I was on a Jetstream Super 31 this morning, not only was it NOT a jet (talk about a misleading name) but it seemed to take the pilots a worrying amount of time to get it started #2 engine started and seemed to rev up with a horrible whiny sound before stopping (smoke then seen coming from the front of the engine), they then started #1 up which seemed fine before having another go at #2

I'm not sure which was more worrying - the apparent difficulty in starting the second engine or the fact that the pilots who presumably are required to be highly-trained and semi-intelligent didn't seem to understand that a switch doesn't care how hard you push it.

Well they are jet engines...turboprops.

Meh.. they are getting the majority of their thrust from the prop rather than the "jet" so I still don't think they really count as "jet engines" except in the mind of you "engineering" types.

You do realise that ~80% of the thrust in a 'jet' engine comes from the fan at the front via the bypass rather than the combustion products, making it identical to a turboprop just with a cowling?

I honestly had no idea that bypass ratios were getting that high these days, the RR engine on the 787 has an 11:1 ratio apparantly

More efficient, innit.

Low bypass engines (turbojets) have piss poor low speed acceleration.

High bypass engines (turbofans) are better.

Capiche?

Well every day is a school day I guess

At the risk of embarrassing myself here can I take a stab that it would improve fuel economy at subsonic speeds? Whereas at supersonic you'd want either low-bypass or a turbojet?

You two need to sort out your bloody priorities. AaaaarrrghMP comes in here talking about her new Iphone and all you two do is talk bloody engineering. No requests for pictures, no subtle hint at the Myspace shot or the down cleavage titillating tattoo'd teaser, just bloody fans and props. Good grief chaps, standards have slipped way too far. CB, take them somewhere sordid and dripping and make men of them again.

Surely when you're talking about supersonic speeds it's all about the drag? (not THAT sort of drag zepperkins) and surely a turbojet or a low-bypass will give you a much smaller frontal area?
