VTOL AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2000/005131
Kind Code:
A1
Abstract:
A VTOL aircraft comprising propellers (1, 2) located at the front and rear of a main wing (3), the front propeller (1) being provided so that it pulls an airframe forward and a back wash by the propeller (1) provides a lift to the main wing (3), and the rear propeller (2) being provided so that the back wash by the rear propeller is directed toward the trailing edge of the main wing (3) in order to raise the airframe, and prevent a lift efficiency from being lowered due to separation of the back wash by the front propeller (1) from the upper surface of the main wing (3) ranging from near the center to the trailing edge so as to provide a big lift.
