Design and development

The Serval was a ten-cylinder, double-row, air-cooled radial piston engine. It was developed from the Armstrong Siddeley Mongoose and was, more or less, two Mongooses built around a single crankcase. In fact, it first appeared as the Double Mongoose in May 1928. [1]

Built in several variants, power output was about 340 hp (254 kW).

Developed in the mid-1920s it was used in the Hawker Tomtit trainer and Parnall Peto seaplane amongst others. With a displacement of 540 cubic inches (9 litres) the Mongoose had a maximum power output of 155 horsepower (115 kilowatts).

Armstrong Siddeley Genet Major 1920s British piston aircraft engine

The Armstrong Siddeley Genet Major is a British five-cylinder, air-cooled, radial engine for aircraft, designed and built by Armstrong Siddeley and first run in 1928. It developed 140 horsepower (104 kW). In Royal Air Force use the seven-cylinder version was known as the Civet I. The Feliform names used are in line with company convention, the Genet and Civet both being large cat-like carnivores.

Armstrong Siddeley Genet 1920s British piston aircraft engine

The Armstrong Siddeley Genet was a five-cylinder, air-cooled, radial engine for aircraft use built in the UK, first run in 1926. It developed 80 hp at 2,200 rpm in its final form and was a popular light aircraft powerplant. Following the company tradition with a slight deviation the engine was named after the Genet, a catlike animal of the same order but different family.

It proved, however, to be extremely unreliable and was abandoned when its faults were unable to be corrected.

Armstrong Siddeley Ounce 1920s British piston aircraft engine

The Armstrong Siddeley Ounce was a small two-cylinder aero engine developed by Armstrong Siddeley in 1920. The engine was originally conceived as a test piece but ran very well and was put into production for early ultralight aircraft and use in target drones. The Ounce used two cylinders from the preceding Jaguar I radial engine.

Bristol Neptune 1930s British piston aircraft engine

The Bristol Neptune was a seven-cylinder air-cooled radial engine developed in 1930. It had the same size cylinders as the earlier Mercury and Titan engines, 5.75 in (146 mm) x 6.5 in (165 mm) which gave a displacement of 1,182 cu in and produced a maximum of 320 horsepower (239 kW). The Neptune was effectively a seven-cylinder version of the Titan.
