The Bristol Jupiter Aircraft Engine
The Bristol Jupiter was designed by Roy Fedden for the Bristol Aeroplane Company at the end of WW1 first run in October 1918. The Bristol Jupiter proved to be a great success and was the best, and most sold, radial aero-engine in the between war period. Although Bristol was the main producer of the engine it was also produced in great numbers under licence, Gnome-Rhone in France, Siemens-Halske in Germany, Nakajima in Japan, PZL in Poland, Alfa Romeo in Italy, Walter Engines in Czechoslovakia and Shvetsov in Russia.
Production finally ceased in 1930 by which time at least 7,100 had been produced, the engine was then significantly re-designed and developed into the Bristol Mercury. The engine pictured above is a 550 hp Bristol Jupiter IXF. At the end of Jupiter production over 260 aircraft types had been powered by the Bristol Jupiter including licensed copies and over 80% of all aircraft at the 1929 Paris air-show were powered by the Jupiter.
