Skymonkey13 0 #1 August 27, 2002 Can someone tell me the difference between jet prop and turbine prop engines? Thanx Quote Share this post Link to post Share on other sites
diverdriver 5 #2 August 27, 2002 Jet prop = turboprop = turbine prop. You may hear someone describe a 182 as a turbo 182. That means its' piston engine is turbo charged. But it is not a jet engine. A turboprop is a turbine engine (rotary) hooked through a reduction gearbox to a propellor. "Jet prop" is a misnomer since it does not get its' thrust from jet exhaust but rather the rotation of the propellor. Hope that helps.Chris Schindler www.diverdriver.com ATP/D-19012 FB #4125 Quote Share this post Link to post Share on other sites
jraf 0 #3 August 27, 2002 Turbine=Jet. It is a propeller powered by a jet engine. Apparently more reliable as a jet turbine has much less moving parts than a Piston engine i.e. less reasons for things to go wrong. Also, a Turboprop (as they often are called) has more power, hence brings you to altitude faster (long live the Otter)jraf Me Jungleman! Me have large Babalui.

billvon 2,991 #6 August 27, 2002 What's the difference between turbine engine aircraft and fighter pilots? After you taxi to a tiedown, the aircraft stops whining. Quote Share this post Link to post Share on other sites

[total sarcasm] Some people's children....I tell yah....."Yes, your Honor. There is a LITTLE exhaust thrust on SOME turboprop aircraft." It's called ESHP "Equivelant Shaft Horse Power". And yes, Mr. Poopy Pants, rain on my parade (post) the Twin Otter has about 70-80 pounds of exhaust thrust. [/sarcasm] Dork. Chris Quote Share this post Link to post Share on other sites
