Aerospace questions you got it post it

If you have any questions about aerospace post them in this thread. I guarantee all will be ignored in turn

What is the bypass ratio of the GE F110 turbo fan used in the F-16 C/D; and what is the pressure ratio of the third stage of the compressor?

[<>Major_Havoc<>]

I believe it is h~372x - 24y^4 But im a bit rusty so um my rough calculations say 3
Mx + (27)

[firstknife]

which block of f16 c several of them have converted over to P&W

[kemosabe]

ok here's the scoop the whole inlet scoop. The bypass ratio for the P&W F100 and the GE F110 are both about 1.5:1 bypass ratio. It is a low bypass engine. There is no third stage compressor, only a low and high. The Pratt and Worthless has a total of 13 stages of compression. 3 in the fan module and ten in the core module. the total compression ratio is about 30:1

the formula for figuring the thrust for a turbine engine is F=MA (F= force, M= mass, A=acceleration)
to calculate force is F=(Ms(V2-V1))/g
Ms=mass airflow through the engine (pronounced "M" sub "s"
V2=air velocity at exhaust
V1=forward velocity of engine
g=acceleration of gravity, 32.2ft/sec squared (or 9.8 meters per second squared
F=force which is also the engines thrust in pounds
remember is one variable is in metric all of them must be

and after the block 25 production run (all previous blocks were pratt and whitney) block 30's, 40's, 50's, and 60's are GE. block 32's, 42's, 52's, and 62's are pratt and wothless

enjoy

Who is kemosabe my first guess would be price but anyway if it is price how whould he know this stuff i think hes just making it up. lol im gonna feel like a fool if this isnt price if it isnt i apologize ahead of time lol. if it is price i just want to say to you{ Sammons can read no further.xxx} (steal sammons old pack and give it to me) lol anyway yeah your wondering right now how can he speak so long yet actually have nothing to say well its a gift and a curse i suppose. But i am going to go study my CERT material (actually im going to go play video games) peace BATMAN

[kemosabe]

you know that was a pretty good guess for someone who is that dense. But your questioning my abilities has inspired me to come up with a very good aerospace class. your friends will love you for it I guarantee

[Major Destruction]

I expected that he would either know the answer or know someone who could tell him. I already knew the answer, this was just a test for the new AEO.

[kemosabe]

you doubt me, that's not funny just because i don't have a degree doesn't mean i am stupid. just an under achiever. it is a prime requisite for being a crew chief.

Quiz-type question for other cadets:

What do CTOL, VTOL, and STOVL mean in relation to aircraft?

Don't answer in this topic. Look for instructions in the "Pop Quiz" topic (still under "Anything Aerospace").

Did you call me dense? how dare you call the all rocking and rolling batman dense> I laugh at you for making such a rediculous accusation. Nerd mechanic

[kemosabe]

yes i called you dense, and the time it took for you to answer back is a pretty good indication of just how dense you are. nerd mechanic?? you are calling me a nerd. son i have achieved levels of cool you can only dream about in your youth. and if you ever try to insult me again i will have sand installed in every orifice of your body. I brought back plenty of samples from the desert for just these sort of occasions

[<>Major_Havoc<>]

Please "these sort of occasions" I believe the correct grammer would be for these sorts of occasions, mr multi level coolness dude learn how to spell then try and make fun of me lol (peace) no more name calling that above is the last, I mean absolute last mean thing said, deal. Awesome your a pal.
