This Genius Invention Could Transform Jet Engines

6270 ratings | 693688 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.

problem: out put shaft needs to spin slower than input shaft. 10 billion dollars and thirty years later... "lets use a gear box"

But less fan angular speed would produce less thrust! Unless it can be increasing tuning the blades pitch

To bad they don't tell the story of air for fuel...just like the RC 30 foot 747s compressed air turbine engines...these toys use air to bad the real toys don't...

Paul Shepherd YouTube is a great research tool. If you don’t believe it then show me the data that isn’t on YouTube regarding jet engines not running on air.
Paul Shepherd (28 days ago)
Chris Madsen Only people with zero knowledge of physics or how jet engines work believe that, and it is NOT true. Do some research that doesn't involve watching YouTube videos and you'll understand.

I have heard that this engine could be possibly used to power the new NMA aircraft from boeing if they decide to go ahead with it, but that would be a while away. Still its interesting because today geared engines are used small short range planes, if boeing does decide launch the NMA plane with this kind of engine, it would possibly become the first mid range to long range airliner to use a geared engine unless someone else builds it first!.

This is a concepts similar to why one wasn't able to add jet engines to a helicopter, the blade would have to stop or fold , at high velocity, the blade become a burden to the jet flares pressure and super sonic barriers, we now have inventions of bladeless fans replacement tube strip beams and electric/electron combustion thrust that would replace the fossil fuel limited volume with electric solar or mini nuclear amped batteries that would ride sound issues at land path areas, along with the flight cost almost entirely, which is what one would recommend the company to look into.

Nothing new in this. The RJ 70 had such a gearbox. The BAe 146 is powered by four Avco Lycoming ALF 502 turbofan engines, which are fixed on pylons underneath the aircraft's high wing.[6] The ALF 502 was derived from the Lycoming T55 turboshaft powerplant that powers the Chinook heavy transport helicopter. Notably, the ALF 502 had a very low level of operational noise, much lower than most other competing aircraft. This was achieved largely through the use of a geared turbofan engine; the gearbox allows the fan blade tip speed to stay below the speed of sound dramatically reducing the aircraft noise. Additionally other sound deadening measures include a high bypass ratio compared to contemporary aircraft and additional sound damping layers built into the engine.

Pratt & Whitney could have saved themselves 9.5 billion dollars had they just hired a competent inventor instead of think inside the box engineers. Not only would they have a quiet turbofan engine, they would have saved considerably more than 15% fuel and have major cost reduction for manufacture.

How is this a genius? A genius is something that no one will ever think of other than the genius himself. For sure, countless of people have thought of using gearbox to sync 2 objects spinning at different speed, i mean, look at your cars. For sure, the mechanical and technical aspect of this is extremely complicated, but not genius.
Stephen Barnes (6 months ago)
cool. Now take that larger rotor and use the full circumference into an electric motor and compress it down to where a small amount of fuel and air is burned under high pressure. Just for fun of coarse to see what consumption of power is. Might be cheaper to run 1 turbo generator and two electric fans

I don't get it'! If they needed to slow down the fan, just use a smaller pinion, larger 'bull gear' like they've always done. Give the problem to a high school kid. He'll have the answer by quitting time.

The Chinook helicopter uses the T-55-L712 turbine engine. It uses a reduction gear also. Funny how it took so long for commercial aviation to figure out that reduction gear boxes actually provides more powerful, more efficient engine technology to aviation. The American military already knew that. Lol.

in the 80"s, Mcdonald douglas made an jet engine fan propeled by an turbine (an propfan), in 1949 an austrian engineer Bradner made the nk-12 for the soviet bombers that is one of the most powerfull and eficient engine even by today standart. An flying wing jumbo jet would be an inovation, making an engine with a bigger diameter so you can fit the transmission inside shaft is why everybody thinks this is propaganda

Jay Edlington (7 months ago)
People, people... The metals can absolutely withstand spinning at 100K rpm. It's just the balancing and oiling, and other fine details that make it a 100h engine or a 10,000h engine. But most certainly we can prepare sufficient alloys, as well as sufficiently machine them to fit within 2/1000" tolerances (1/500 of an inch). It seems perfectly reasonable that a multimillion dollar engine would be able to do this gearbox trick.
Mihindu Pulukkody (7 months ago)
Can jet engines work on hydrogen gas? If can, then can manufactures like Pratt & Whitney, use electrolysis to separate hydrogen and oxygen from water and use that hydrogen to power the jet engine. If future jet commercial airliners have water in their tanks, would they be less destructive in a crash?

This is old technology that has already been obsoleted by antigravity. Trump needs to force the issue and release antigravity tech to be used in airliners, trains, and even cars. It is way overdue.
Thomas Sadlowski (7 months ago)
Lol if P&W would have only thought about their engine also need to be good in ground operation. Unfortunately they´ll fail there - core-engine-temperatures are too high on the ground so it needs way longer for them to cool down in ground idle before take off - leading to missed take-off-windows and a lot of fuel burned on the ground. Infact they burn so much fuel on the ground, that even their excellenent sfc in cruise isn´t able to give them an positive overall result. V2500-numbers increased again because the customers refused to equipt their new million dollar aircrafts with the p&w-engine unless the redesigned parts the engine causing the problem. So in theory they brought up (again - yes,the geared turbofan is not a P&W-invention) a good concept, but they showed a poor performance baking that theory into a groundbreaking engine

Damien Thorn (7 months ago)
As a highly experienced fan jet engineer it is my expert opinion that this will never work because the rotational velocity of the fan at subsonic speeds will be indirectly proportional to the amount of air it will pass during each second of operation. Less air enters the combustion chamber at higher fan speeds resulting in lower turbine speed after combustion which in turn slows down the fan even more. Well actually I haven't got a clue what I'm talking about I'm just seeing if any dumb fucks will actually believe this pointless comment!!
niklas alagadi (7 months ago)
rolls royce's trent7000 engine has 3(!!) shafts optimizing the speed of the fan, of the compressor and of the turbine so the revolution has already taken place
Ken Bellchambers (7 months ago)
There is no way jet aircraft can be environmentally safe for several reasons: One- high altitude heat deposition is the principal driver of severe weather. Two- jet engines exhaust gasses are toxic carcinogens. Three- jets rake out ozone from the upper atmosphere and drag the ozone to lower levels. Ozone depletion at high altitudes reduces the blockage of U.V. radiation, and ozone deposited at lower levels is corrosive and causes plant disease. Four- jets contaminate massive quantities of water vapour, turning the water vapour into acid fallout. Five- The water vapour dragged from the upper atmosphere is often dispersed at lower levels without rain, leading to more drought. The jet industry and the tourism industry are two of the largest employers on Earth. Will we kill the planet for money or will we wake up to the disastrous consequences of arrogant and unsustainable jet travel?
