Featured aircraft
Our latest featured aircraft for April 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,

What are Vertipedia Notes?
Vertipedia has been developed by a small team since the launch the project in Nov 2013. The purpose of the notes is to document and inform VFS members of the principles and processes used by Vertipedia. As always, the team does not claim to always have the best knowledge and where members have different views their feedback is welcomed. Note titles and descriptions are limited to 100 and 500 characters, respectively, to ensure that a note is concise and succinct.
