Mmmm, yeah, jet, absolutely. Those funny blade thingies on those rotating hubs by the 'jet' engines must be to blow air around when they fly somewhere hot.
Actually Those "funny blade thingies on those rotating hubs" are powered by a jet engine. They just attach those whirly bits of wood to the compressor shaft.
The turbo prop is just a turbojet with the whirly bit stuck to the front. It gives the aircraft a short take off and landing (STOL) capability necessary for commuter aircraft. Britain had the first turbojet with the Meteor in 1945. I think it was fitted with the 'Trent 50' engine.
Filthy Engineer, yeah I know, but as I understand it very little thrust comes directly from the engine itself. that makes it a turboprop, not a turbojet. I suspect the journalist has just gone 'ok, 1 wing each side and is not a bird = jet'. Yes, I know that strictly speaking many actual 'jets' are turbofans, but presumably journos think that turbofans are supporters who get to the ground really fast.
Actually I should have mentioned that what got me in the first place was describing the aircraft both as a jet (headline) and a turboprop (text). On that basis I am declaring that penguins are fishbirds :-)
Add insightful or amusing remarks for me to think on and respond to. Or add annoying comment spam for me to waste time deleting, in which case may your genitals turn square and fester at the corners.

ReplyDeleteSorry to be pedantic.

The 'funny blade thingies on those rotating hubs' are indeed spinning round to keep the pilots cool.
ReplyDeleteYou should see them sweat when they stop.

ReplyDeleteChuckles, that's gold.

ReplyDeleteYou'll never go wrong assuming idiocy on the part of journalists...

Heh!
'but as I understand it very little thrust comes directly from the engine itself.'
ReplyDeleteNope, On a Cessna Caravan for instance, the turbine 'exhaust' thrust contributes about 8-10% of total, if memory serves correctly
It's powered by a jet engine so it's a jet.
ReplyDeleteResearch 'turboprop' and you will see a jet engine.
And I would be VERY surprised if those "whirly bits" were made of wood.....
