| | The Bristol Mercury Aircraft Engine | Roy Fedden designed the Bristol Mercury nine-cylinder air-cooled radial piston engine in the early 1920's. The Bristol Mercury was based on the earlier Bristol Jupiter engine but with considerably increased performance, when first run in 1925 the Bristol Mercury produced 420 hp, late supercharged variants produced 870 hp. By the end of production well over 20,000 Bristol Mercury engines had been produced including licence built engines in Poland, Sweden, Italy and Czechoslovakia |
