SUD OUEST SO1221 DJINN
Title: Sud Ouest SO1221 Djinn
The SO1221 Djinn was a small two-seat light turbine helicopter notable for its unusual propulsion system. The turbine engine was used to produce compressed air which was fed to outlets at the ends of each blade. This method of propulsion had the benefit of not requiring an anti-torque system such as a tail-rotor. The aircraft first flew in 1953 and was produced until the early 1960’s by which time 178 had been built. The main operator was the French military, but three examples were evaluated by the US Army as the YHO-1. (This is probably the reason manuals were produced in English.)
This title contains two manuals for the SO1221, a descriptive and operation manual and a technical manual which includes flight manual data, plus a brochure. The files have been scanned from the original flight manuals and retain any colour pages.
