The Blackburn Cirrus Major is a British, four-cylinder, inline aircraft engine that was developed in the late 1930s.

Design and development

The Blackburn Cirrus Major started life as a development of the original ADC Cirrus series of aircraft engines which progressed through a number of variants, each with slightly different displacement and power outputs. The Cirrus series was later bought by Cirrus Aero-Engines (later known as the Cirrus-Hermes Engine Company) which produced the Cirrus Hermes I, II, III and IV, again each differing slightly in displacement and power.

In 1934 Cirrus was bought again by the Blackburn Aircraft company and later that year the Cirrus Minor was produced. In 1935 the Cirrus Major entered production.
