OT: F-35 Lighting II engine roars to life

[TucksonSonny]

P&W F135, 40,000 lbs of thrust in AB during the test, most ever from a jet fighter engine. Also P&W has just upped the rating of the engine to 43,000 lbs capable.

Last time I checked it was the Saturn/Lyulka AL-41F turbofans rated at 44,100 lb of thrust in afterburner.

(BTW, test with the Saturn/Lyulka AL-41F was done years ago on a Mig-25)

...and the prototype F135 produced 52000lbs of thrust back in the JSF competition. Now that it's settled that "ours" is bigger, let's just drop this nonsense and get back on topic.

Thrust doesn't say a bit, as explained by a Lyulka/Saturn PR dude on a video, it can reach 25k kgf, but if it has a resource of 100 hours, well, it's not a good engine. The Russians know, they always lagged with the engines for their fighter programmes, so even if Russia will have a MFI prototype in 2008, its engines will be ready by 2012 at the ver least.

 

and the al-41 isn't nearly as big as a f-135, so that's not really a fair size comparison, like comparing the engine of a CRJ-700 with that of a B777/A380, they're both turbofans with high bypass, but then it all ends.

Thanks Force...I was just about to say something about the abyssmal TBO of the AL-41. :D

Last time I checked you were Canadian so I guess “ours” is not going to work for you either. ;)

[Guest IguanaKing]

LOL. The F-135 engine is manufactured by P&W C. Any guess as to what the C stands for? :smilewink: Magellan Aerospace is also a Canadian company. Its a joint venture.

I can imagine that it is cheaper to make the F-135 in Canada. :D

BTW, my sister her husband has family in Canada.

[Guest IguanaKing]

Actually, its more expensive...but they've got the know-how and nobody is going to skimp on engine quality. If we did, we'd turn out an engine with a TBO of 100 hours. :D

Haha, now that was a low blow.

 

Tuckson, since we're already off-topic, any news on those new Russian engines?

No, but think about how much raptors you could kill with a Mig 1.42 in 100 hours. :D

Oh, the 'new' (ie smaller, able to fit in su-35/37, based on the big 1988 al-41) Al-41 has a reduced thrust of something between 15 and 18 tonnes, but also has a longer TBO than the al-31FP (the mki one, with additional thrust; 13300 kg and TVC). So the al-41 was derated, and now they (Saturn/lyulka) call it "a true 5th gen engine". :P

I remember him saying something like: "Other engine manufacturers say, when they get 25000 kg of thrust that it's 5th gen, but you can have a 40W lightbulb, and run it on 100W, it will burn out very fast, but produce more light. Our engines (some new al-41 mod) have both he thrust and long TBO.

So they first derated and changed the al-41, now they're starting to slowly uprate them, although I doubt they will reach the 25 tonne mark, 21-22 perhaps.

Anyway, the F135 is a key enabling factor for the F-35. It is very difficult to match advances in engine technology, because it involves very advanced materials science, mechanical engineering, production methods AND electronics.

 

Just like with the J79 and F100-PW-220, for an aircraft that has to be built in large quantities the engine is the alfa and omega of the story. Without the engine power and reliability the single-engine, lightweight F-16 could never have become the success it has been.

 

One of the big problems facing Rafale at the moment is the problem to have enough trust out of the M88-3C engine at an acceptable price level.

 

Eurofighter escaped this dilemma by designing an essentially smaller and lighter aircraft.

 

At the moment, only the Russians are in theory capable of fielding an equally powerful engine, but are not about to do so soon.

None. You'd run out of engine time from deployments and exercises.

 

Oh, you didn't do any? ... um ... not so good ;)

Wow, someone get out the burn unit stat :rotflmao:
