Vertipedia is a product of the Vertical Flight Society. With data on 859 aircraft, 612 historical milestones, 472 people, and 392 organizations, Vertipedia is your "one-stop shop" for all things vertical lift.
Our latest featured aircraft for August 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,

Aircraft and Type resource searches
For each aircraft and Type there is an automated search of available resources (documents, etc.). In most cases these automated searches produce a range of useful results. In some case the results may include many that are not relevant. This is because the aircraft or Type designation includes a common word (e.g. Model). It is difficult to define an algorithm that will counter this issue. The user can always use the configurable search from the menu bar for better results.
