This Cirrus aero engine was made in 1942 by Blackburn Aircraft Ltd of Yorkshire. It powered a Taylorcraft Auster I light aircraft used by the RAF for communications.
The engine was operated inverted to provide a good forward view for the pilot. It is a four-cylinder in-line, air-cooled engine of 3.6 litres capacity. It developed 90 horsepower at 2600 rpm.
The Cirrus-type engine was designed by Frank Halford from a single bank of the Renault Vee-8 engine. It was originally built by the Aircraft Disposal Company in 1925 and was known as the Airdisco Cirrus. In 1934 the manufacture of the engines was taken over by Blackburn Aircraft Ltd.
