The Phoenix was an experimental version of the Bristol Aeroplane Company's Pegasus engine, adapted to run on the Diesel cycle. Only a few were built between 1928 and 1932, although samples fitted to a Westland Wapiti held the altitude record for diesel-powered aircraft at 27,453 ft (8,368 m) from 11 May 1934 until World War II.Gunston 1989, p.32. The primary advantage of the Phoenix was better fuel efficiency at cruise, by up to 35%.
Variants
- Phoenix I: Diesel version of the Pegasus IF, 380 hp.
- Phoenix IIM: Medium-supercharged diesel version of Pegasus IM, 470 hp.
