PERSONAL AIRCRAFT Russian patent published in 2011 - IPC B64C29/00 

FIELD: transport.

SUBSTANCE: invention relates to aviation, more specifically to personal aircraft. The craft contains tube frame with landing skid and pilot seat, engine, coupling clutch, vertical lift propellers, control mechanisms. The propellers represent two vertical cylinder bodies installed at sides of tube frame. Inside each propeller, reducing gear with vertical driven shaft and upper and lower disks fixed on the vertical shaft are mounted. On the upper surface of each disk, fins are installed which have height of 15-20 mm and form concentric channels where narrow and wide sections are interleaving. On the lower surface of each disk there are blind radial channels of rectangular cross-section which channels taper towards the center and longitudinal axis of each of them makes an angle with vertical plane, and inlets are faced in rotation direction. Driving shafts of vertical lift propellers are kinematically connected via double tapered differential with drowned brakes, tapered gear train of contra-rotation of vertical lift propellers disks and coupling clutch with combustion engine. In the rear part of the frame, vertical stabiliser with rudder is mounted which stabiliser is linked with foot pedals by means of cables and blocks. To perform fore-and-aft trim of aircraft the pilot seat moving mechanism is located in the front part.

EFFECT: simplification of aircraft structure and increase in safety.
