ADC Cirrus [SEP] manufacturer
ADC Cirrus
The ADC Cirrus and Cirrus-Hermes are British aero engines of the mid-1920s. Sometimes known as the Blackburn Cirrus, examples remain airworthy today.
Design and development.
ADC Cirrus engines were originally built by ADC Aircraft until Cirrus Aero Engines Limited was formed in 1927. The company became Cirrus-Hermes in 1931 when it was bought by the Cirrus-Hermes Engineering Company and later became the Cirrus Engine Section of Blackburn & General Aircraft Limited in 1934, and operated as a separate division until production ended in
various other light aircraft, trainers, liaison aircraft and air taxis, British as well as foreign, until long past World War II. Apart from helping to establish the de Havilland Aircraft Company as a manufacturer of light aircraft, it also established the company as an engine manufacturer in its own right.
Gipsy engines remain in service powering vintage light aircraft.
Design and development.
Just like the ADC Cirrus, the Gipsy was born as a collaboration between aircraft manufacturer Geoffrey de Havilland and engine designer Frank Halford. In
