Type Piston aircraft engine

Manufacturer Bristol Aeroplane Company

Designed by Roy Fedden

First run 1925

Major applications Bristol Blenheim Gloster Gladiator

Number built 20,700

Developed from Bristol Jupiter

For the 1917 14-cylinder radial engine see Cosmos Mercury

The Bristol Mercury is a nine-cylinder air-cooled single-row piston radial engine . The Mercury was used mainly on British military aircraft in the 1930s and1940s. A number were also built in Europe under licence.

At least two Bristol Mercuries remain airworthy in 2010.

Design and development

The Mercury was developed by the Bristol Aeroplane Company in 1925 as their Bristol Jupiter was reaching the end of its lifespan. Although the Mercuryinitially failed to attract much interest, the Air Ministry eventually funded three prototypes and it became another winner for the designer Roy Fedden .

With the widespread introduction of superchargers to the aviation industry in order to improve altitude performance, Fedden felt it was reasonable to use asmall amount of boost at all times in order to improve performance of an otherwise smaller engine. Instead of designing an entirely new block, the existingJupiter parts were re-used with the stroke reduced by one inch (25 mm). The now-smaller capacity engine was then boosted back to Jupiter power levels, whilerunning at higher rpm and thus requiring a reduction gear for the propeller . The same techniques were applied to the original Jupiter-sized engine to produce thePegasus .

The Mercury's smaller size was aimed at fighter use, and it powered the Gloster Gauntlet and its successor, the Gloster Gladiator . It was intended that the largerPegasus would be for bombers , but as the power ratings of both engines rose the Mercury found itself being used in almost all roles. Perhaps its most famoususe was in a twin-engine light bomber , the Bristol Blenheim .

In 1938 Roy Fedden pressed the Air Ministry to import supplies of 100 octane aviation spirit from the USA. This new fuel would allow aero engines to run athigher compression ratios and supercharger boost pressure than the existing 87 octane fuel thus increasing the available power. The Mercury XV was one of thefirst British aero engines to be type-tested and cleared to use the 100 octane fuel in 1939. This engine was capable of running with a boost pressure of +9

lbs/sq.in and was first used in the Blenheim Mk IV .[1]

The Mercury was also the first British aero engine to be approved for use with variable pitch propellers.The Bristol company and its shadow factories produced 20,700 examples of the engine .[2]

Outside the United Kingdom, Mercury was licence-built in Poland and used in their PZL P.11 fighters. It was also built by NOHAB in Sweden and used in theSwedish Gloster Gladiator fighters and in the Saab 17 dive-bomber. In Italy, it was built by Alfa Romeo as the Mercurius. In Czechoslovakia it was built byWalter Engines ,
