Vertipedia is a product of the Vertical Flight Society. With data on 862 aircraft, 613 historical milestones, 474 people, and 393 organizations, Vertipedia is your "one-stop shop" for all things vertical lift.

Our latest featured aircraft for November 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 Types, Variants and Versions

The aircraft module in Vertipedia assumes a Type/Variant/Version structure for aircraft from the same family (or series). In many large programs the manufacturer uses this type of structure (possibly using different terms) to develop a range of different versions for different customers. A version normally defines an aircraft for a specific operator. A specific aircraft can only be assigned to one Type and Variant. Aircraft do not have to be assigned to a Type or Variant.

Vertipedia makes it easy for you to find a range of information on vertical flight, including:

  • Targeted searches of documents provided by the Vertical Flight Society, as well as public sources from across the internet
  • Important milestones that have helped shape the history of vertical flight
  • People who have played a role in vertical flight
  • Vertical flight aircraft, such as helicopters, tilt rotors and tilt wings, jet-lift VTOL, and more.
