Our latest featured aircraft for September is the Cierva W.11 Air Horse .
The aircraft was designed to provide viable heavy load lifting capability for commercial operations. It employed 3 main rotors all rotating in the same direction. Torque offset was provided by thrust components from the 3 rotors through built-in shaft tilt. The aircraft had a semi-monoquoque structure, a single engine, and a long-stroke undercarriage (5ft) to cope with high rates of descent. A description of the aircraft and its characteristics can be found in the following references,
