Featured aircraft
Our latest featured aircraft for May 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,

Although some of the images are repeated, the two sections serve different purposes. The first section aims to capture any image related to the aircraft, which could be aircraft, people, events, etc. The latter section only includes images selected specifically to highlight features of the aircraft.
