Attribution

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,

Map locations for milestones

The aim is to provide an exact location for each milestone in the database. In many cases this is not possible and all we can provide is the nearest possible, general location (usually a town instead of a specific location). The map view provided is normally chosen to provide detail of the location as well the general area to provide overall geographical context. We always welcome feedback on the accuracy of the map locations provided.

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.
