Bristol Phoenix

From Wikipedia, the free encyclopedia

The Bristol Phoenix is also the name of the newspaper of Bristol, Rhode Island.

The Phoenix was a 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 planes from 1934 until World War II. The primary advantage of the Phoenix was better fuel efficiency at cruise, by up to 35%.
