Bristol Phoenix

Phoenix
Type Diesel aircraft engine
Manufacturer Bristol Aeroplane Company
First run 1928
Major applications Westland Wapiti

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.[1] The primary advantage of the Phoenix was better fuel efficiency at cruise, by up to 35%.
