts to the front of the inlet housing and takes the high speed input from the turbine shaft and converts it to high torque, low speed power taken from the propeller flange on the front of the gearbox.

Atmospheric air is drawn through the engine nacelle behind the propeller into a passive particle separator that is part of the nacelle. Clean intake air is drawn up into the downward scrolling motor inlet. Air is sucked into the turbomachine by the single-stage radial compressor. The air is accelerated outwards by the compressor and fed into numerous curved diffuser channels, which distribute the air flow evenly over the surface of the single-stage centrifugal high-pressure compressor. The high pressure compressor increases the pressure on some later models to a design pressure ratio of nearly 15: 1. The high pressure compressor feeds the airflow to a diffuser which converts the dynamic pressure to static pressure as it enters the annular backflow combustion chamber. The compressed air enters the inner combustion liner where it is mixed with jet fuel and ignited. The resulting gas is expanded through the high pressure nozzle to meet the high pressure single stage axial turbine that powers the high pressure compressor and accessory gearbox. The gas is then further expanded through the low pressure nozzle to drive the low pressure turbine, which drives the low pressure compressor. Eventually, the gas is expanded through the two-stage power turbine to drive a concentric shaft to the front of the engine, which drives the gearbox to reduce power. The exhaust is then drawn out of the short, fixed section, axial flow exhaust outlet to provide nearly 2,000 lbs. Thrust on some popular models of the PW-100 engine. The gearbox for power reduction reduces the speed of the power turbine to a useful 1,200 or 1,300 rpm to drive a four-bladed propeller at a constant speed. Accessories include a generator, oil pumps, fuel pumps, hydraulic pumps, and a FADEC fuel controller.

The dual coil compressor offers many advantages over a similar single coil compressor. Since the two compressors can be operated at different speeds, the compressors can be optimized for a large number of air flows. This allows for a higher design pressure ratio, much better part performance efficiency, and very quick engine response. High pressure ratios and high turbine inlet temperatures allow very low specific fuel consumption, and advanced cooling techniques and state-of-the-art materials allow a long time between overhaul periods.

There are a few other variants of the PW 100 worth mentioning. The PW150 motor is a high-performance development of the PW 100; It is very similar in overall construction and dimensions to the PW 100, with the exception that the low pressure compressor is a single stage axial followed by a single stage centrifugal. The pressure ratio is greater than 18: 1, and the engine produces power in the 5000 horsepower class. This makes it a suitable replacement for the Allison T56 or an alternative to the Rolls Royce AE1107C. There are also turbo shaft versions of the PW 100 where the gearbox and inlet are removed to reduce power and replaced with a shielded inlet with bell mouth and a carrier bearing. The engine output is at turbine speed. The motor could be an alternative to the CT7 (T700) turbo shaft in medium-sized helicopters, although it has not previously been used in this application. However, there is a ship variant of this turbo wave for modern military surface effect ships. These models are called the ST18M. The power is around 3,200 hp.

The throttle control technology can accelerate the engine when more power is needed, helping the engine to last longer while achieving the maximum possible fuel efficiency.

The ETQ TG72K 8250 W Reviews:

The ratings for the gas-powered model ETQ 8250 Watt were very good with a rating of 4.7 out of 5 possible stars. Most reviewers agreed that this is excellent value for money with all of the features included and the amount of power it delivers.

Some people commented that they especially liked the idle control when charging batteries. Other reviewers liked the fact that there was a fuel gauge in addition to a built-in hour meter. Attaching the wheels and handle assembly was as easy as starting the unit. Most reported that it was first started on the second or third puff when pull start was used and the first time afterwards.

People have reported that this model worked just fine in emergencies during recalculation of disasters like hurricanes where they were without power for up to ten days. During this time, they just stopped the device by adding fuel, which ran continuously and perfectly during that time.

Some people reported that they did not like the location of the starter cord and wished it was in a different location, but it still worked fine for them. A few other people weren’t happy that the auto-start battery wasn’t included, but were able to find a battery at Wal-Mart for a nominal cost.

In short, this is a very well made unit and the vast majority of people are very satisfied with this model as a home generator or RV generator unit and would recommend this unit to others and we also recommend it to be a powerful one , well built, durable and versatile generator.


Top 3 Ways To Improve Your Golf Skills

Golfers are always looking for great ways to improve their skills. I’ve compiled a list of the top three ways to improve your golf skills without paying an instructor to help you.

Your elbow must touch your hip

One of the biggest mistakes most golfers make is keeping their elbows off their hips. It’s very easy to miss this step as it feels natural for your elbows to stick out to the side, but try to avoid this at all costs. Your elbow touching your hip keeps your racket nice and straight so you have more control when you hit the ball.

Let your golf club do its job

Most golfers think the harder you hit the ball, the further it will go. This is not necessarily true. It takes a precise swing right in the middle of the ball to go far. If you swing too hard and don’t hit the exact part of the club you need, the shot will be sliced ​​or turned into a fresh air shot. Take your time and make sure you hit the right point in the racket. Once you’ve mastered this, hit the ball with more force.

Hip rotation

Your whole body should move when you swing. Using only your upper body strength will not give you the full strength that you could get if you put your hips on the swing. As your swing goes down, your hips should follow the same movement. It’s almost like imitating the movement of the golf club. Your hips should swing at almost the same speed as the golf club. Watch the pros on TV when they swing. It’s almost like using their whole body to get the hit.

Stay fit

Swinging the golf club uses many muscles that are normally not used that often. Having a strict training regiment can help you improve your game. The better your core, back, legs, and arms fit, the better the chance you’ll hit the ball correctly every time and with consistency. Your muscles have memory and the more you use them, the more memory they retain.

Golf is a very challenging sport, but if you use the right techniques and preparation it will get easier over time.


How to put your table lamp back together

Have you ever had to pull apart your table lamp, perhaps to replace a globe or a damaged socket, only to find that you have no idea how to reassemble it? While they may look awfully complicated, these types of lamps are actually quite easy to put back together.

Step 1: Place the base on a flat work surface, followed by the body. The base often has a hole in the center for the power cord to run out of, while the body should have a hole on either end.

Step 2: Slide the rod into the top hole in the body, out there into the bottom hole, and into the base. Place a washer over the end of the rod and screw it in place. Then feed the string into the bottom of the pole and out through the top. Screw in the neck (if the table lamp has one) and the harp.

Step 3: Place the base cap over the bottom of the harp and screw it onto the pole to make sure it is the right way up. Wrap the “hot” wire around the gold screw on the base and the “neutral” wire around the silver screw.

Step 4: Place the base shell over the lamp socket, making sure to insert the cables into it. Squeeze the ends of the harp together and slide it into the bottom of the bowl. Then screw in a lightbulb.

When assembling your table lamp, note that depending on the type, additional or even fewer steps are required. If you’re stuck assembling your lamp, contact a lighting specialist or even the manufacturer for advice.


Heated Travel Blanket – Bring the comfort of an electric blanket to the road

A heated travel blanket is a 12 volt, low voltage travel blanket that you can store in an easily accessible place. These portable electric blankets are an easy way to create the cozy comfort of your home when traveling in your car or sleeping in a tent. Cold is one of the guaranteed ways to spoil a trip, whether the person feeling cold is yourself as a partner or a child.

The heated electric travel blanket gives you a luxurious blanket and soft warmth wherever you have a 12 volt plug, e.g. B. in cars, boats or mobile homes. Great for cold morning starts or long journeys, the heated blanket will keep you warm whether or not it’s plugged into its own rechargeable power supply.

Storing one or more items in your car as part of your emergency equipment is also great when you need a rug for an impromptu picnic, concert, or stadium rug.

This blanket is a must have for road trips, especially if you live in an area that gets very cold in winter or at night. They can be a lifesaver if the kids have to sleep in the back seat during a trip. A heated travel blanket can be used like a normal travel blanket. However, if more heat is needed, it will heat up completely in about 10 minutes. Heated travel rugs are designed in such a way that the heat is evenly distributed so that there are no unpleasant “cold spots”. They generally consist of two layers that help capture and hold body heat.

Men and women have argued for years about air conditioning in hotel rooms, cars, etc. Many women often feel much colder than men. So if you enjoy traveling, buy one for yourself or for the lady in your life. With the heated travel blanket, she can wrap herself in the blanket, plug it in and be warm while her husband has the temperature set to what is comfortable for him – a great win-win situation. This could of course also apply the other way round =)

As with most travel blankets, electric travel blankets must be selected based on your needs:

  • Size is a factor as always, usually a larger one will fit more needs, but if you know you will only be using it for your dogs in the back seat, a smaller one might be a better choice.
  • Cable length can be a factor. Make sure the cord is long enough to be used on the nearest 12 volt lighter socket. This is probably not a big problem as most cars have a 12V lighter socket in the back, and most blankets come with a 6-foot or longer power cord, which should generally be long enough to hold the blanket in the back seat use.
  • An optional feature that might be worth a look is a safety timer with an automatic shutdown and reset button.

Tips from a power washing consultant for getting started in the rail industry

In this troubled economy, it may come as a surprise to hear that washing railcars and locomotives under pressure is a lucrative market. Railway companies used to do the work in-house, now most companies outsource the work to a car wash company. According to Paul Horsley, a professional power laundry consultant and president of Scotts Pressure Wash in Calgary, Alberta, Canada, this is a market that pressure wash companies should seriously consider:

“The rail industry in North America is much bigger than most people think, and just like other modes of transport, railroad companies require power washing services,” says Horsley. Statistics from the Association of American Railroads show that Canada, Mexico, and the United States have more than 1.59 million freight cars and 24,143 locomotives in service. You can bet a good number of these railcars will travel through your state on any given day moves! “”

From removing graffiti from tankers to dry sweepers to degreasing locomotives, the industry has plenty of options for any car wash company willing to put in extra efforts to build a customer base and secure contracts.

While adding the rail industry to your service list might sound intimidating, most of what you know about pressure washers can be applied to railcars. With a little additional research and some advice from a pressure washing advisor, working on the railroad is a perfectly attainable and profitable goal.

Here are some things you need to know before you prepare a bid:

The type of railcar you need to clean. Ask your customer if there are any industry or company specific regulations that you should be aware of. For example, when washing locomotives, pressure washing the disc brakes can cause corrosion, resulting in brake failure. This is a significant safety risk, and the American Association of Railroads has written guidelines that require waterproof tarpaulins to cover the brakes before washing begins.

Place. Where is the job done? Who does the land belong to? Is there a source of water available? What are the environmental requirements and where is the wastewater disposed of? Wastewater recovery requires careful planning: trucking in the water, access to an elevator to work on railcars, ensuring that all pressure washers are functional and equipped with the appropriate chemicals, and most importantly, adequate safety equipment to protect workers from chemical overspray and risk of falling.

Timeline. Horsley expects the rail industry to have tight deadlines on contracts as they need to get their railcars back into service as soon as possible. It is not unusual to have to clean an entire unit train consisting of 125 multiple units in three days. Horsley also explains the importance of visiting the website in advance:

“Although I did my due diligence and visited the rural site in advance, I never thought about how different this site would be after a period of heavy rainfall. We only had a short window of time to complete the work and because of the rain We had great difficulty getting equipment in and out of the job site – to say it was a challenge to get the job done on time and on budget would be an understatement! I’ve since learned that having one is a good idea to allow additional day to be built into the construction site to take unforeseen circumstances into account. “

After you’ve spoken to a pressure washing advisor and set up a system, you’re ready to begin cleaning the railcars. The chemicals most commonly used in cleaning railcars are sulfuric acid, ammonium bifluoride and hydrofluoric acid. The cleaning takes place in six steps:

1) Clean roof: dry wash and rinse

2) Clean the sides and undercarriage

3) Start wastewater recovery at the same time

4) Remove graffiti that may require manual scrubbing

5) Apply degreaser if necessary

6) Flush the entire unit from top to bottom, including the wheels and undercarriage

7) Repeat. To repeat. To repeat.

Splint-related cleaning options include:

– Freight wagons (pressure wash outside. Dry cleaning / steam inside.)

– Tanker (external pressure wash and graffiti removal)

– Grain bin (manual removal of dirt on the end decks and pressure washing)

– Locomotives (external pressure wash with special consideration of the engine compartment)

“Once you’ve got a system in place, it’s quick and easy,” says Horsley, who is also a longtime member of High Pressure Washers of North America (PWNA). For more information on train cleaning, please contact your local power cleaning advisor first. You can also register for a two-day workshop at PWNA at


Ecotourism: Giving Back While Traveling, History of the Indian Church Development Project in Belize

A group of artists, architects, and archaeologists, partly motivated by the relentless efforts of K. Pierce, have volunteered to work with the residents of Indian Church Village Belize to help them set up a local handicraft workshop or home industry to produce high quality Mayan handicrafts that they can sell to tourists. Our efforts also include education-based programs, including a library and literacy workshops, as well as a scholarship program. We hope that this will ultimately provide an economic and educational basis for many of the people who live in this very rural village (a village that doesn’t even have electricity and whose school for students ends at the age of 13!).

Indian Church Village Artisans, Belize (ICVA)

In the summer of 2000, we received a small scholarship to teach the people of the Indian Church in Belize handicrafts and integrate the community into the archaeological site of Lamanai. We have been working on this craft training project ever since. Many art workshops have been held for the residents of Indian Church Village in recent years. We emphasize the art of the Maya, especially that at the Lamanai location, as well as the revival of the old handicraft traditions. There are currently four groups including metal smiths, potters, stonemasons and a sewing group.

A non-profit organization called the Indian Church Village Artisans (ICVA) was formed and registered with the Government of Belize. We received a grant from the UK High Commission to build a handicraft center in the village. The building was completed in 2003 and it is now important to continue to raise additional funds for tools and equipment, as well as funds for teaching additional classes. The project also secured funding through the efforts of K. Pierce of Rotary International and Belize’s Social Investment Fund (SIF), who provided a reliable solar power system, classes and supplies for the craftsmen.

Indian Church Village Library

The Indian Church Village Library in Belize opened in July 2004 and is open 4 days a week. It offers summer reading incentive programs, adult literacy classes, and a reliable place to study for students. Recent fundraisers secured the librarian an annual salary, built a 10 by 16 inch addition, and added shelves and other necessary furniture. It still needs financial and financial support. The librarian received training from Belize National Library Service (BNLS) workshops.

Indian Church Village Scholarship Program

There are approximately 9 students from Indian Church Village in Belize who have received a scholarship and are going to school after age 13 (which is the typical age to quit as there is no school nearby AND it is very expensive to continue their education). A Canadian non-profit organization called S.H.A.R.E. played a huge role in this, as did K. Pierce’s private fundraising drives. These students must be at least 1 hour (approximately 2 hours) away and stay in a safe home during the week to attend middle and high school. The cost of this is out of reach for many residents of this small, remote village.

Beyond Touring is an ecotourism company This partly financially supports the possibilities of ecological and cultural tourism and supports this project to improve the community.


A stock that is bigger than Amazon and Google combined

At the boarding school in India we waited eagerly for power outages.

Blackouts for us kids meant we could light our candles and play with wax. We lit pencils, erasers, or anything we could find.

We could also avoid doing our homework. Instead of working, we just played in the dark.

Power outages were so common that we knew how to go to mass in the dark for dinner. And then we made our way back to our dorms with no lights.

We got ready for bed with a couple of kerosene-powered lanterns.

In India at the time, electricity was as much a luxury as it was a necessity. We knew how to live with or without.

That was then. In India and around the world, electricity and general energy are a necessity today. Life stops when there is no energy.

In the United States, energy is the lifeblood of our economy. And we are currently experiencing a historic transition to a new form of energy.

This new form of energy will disrupt at least three main parts of our economy. And I believe it will make a huge fortune for those who invest in it.

New energy: a megatrend

I present the fourth megatrend. This megatrend is new energy.

New energy is energy that comes from natural sources.

Sources such as sun, wind, waves or geothermal energy.

The other thing about new energy is that it is storable and portable.

After all, the last thing about new energy is that it is local, which means that you get your energy from somewhere near you, like your home.

When you put it together it will mean a revolution in the way we live, work and travel.

There is one company leading the new energy revolution … and it will be bigger than Amazon and Google combined.

You see, this company has products that touch every aspect of new energy, from getting its energy from natural sources, to storing it so it can be generated locally, to portability so it can be used for travel.

With those aspects together, this company will disrupt three massive industries.

The essence of “disruptification”

These three industries are the utility industry, the energy industry and the transportation industry.

My estimate is that the companies in the industries that disrupt and potentially wipe this single company have a market value of more than $ 7 trillion. This company has the potential to increase its current value by ten times, or 1,000%.

You might think this way of thinking is insane and just hype.

However, I can tell you that few people in the early days believed that Amazon would single-handedly dominate retail.

Or that Google almost has a monopoly on text advertising.

Or that Netflix would be a global video streaming powerhouse.

The reason these companies were able to build these amazing domineering companies is because the technology they used could be applied to already large categories of companies.

In other words, they were simply taking customers away from companies that were using old, outdated, outdated technology and business methods.

This is the essence of the “disorder” where the old way of doing things is replaced with new ones … in a short time.

Like what Netflix, Amazon, and Google did

Right now, the energy, utilities, and transportation industries are going through what Netflix, Amazon, and Google did for their various industries a few years ago.

The old will be obliterated and the new will take its place.

This is an exceptional opportunity to make massive profits when you are ready to get involved in the new ventures.

As you can imagine, I can’t give away the stock.

However, I’ll say that investors are going to lose an incredible amount of money buying stocks of old companies with old, outdated, outdated technology. Sooner than later, these companies will be wiped out and their stocks will go to zero.


Strong papillary light reflex in infants associated with a later diagnosis of autism

How many of you like to travel? As humans, almost all of us have a desire to travel, visit previously unknown places, explore uncharted territory (although, quite frankly, there aren’t many places that can claim to be uncharted territory in this century). Now the point is whether we all or each of us, regardless of our love of travel, actually enjoy traveling and the benefits associated with it like getting to know new places, learning a new culture, etc., unless we had the strength of seeing, right?

Importance of the eyes

I mean, how could we gasp at the sight of the now extinct Fiji volcano, or how could we enjoy the lush greenery of the Canadian forests or say, how could we see the almost dreamlike Taj Mahal on a moonlit night, or how could we see love that our parents had or still have for us if we didn’t have this God-given vision?

Medical conditions related to the eye

Under these circumstances we realize the importance of our eyes, because being eyes lives in the 21st century with any light that exists in primeval darkness without light or illumination. And since the subject of darkness was brought up, why not talk about how sad or depressed or irritated we feel when load shedding occurs? It is in these moments that we realize, even if only for a short time, what it means to be blind or without eyesight. Now, of course, do the eyes have their own diseases or diseases that affect them too?

Read on to learn more about such a disease or medical condition of the eyes that is common around the world.


Autism is or can be defined as a disease or medical condition that leads to social awkwardness and repetition of thoughts or behaviors or patterns in the same.

Papillary reactions

Scientific studies have shown that infants or older children with autism tend to be more sensitive to light, meaning that they exhibit a strong papillary light reflex when exposed to it. When more studies were done, they showed that infants were more likely to be diagnosed with autism than the general population because they exhibited this strong papillary response more strongly than the general adult population.

What are papillary reactions?

Papillary responses can be defined as responses of the nerves of the eyes when exposed to a particular optical environment or an environment containing different degrees or types of light. The reactions can be extreme or normal or below average.


Autism can therefore be said to be a disease or medical deficiency that leads to social awkwardness and repetition of thoughts and behavior, and one of its most visible symptoms in relation to the eyes is the strong papillary reaction or hypersensitivity to light.


Power golf swing requires more accuracy than a weak one

Many golfers come to me to increase the power of their golf swings, as I do. They’re usually surprised that I start their training with the basics by starting with the short game shots and using the sand wedge.

To have an extremely powerful golf swing, a fundamentally solid swing is essential. All the levers on the body that control the club’s face and the direction of the club heads must be trained to slowly control the club. This is so that when we are vibrating very strongly, the control factors have all been programmed into our swing and practiced perfectly.

Since the release actions I have taught are generally at odds with the release most players have learned, I find that learning to use the ingredients while practicing the short game shots creates total control when making the fuller and harder swings do. It is also much easier to learn these actions when performed slowly and with great precision.

To understand this better, think about how one would learn a complex piano piece. The pattern would be learned first and later as the pattern was completely installed in the memory bank and as easy as signing your name would be top speed.

Read my e-zine article for the Down Under and Up version to better understand why this needs to be programmed into your swing and old habits.
