I am so embarresed to ask these questions

[JA Yawd Bwoy]

Are turboprops Turbine engines?

and do Turboprops have spoilers?


Sorry for the dumb questions but I don't know and I really want to know this info. WOW

[drew09]

no, they aren't the same
turboprops are a propeller driven engine with a turbine at the rear of the engine that the exhaust is compressed and then pushed through

turbo props

turbine engines are your jet engines you see on larger airliners, im sure someone can elaborate more about them..

Turboprop-Turbine engine with a prop.
My planes did not have spoilers (AT-602)

[JA Yawd Bwoy]

Thanks whewww. So a turboprop would not count as A turbine rating?

[BobDDuck]

A turbo prop is considered a turbine engine.

It's really the same, but it has a prop attached to the front of it.

DO WHAT?????????? I dont know if I read that right but let me clarify in one easy sentance.....


Turboprops are turbine powered aircraft...THey are propelled forward by a prop which pulls them through the air. This prop is independant of the engine. Jet engines which are also turbine powered use the thrust created to move by forcing air out the back of the engine.

thankss guys

I certainly don't want to discourage questions, but it sounds like this book would be interesting to you.

The Turbine Pilot's Flight Manual

Yes Turboprops are Turbine Engines just use a prop to produce thrust


Our planes do have spoilers (ATR-72) but we dont have a separate control for them they are proportionality controlled with aileron deflection.

You should be embarrassed that you can't spell "embarrassed."


Speaking of spoilers: a fun fact.


The B-52 and T-1 (BE400) do not have ailerons! All spoiler baby!

Same for the C208.

The early model (Pre G) B-52's did have small ailerons between the inboard and outboard flaps. My guess is they deleted them to save weight and reduce complexity.

You shouldnt be embarrassed to ask questions. People here are more than willing to answer questions.

That's a really great book. It's a must read IMO.

Don't worry about asking questions, who knows? you may ask something someone else wants to ask but doesn't have the guts to do so. Or, the resulting explaination may clear up someone else's confusion.

Better to perhaps be a fool for 5 minutes, than a fool for the rest of your life.

Actually....depends on if you are talking about a turbojet engine or turbofan. A turbojet engine uses the thrust out the back to produce forward movement, ie, a jet fighter. A turbofan, especially a high bypass engine, which most airliners and bizjets use today, uses the thrust from the fan on the front just like a prop, but ducted, to produce the forward movement.

Not a dumb question. My girlfriend thought planes had gas pedals....I mean how else do they move on the ground?...Right?

The PT-6 is pretty interesting to read about. No physical connection in the hot section. Seems a little weird, but is pretty interesting.

I think in most turbofans, somewhere around 70% of its total thrust comes from the bypass air.

The CF34-3B1 (on the CRJ200) has 85% bypass air.

Funny story about the gas pedals. I took a friend flying once who had never been a small plane. I had them "drive" out to the runway using the yoke. I even was weaving down the taxiway a bit with the peddles just to make them steer it back. Of course, I forgot about it and on the way back in I was steering with out touching the yoke (of course) and they got suspicious.

kinda sorta the same thing....a buddy of mine told his student they were required to taxi down the yellow "S" line that ran down the whole taxi way (gets confused for a runway)...tower wasn't amused when they started taxiing from one edge to the other back and forth.

Unless you're talking about "Turbocharged" or "turbonormalized" (which is a piston engine with a turbo system) if it says "turbo-whatever" it's probably a turbine engine.

Turboprops, turbojets, and turbofans are all turbine engines, but harness that turbine energy in slightly differing ways to produce thrust.

Just to be confusing, some helicopters with jet engines are said to have "turboshaft" engines, because the turbine simply turns a high speed shaft coupled to a drive gearbox/transmission.


Like a few folks said above, "The Turbine Pilot's Flight Manual" is a goldmine. It's worth EVERY cent.

Has a CD with animations and videos nowadays, too.

Here's a diagram of a type of turboprop you would find on a P-3/C130 type of engine
http://en.wikipedia.org/wiki/Image:T..._operation.png

Also, don't forget most helicopter motors are turbines, connected to a transmission.

And yes, the PT-6 is an interesting type as it has its turbine section (after the burn) separate from the compressor shaft. Free spinning turbine connected to a reduction gear box connected to the prop. Also the PT-6 is a reverse flow design, where the air enters the intake and goes thru the engine from the back, and flows forward thru the compressor, combustion chamber, power turbine, then the exhaust gets routed out the sides and rearward again.
