Pratt and Whitney PW1000G PurePower Engine How It Works

[aegystierone]

Good to know innovation is still kicking in a decades-old technology!

[MarzEzOnline]

Ok, fine, you have me convinced.
Where can I buy one, how much is it, and how do I attach it to my bicycle?

The next step would be pitch control for the turbofan. So many turbofans sound like a buzzsaw/garbage disposal. We have seen the results of all that noise and vibration with an emergency landing of an A380 in Canada( uncontained failure turbofan) and two southwest planes(turbofan failures), sadly one fatality, a well loved lady lost her life. The geared turbofan will greatly reduce the fatigue on the turbofans of today and tomorrow. Nice going guys!!!

These engines have been introduced in haste. Around 31 "A320 Neo" aircraft of Indian carrier "Indigo" have been grounded as the new engine packed off mid air. Passengers reported hearing huge bang and the engine just shut down.

Do a gearbox design they said, it won't have too many teething troubles they said...

[MagniGamer]

You can definitely understand the presenter speaking, but the music is way louder than it should be...

Very nice, the conventional engine in the comparison with more stages must be CFM LEAP-X, it indeed has a huge 7-stage turbine for example.

[Stannas]

When will they decide to put constant speed propler technology into a fan?

[oisiaa]

The US Air Force needs to put these on the KC-135 Stratotanker. It would be a huge fuel saving program. It would be about 1600 engines too. Maybe reengine the B-52 with four of them too.

Imagine if it would also have carbon fiber blades, it would dominate the market hands down.

Slow blades and the highest bypass ratio combined would totally change the game, now it's a compromise between CFM/GE and P&W.

This technology may pave the way for a really short stubby jet engine with a whopping 20 feet in diameter. Engineering wise it's a long shot.

Does the fan rotate in the opposite direction as LPCs?

[LordBagdanoff]

Why is the air slower when the fan is bigger?

[KiwiAviatorHD]

On the last video, you can see some smoke from the pw1000g as well as the older jt9d engines.

[MinecraftCosmic]

but i don't get how this is more efficient, because now the fan spins slower than normal which means it will get less thrust, while the compressor spins at the same speed the fan is spinning slower than normal and in order to achieve the same amount of thrust as engine without gearbox the compressor now have to work harder which means it will eat up more fuel! so how is this gearbox more efficient? can anyone explain to me how is this more efficient?

[Capidiego]

This gearbox is like the used in turboprops???

[jessstuart]

What's the gear ratio of the transmission?

[Nikowalker]

@paduajoseph Thanks man, as a mechanical engineering student, I ve been always fascianatied by this sort of stuff.

[gearhead]

why oh why do the producers of most technical videos believe that viewers are blithering idiots who will become distracted or lose attention with out loud, nervous background sound tracks??? I am a highly developed humanoid who has taught myself to chew gum and walk at the same time. It is difficult but I am able to do it. Sometimes I do however, forget the left - right thing. Maybe I need a sound track to keep me focused?

[ThatSolidworksGuyVC]

Unducted fan variation of this engine when?
