AFAIK, a "gas turbine engine" can equally apply to a turboprop OR a jet.

Mohican, I'm confused are you implying that the Bear does infact have Jet engines? If so it can only be via semantics surely? The Bear has always been widely considered to be a jet engine free aircraft

Unfortunately for the designers, piston engines simply wouldn’t provide the lift and speed necessary to haul such a heavy payload at high enough speeds. Jet engines would be able to provide the needed power, but would be too heavy and burn too much fuel to give the plane the necessary range.[1]

Designers opted instead for a turboprop aircraft. This would provide the range and speed close to that of a jet, but would still enable the aircraft to fly huge distances.

The Tu-95 is the world's only swept-wing turboprop ever to enter service. Its distinct engines, each with two counter-rotating propellers, also make the Bear the fastest propeller-driven airplane ever built.

The original Tu-95 was designed to carry two nuclear bombs to targets in the continental US.

http://en.wikipedia.org/wiki/Turboprop
Gas turbine engine = jet engine. Turbojet is what's fitted to jet fighters. turboprop where a power turbine at the rear of the engine powers a shaft which turns a propeller. Helicopters use turbo shaft engines, where the power turbine turns a shaft and through a g/box to the rotors, http://en.wikipedia.org/wiki/Turboshaft. Turbofan engines are the massive ones on big jetliners. The turbine pushes some air around the engine and this is used as direct thrust .http://en.wikipedia.org/wiki/Turbofan

I might need to get in touch with a fair few websites and aircraft manuals to put them right. So we should say the Bear does not have turbojet engines? Is that 100% correct?

Sounds a bit like semantics to me, but i'm know mechanic.

Few refs where they say jet engines..

Would it be more correct to say it doesn't have turbojet engines then?

Correct. A turboprop is a variation of a jet engine. A jet engine uses the thrust coming out of rear to push the aircraft forward. A turboprop has power turbines which are driven by the thrust and they turn a shaft which through reduction g'boxes turns the propeller..

As a man who likes his warm beverages, Tikay, do you give the barristas your real name when they ask for it?

I've decided I don't want to walk around town holding a cup with my name on it, so this morning in Starbucks I went with "Tim".

It wasnt for any particular reason. It is sufficiently uncontroversial as not to warrant question and yet sufficiently different as to be distinguishable from the other drink-getters in the queue.

I'm not sure whether on my next visit, I will stick with Tim and create an alter ego or whether I will choose a different name. If the latter, the gambler in me wants to find out what the most ridiculous name I can get away with is.

"Betty"
"Baron von Schlafzimmer"
"The Marquis of Tickle"
"Costa"
"Marion Kunterblast"
"Tikay"

Who knows how this plays out...

While sitting in a similar establishment, snaffling the free WiFi (someone uses blonde too much...), I've been joined by a man who seems to think it is OK to cough without putting his hand in front of his mouth.

All over the table. That's where my tea is!

And he's reading the Daily Mail.

If he pulls out an @rsenal shirt, I might make the evening news.
