what are the technical hurdle's involved in turbine automobiles ,

i know tanks can be turbine powered and i'm sure torque is abundant but milage

is poor .


Also , Rotary Radial anyone , never even heard of this until yesterday .

not a rotary or a radial , but a engine where the whole engine spins ???

some body explain that to me .

Turbines: Low torque, spin to the moon. Kinda like a Wankel on steroids that way. They spin tens of thousands of RPM or better.

They do not like to change speeds, so a direct connection to the drive wheels will not accelerate that well, at least at first, but the top end will be phenomenal. They burn massive amounts of fuel.

The rotary was an interesting engine. The prop was bolted to the crankcase, while the crankshaft was bolted to the airframe. The whole thing spun together. It allowed the engine to be much lighter, because the whole thing served as a flywheel. (Early engines often needed weighty flywheels because they ran unevenly and pretty rough.) They had a very odd intake system; I think the fuel was fed into the crankcase through the crankshaft. It went into and then out of the cylinders (through the piston??), then back in again where it was burned. The exhaust valve was on the "head". It was pretty inefficient, but relatively lightweight because as mentioned it didn't need a flywheel.

It used a total-loss oiling system, where oil went in and got whirled around with the gas and air in the case, and eventually was expelled out the exhaust. It was castor bean oil, and it gave the pilots the screaming s**ts because they wound up ingesting it.

One of the most famous early rotaries was the Gnome Monosoupape. Soupape is the French word for valve, so it was the "one valve" because the exhaust valve was the only visible one. http://en.wikipedia.org/wiki/Gnome_Monosoupape

I love some of this early aviation stuff. (IMG:style_emoticons/default/smile.gif)
