ABSTRACT:
A man-powered ornithopter-sailplane, which has one or two pair of flapping wings and a hang-glider wing wherein substantially novel femoral and humeral muscular propulsion engines with the aid of which the body members connected thereto form integrated moving-flying and controlling-guiding mechanisms. Femoral arms are fixed to the torso base from which the movements for the wings flapping with respect to axles inclined to a horizontal direction are transmitted through the intermediate links of a kinematic chain. The wings comprise a row of rotational rods arranged therein and provided with elastic feather-like panels which produced during flapping, in a closed or turned position thereof, aerodynamic profiles and corresponding lifting and propulsion aerodynamic forces. The controlling-guiding movements are transmitted from the humeral arms to the flapping wings using movable ball joints. The diversity of movements of the femoral arms, humeral arms, hang-glider wing make it possible to control the flight.
