Our latest featured aircraft for October 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,

How are 'Featured Aircraft' chosen?
The 'Featured Aircraft' in Vertipedia is usually chosen to highight the depth of data that can be available for a particular aircraft. We try to choose an aircraft that should be interesting to a wide range of users of the database. To this end, we generally cycle between historic or current aircraft but we also occasionally highlight aircraft that may be of interest to a smaller community. We try to change the aircraft on a monthly basis but there is no set period.
