The "high G's" and "supersonic speeds" have NOTHING to do with the high cost 
of turbine blades. They get plenty of G loading and supersonic speeds while 
the engine is on the ground. The amount of G loading from in flight actions 
are nothing compared to the normal road shock the engine would see anyway. 
 MR> The blade assembly is cast in one solid piece. 
Cast as one piece? On what engine? They have a high enough reject rate now on 
single blade casting when x-ray inspected that I would hate to see what the 
reject rate would be on a one piece casting.

What kind of waste of power will this cause? I would suspect a fairly large 
one.

It is not really that different of an application. About the only differences 
are the exhaust has to be managed, the load will be constant, and the intake 
air will have to be filtered.

I have no prejuices against turbines. I do have experience with them. I have 
NOT just read about them in a book or magazine. They are simple in basic 
design BUT they are very exotic in materials.
