Has anyone managed to do this on a rotary or other auto setup using
  heat exchangers
     and liquid cooling. I have heard the old piston engine convairs used
  to
  use this as a
     way of 1) air cooling the engine very efficiently in a reduced cowling
  size, and 2)
     using the heat generated through combustion in the exhaust to generate
  some
     additional thrust,

     Anyone seen this done successfully

     They are called ejectors or augmenters.
     Yes its been done. I discuss this in my "Book How to Cool Your
  Wankel".

     Early Cessna 310 twin aircraft had similar, they had no cowl flaps,
     harder the engine worked the more air ejected via exhaust augmenters
  as
     Paul said, down side was they had no mufflers, by choice or if they
  did
     not work as well with mufflers I don't know.

  You might want to try Marc de Piolenc, he's writing a book on the
  subject.
  piolenc@archivale.com  he has a huge technical information service also
  specializing
  in stuff like this.

  thanks, i will follow up, rgds Alex molteno

  I had a 1956 Cessna 310 and i was flying in very cold weather in winter
  and warm in
  summer and never had problem without cowl flapsJean

 Hi all

 We raced the Norton Roatary and without the Exhaust ejector and Ram air we
 would not have been competitive, 588 cc twin rotor.

 Timed in international race North West 200 at 194 mph, this over 23 years
 ago.

 Won the British Championship and BBC Supercup, Won the TT in the IOM.

 See photos.

IOM aye,  where is the depression in the seat to accomodate the large
goolies required to win that race, crazy buggers, always makes good viewing.
Thanks Bob

What sought of power were you getting out of that machine?  and
what happened to the Norton Rotary, it obviously worked. Let me guess
they handicapped it out of existence. It would make a good alternative
engine for a midget mustang !!!!

The first paragraph was a real long line. The second wrapped. Strange!
Are you pressing the return key?
