snips...

 Very interesting indeed.  With a range from 700 hp (non turbo) up to 1600
 hp (turbo compound) the Wankel could compete with the PT 6 with propeller:
  probably less expensive, lighter and consuming less. The disadvantage of
 TBO  (2000hrs. against 6000) could be compensated by the lower price of
 parts and labour in favor of the Wankel.  Am I not too optimistic ?  EB.


Those that may not be aware the Fairy Rotodyne had 40 passenger service
between Paris and London, weighing 33,000lbs it had two 2,800shp turbine
engines, 59ft. fuselage, 46ft. wide wings, with two tractor mounted four
bladed propellers, vertically capable 60ft. four bladed autogyro rotor able
to auto-rotate in power out landings, the rotor blade tips had jets to power
normal landings.

What about a Wankel powered version, slide in a few more rotors in the
monster wankel design you have 2,800 hp???

A more aerodynamically efficient configuration is the V22.

Paul,

If the Bell 609 EVER becomes available, the engine shp of the 609 is
compatable with this "monster engine".

Here is the specifications from the net:

Engine Model    Pratt & Whitney Canada PT6C-67A
Engine Power (each)    1445 kW    1938 shp

Looks like a good match to me.
