This Genius Invention Could Transform Jet Engines

Оценок: 10300 | Просмотров: 1095438
Mike McCune is an engineer with Pratt & Whitney, the airplane manufacturer. After 30 years of development, he's created a gearbox for a jet engine that makes them 75% quieter and 15% more fuel efficient. That's a savings of about $1.5 million per airplane each year.

He must negotiated well with Pratt & Whitney to keep the design patents in his name. Usually most guys get their ideas taken with no credit.

Use of the word 'could'....fact that it's being reported on Bloomberg and not already in production...make me think...meh!

If the gears fail, the engine fail too. This is not a new ideal. The trouble is how to make it reliable and safe.

They spent 10B$ on a gearbox? Pretty sure there is more to this story than what Bloomberg is giving us.

There is nothing genius about this. Geared turbofans have been a well-known concept for a long time. Switching to something like a biogas would be the next big thing. There is only so much you can do to make a turbo-fan that much more efficient. Switch every flying thing to biogas and we will be able to see a drastic change in the climate.

Looks dangerous in adding a component far more complex than the original system, hence increasing the chances of catastrophic failure. I suspect this is why it's not used on passenger aircraft flying 4 billion people a year.

Geared engines have been around forever. You can tell this is a CVT by the requirments of the design criteria. Why not electro couplue the fans to the engines so the wire runs will be very small and contained within the power unit?

They need to implement the srf71 engine design. Turbo/ram jet engine. You'll get over 50% efficiency with a ton of power. That was design over 50 years ago.

Not a huge technological breakthrough but another complication added on engines which are already complicated.....wonder after how long in service will arise the problems of gearbox failures....

In 1969 an electrical enginner student in college told me "the tech to manufacture a bulb light that uses only 12 watts to shine like a 60 watts one exists, is not in production because there are companies that would loose BILLIONS of dollars if implemented." You will remember my words some years from today". Many tech secrets hidden from us. Ask the pharma industry.

Could save lots by running bifuel,compressed air with jet fuel. Better yet liquid o2 and h2 would be ideal.

Such a no brainer idea. But throw enough money and work in it you can get it done.
Mark S (3 месяца назад)
Sceptics, here is the tech info: The Pratt engine is radical because it has a 12 to one bypass ratio. Other jet engines have about a 5 to one bypass ratio, meaning much less efficiency and more fuel burn. Bombardier's development of its new mid size CS100 and stretch CS300 jets was with this engine with 3 different thrust rated units. The actual fuel burn reduction was 21 percent on the partly carbon fiber jet, once they were put in service. AirBaltic has flown over 1 million passengers on it's stretch CS300 in Europe. Delta Airlines 3 years ago placed 75 Firm orders with another 50 Options for both Bombardier versions. Air Canada placed 75 Firm orders 1 1/2 years ago. JetBlue just placed 60 Firm orders and options for another 30. The CS100 will seat from 108 to 132 (29 inch pitch) and the stretch version CS300 will seat from 130 to 145. AirBaltic seats 135 on their CS300's. Airbus will make almost all of the Delta versions in their Alabama plant and it has been renamed the A220-100 and A220-300. Airbus has dropped the A319, so the A220-100 will replace it. Airbus uses this as an optional engine on their A320NEO. Many U.S. based airlines will prefer to convert their future A320NEO orders to the A220-300 as it's the only 100 percent all new mid size jet on the market. Boeing will catch up with a replacement for the 737 in 2022 or 2023.

A machine itself could operate without the need of a fuel source still Jet engine still requires fuel to operate so no engine could transform but only evolve until maximum entropy.

0:44 $10 billion and 30 years for a geared turbine engine?? If his estimates are correct a savings of $1.5 million per aircraft per year...lets say for 100 aircraft..will take 66 years just to get your money back from research before you even “make money” off the idea. Probably not the best investment so far

The difference in optimum speeds for the compressor and exhaust turbine has been known since the 1940s; the only breakthrough here is designing an efiicient gearbox that can handle the stress of high speed operation without catastrophic failure. Testing is needed to be sure these things don't have a tendency to explode like a bomb in flight!
Tynan Cravy (3 месяца назад)
Modern jet engines are just fine for the environment. They have a thermal efficiency usually about 99%. Stupid Bloomberg. The turbine drives the compressor. If the tips were to go super sonic, the blades would destroy themselves. Pollutants usually not a problem on a jet engine.

I wonder what the other repercussion is. For example, how much energy does the planetary gearbox take in terms of friction and oil usage, and then oil cooling, and then the cooling of the gearbox mesh gears. I'm sure they've obviously gone into this, but there would have to be some energy drawback with any kind of gearbox, as gearboxes fundamentally eat energy for breakfast. I just wonder what the efficiency ratio is in terms of the reduction of supersonic tip energy x the gearbox friction energy. Anyone from Pratt and Whitney no any of these figures, just out of curiosity?

jet engines are wasteful engines unfortunately that's the only engine that can propel planes. Imagine burning a gallon of fuel every second the world will eventually run out of oil.
