| | 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.
