Traditionally, turbine engines have been great with overall power, but horrible with transient response. (And you thought "turbo lag" was bad, "turbine lag" is even worse!) They're also ear-bleeding loud, and produce incredible amounts of heat. Not to mention going through fuel like scotch at an AA meeting.
The up-sides don't seem to be enough to warrant the $$$ investment required to mitigate those down-sides. It'd be cool to be proven wrong on this, though! --DD |

That excess heat could be used as a cool snow melt feature

Another fringe benefit for our four season friends:
With proper ducting you could have a very effective defroster. |

In the Army I had the opportunity (misfortune?) to stand near the back of more than one M1. The heat coming out the exhaust is amazing. They also have to "rev up." The sound they make starting up was pretty bad-ass, though, especially when a whole company of tanks starts firing up. |

![]() Turbine 914? Not that turbine. It's going cheap because it's timed out and needs maintenance. Now a 160hp 200lb turboshaft engine may be suitable for a vehicle such as this skimmer. Looks like the perfect machine to get out to the icepack for the season of the killing. |

Chrysler tried it back in the early sixties. They leased them to a few families around the country to try it out. There was one close to my house. And, of course, Leno has one. (IMG:style_emoticons/default/biggrin.gif) When I was a kid, I actually got to ride in one of them! It was so cool. Only sound I heard was the tires. Mechanics Illustrated magazine had run a contest that was really a way to locate potential test owners. Our neighbor was given one for a year. The car did have issues. He gave us a ride just before he had to return it. |

![]() ![]() ![]() Buffalo Nah. Some snow don't blow,they're squeegees for miles of runway in the rainy seasons. An Air France hydroplaned off the end of the 24L-06R runway into a ravine here in TO. No casualties,Airbus burned during heavy thunderstorm. Puddles. http://en.wikipedia.org/wiki/Air_France_Flight_358 ![]() |

Turbines are generally designed to operate at 100% Ng and have their loads altered by means of the drive system.
Because of that, the fuel control isn't sensitive to throttle changes. The ultimate way to outfit one of these turbines would be through the use of a hydraulic drive system that can vary volume to alter the vehicle speed, so the engine can run at 100% Ng and stay happy. I've been wanting to install a T58-GE-16 engine into a VW bus for a while now, and I know my way around them really well. |

I am surprised no one mentioned Jay Leno and his turbine bike. Never embedded video sorry.

Turbine! not turban.
In those days the b+w tv showed the amazing STP car dominate the field. A legacy of wrenching history of the family likely means you had an early start. ![]() Thinking,designing,building a car/bike/boat/plane or rocket is the American way. |
