What's wrong with this plane?

[T-Bird76]

Ok I hope I'm not the only one to pick up what's wrong with this plane.. Anyone else see it?

Its a turboprop and its name is twinjet?

[nwafan20]

That would be my guess.

[T-Bird76]

Yep exactly, what the hell airline names themselves Twin jet and uses props?

[nwafan20]

"Twin Jet, the airline of really really stupid people who don't know the difference between a prop and a jet! Fly us today!"

well tommy, that engine is basically a jet engine, just has a prop attached to the shaft. it works in the same way, but instead of providing thrust, it provides torque to the prop shaft.

Matt its a dam prop! There are big external blades that spin around, its a prop and a stupid name for an airline.

You are both right! I am so confused!!!! :lol: :wink:

I'm glad I can be of service Fred, LOL :lol: :lol:

Hmm, if that's a Beech 1900, it uses P&WC engines. My father worked on the design of these, and they're turboprops.

[Derf]

We got that :D

tommy, i agree but the engine is still a turbine (jet).

[Nonstop2AUH]

Well, this is what in the early days of turbine-powered propeller aircraft (say the 1950's) was often marketed as a "propjet." This was in order to distinguish such aircraft from the then-common piston aircraft, which were slower and rather less comfortable due to noise and vibration.

As for the plane in the picture, in engineering terms, it's a turbine aircraft. But as everyone can see, it has propellers. So, in the 21st century, I would say it's a bit much to call it Twin Jet but then again, maybe that is the name of the company and they also operate pure jets. Or maybe they are just being cute and reaching back 50 years!

[nwafan20]

Nope they only operate 9 Beech 1900's (once C variation, the rest D)

[GrummanFan]

Well according to the link that Fred posted, the jet contributes little to the overall thrust. Its only point is to turn the prop, which then produces the thrust. So calling themselves Twin Jet is silly, because that implies they are flying under jet power, when technically it is propeller power (at least by my logic).
