Welcome to Vertipedia!
Vertipedia is a product of the Vertical Flight Society. With data on 865 aircraft, 620 historical milestones, 542 people, and 395 organizations, Vertipedia is your "one-stop shop" for all things vertical lift.
Featured aircraft
Our latest featured aircraft for June 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,

Vertipedia Notes
Vertipedia notes are brief descriptions of how and why Vertipedia works the way it does. Check back often for the latest note, or view the complete list.
Classification of milestones
Milestones are classified by the type and importance of the event. The type of event provides an objective view of the context for the event whist the importance is a subjective view its importance to VTOL history. Both are determined by the contributors to Vertipedia but the latter will always be subject to discussion and debate, which is welcomed through direct participation in Vertipedia or by contacting the Vertipedia team.
