Featured aircraft
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,

Level of detail in entries
Vertipedia sometimes lacks detail supporting a particular entry. Primarily, this is because Vertipedia data is built using a 'top-down' approach where details are expanded over time. This allows us to more quickly capture breadth as well as depth of data. The depth of data is particularly related to the number of contributors. Please contact the Vertipedia team if you think that you can help.
