Blackburn Cirrus Midget
The Blackburn Cirrus Midget was a British four-cylinder, inverted, in-line air-cooled aero engine designed and built in 1937 by the Cirrus Engine Section of Blackburn Aircraft Limited. Little is known of its development and use, its sole aircraft application is reported as the Chilton D.W.1 although it is possible that this did not transpire.[1][2]
