Title:
AIRCRAFT
Document Type and Number:
WIPO Patent Application WO1989007073
Kind Code:
A3
Abstract:
An aircraft possesses two rotors (13, 14) driven by the engine, which drives the propeller simultaneously. By virtue of the fact that the tail plane is located entirely within the slipstream and that the ailerons and the landing flaps are located behind the rotor in the backwardly-directed airstream which flows over the rotor, optimal flight characteristics are achieved in conjunction with a V-shaped setting of the two rotors (13, 14).
