NR642: 90 bhp from 60 kg total weight with integrated reduction gearbox.
Twin rotor by 294 cc gives 588 cc. At cruise, Specific fuel
consumption (SFC) of 0.51 lb / bhp per hour. Uses leaded or unleaded,
Avgas or Mogas fuels. In field trials, 1989, when it was chosen by
the joint McDonnell Douglas / Development Sciences Corporation team as
the best engine for short range Remote Piloted Vehicles (RPV).
This engine was approved by the CAA for civilian passenger aircraft in
December 1990. During testing, the engine is run for 150 hours at
8000 rpm, disassembled, reassembled and run again for 150 hours. This is
like driving at a constant speed of 120 miles per hour for 35,000
miles with only one stop.
In 1990 Norton contracted Rogers Aviation in Cranfield, England, to
install a Cessna 152 with an NR642 for testing. One was powering a
Seabird Sentinel pusher prop light aircraft in 1989. Two were in an Ivan
Shaw TwinEze, cruising speed 175 knots, two pusher props of 53
in diameter. Ivan Shaw was GM of Aviation Composites Ltd, a former branch
of the Lotus car company.
NR622: similar to NR642, but has a lower prop line and a lighter gearbox.

the monito.com site contains much more about rotary aircraft engines.
MWE can be found at http://www.monito.com/wankel/mid-west-eng.html.
There's also a short section on Wankel Rotary GmbH in Germany which
have recently marketed small aircraft rotaries. I suggest that you
just look at http://www.monito.com/wankel/ and see the whole site on
rotaries.
Hope this helps,
Roland
