ADRidge Posted February 25, 2010 Report Share Posted February 25, 2010 Why is it exactly, that tip jets, or tip engine, helicopters never came into style? My understanding, from walking around the Smithsonian NASM annex was that they just burned a ridiculous amount of fuel. If I'm reading the technical data on this correctly, 22 gallons of fuel will get you 60 miles. 22 gallons of fuel in a R-22 will get you almost three times that distance.

R22139RJ Posted February 26, 2010 Report Share Posted February 26, 2010 If you havent read "The God Machine" I highly reccomend it. Its a great history of helicopters and describes the Tip-Jet helicopters. If my memory serves me correctly, they had the pilot use his legs as landing gear and could hover a little bit. The fuel burn was through the roof and tip jets are basically rockets so the noise was outstanding. The book is a great read. Quote Link to comment Share on other sites More sharing options...
Gomer Pylot Posted February 26, 2010 Report Share Posted February 26, 2010 Much of the noise a helicopter makes comes from the engine. When there are multiple engines operating near supersonic, it gets very, very loud. Plus, it's just not very practical to operate engines spinning that fast. Far better and more economical to use fewer stationary engines. Cost is always an object. Quote Link to comment Share on other sites More sharing options...
natty dread Posted February 26, 2010 Report Share Posted February 26, 2010 From my reading about another rotor-tip engined craft, I think there may be some problems with autorotation with these types as well as the horrendous fuel consumption.
