That's an awful lot of weight and complexity to oil some bearings. I'd seriously consider a lossy type system and do it with waste motor oil or something. Just use the vacuum from the intake and burn it, most of the model airplane turbines are setup that way. Unless you're planning to drive other accessories or a lift fan with the gas motor.

I'm pretty sure the propulsion fan will be driven with the gas motor as well, and the turbo will be used to inflate the cushion - sounds strange, but the way it was performing, it was putting out a lot of volume with not much force, which would work fine for the lift but not so much for propulsion.
Mostly I think it was an excuse to build a jet engine.

That's sue to the expansion cause by the thermal change, after the ductwork to get it to the skirting I'd bet the volume is greatly decreased, as it will have cooled down quite a bit.
The key to getting thrust is building a nozzle for the output to channel the gases.

yeah... a nozzle... hmm that might help :roflmao:
the "nozzle" on the prototype was a random chunk of exhaust tubing we found on the floor, I think it came off the donor vehicle the turbo came from. We sawzalled the end mostly flat and booger/tack welded it back onto the flange that clamped to the turbo.

a pulsejet is on the list too, and may be my first project. Dirt simple to construct, but apparently a little more difficult to fine tune due to the flame front/flame tube needing to be well matched when the vanes close/open.

That's per unit... rather than the entire plant... so string more than one together on a site.. and viola...
Just for stupidity.. my Dad helped build most of the 1100MW twins in Illinois.. now he is helping bury one.

Jet engines! Even more awesome than sliced bread

I lived in Ithaca MI for about 15 years, the home of E. J. Potter. If you pick the right back road you can still see a few jet powered school busses and pull tractors. That man was SO far ahead of his time.

I have never bought a jeep that is as clean as the grand cherokee orvis edition we picked up for my wife's brother yesterday. Every bolt still looks like it came off the showroom floor. Simply amazing!! It was stored in an airplane hanger its entire life, only driven on the weekends. Pictures later today.
