This Genius Invention Could Transform Jet Engines

9589 ratings | 1009025 views
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.

"Transform" erm no, saving 15% on fuel is no mean feat but saving 1.5 million per aircraft per year is nothing, British Airways spends that amount on oranges.

Ok this was in 2016 did these engines get approved and are they being built for commercial use ?

How is this any different from a turbofan?

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.

Innovation is a need rather than a requirement. Thats how the car was made. Thats how planes were made thats how simple things like chair and the simple wheel came into existance

Was expecting a new type of engine that's why watched the whole clip, found out it was a fucking gearbox that already has been done and figured out 30 years before this dodo.

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.

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.

You should have gearbox like a car so pilot can change gear if he wants.
Kojack (10 days ago)
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 (10 days ago)
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?
Jod Tan (27 days ago)
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.
Matt Mann (29 days ago)
Old news. Just one more incremental step to make the jet engine better. It's the small steps that's making the jet engine one of those modern marvels of the aviation industry.

Two different pieces of a drive system requiring different rotational speeds, lets put a gearbox between them! REVOLUTIONARY IDEA, nobody ever thought of that before! Am I missing something here or is that too basic for words?

The greatest innovation would be if Pratt and Whitney combines Stanley Mayer's water hydrogen technology using electrolysis for this new engine. There would be less casualties to passangers when the tanks of the jetliner are filled with water in case the plane crashes.

What a colossal waste of $30 billion and 30 years for a "lab" quoted 15% fuel consumption reduction. Surely P&W could find better use investing that money, energy and time in RnD for future non fossil fuel propulsion alternatives? Just think, they could have made a major breakthrough in alternative methods of propulsion by now, had they started 30 years ago. We could all be flying around in planes propelled by Giant genetically engineered Moths by now!

An Electric Drivetrain would solve this problem. Drive the ducted fans with motors powered by a large turbine or two, which could be mounted anywhere (maybe in the tail)

A jet engine running even closer to a phone ringing Momma, would not curtail a phone call, she would just up the ante and shatter the fan blades. Moral of the story, never ring Momma whilst testing precision apparatus.

Pratt and whimpy wants everyone to believe they were first to the geared turbofan. They were not, geared turbofans have been around for a while. Even then they spent so much money on the gearbox while everything else on the engine breaks. Not so dependable engines I would say. Evendale Ohio has their number.

bullshit. all blade propeller engine must rotate under super sonic speed at the tip of the blade if not nearly 0 thrust is the result this gear may reduce 1 million/years fuel cost but would raise the engine price and maintenance cost and who is best to maintaining those engines other than those that created that engines?

joseph prosser (9 days ago)
Lycoming/Honeywell produced geared turbo fans for the BAE 146. The ubiquitous turbo props include gears to reduce the speed of the turbine power unit to drive the propellor. P&W have taken on this idea and applied it to jet engines of higher power output. Rolls Royce are taking the idea yet further and are developing its use on the very largest of jet engines such as the Ultra Fan.
