Bristol Phoenix

The Phoenix was an adaptation 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 planes from 1934 until WWII. The primary advantage of the Phoenix was better fuel economy at cruise, up to 35%.
