Patent ID: 7410121

Claim:
A man-powered ornithopter-sailplane with a muscular propulsion engine, which is connected through a kinematic chain to one or two pairs of flapping wings, and characterized in that posterior wing axle ball joints ( 15 , 16 ) of horizontally inclined wing axles ( 13 , 14 ) for the flapping wings are directly connected to posterior upper corners of a frame, which comprises of strips ( 8 , 9 , 10 , 12 ) and is attached to a torso base ( 1 ) for a femoral propulsion engine, and in that aft of posterior wing axle ball joints ( 15 , 16 ) are wing axle brackets ( 30 , 31 ), which comprise an extension of wing axles ( 13 , 14 ), between ends of which wing axle brackets ( 30 , 31 ) is stretched cord ( 32 ), a counterbalance of which comprises of a cord ( 33 ) stretched between mobily attached anterior wing axle ball joints ( 17 , 18 ) of wing axles ( 13 , 14 ), which joints receive guiding movements through wing axle ball joint to shoulder ball joint intermediate links ( 19 , 20 ) and shoulder ball joints ( 21 , 22 ) from humeral arms ( 23 , 24 ) of a humeral propulsion engine, arms of which are firmly attached with elastic straps ( 28 , 25 , 26 ) respectively to upper arms, between themselves, and to a shoulder base ( 7 ), which last is joined by sliding torso ball joint ( 6 ) to said torso base ( 1 ), which is attached by joints ( 5 ) to femoral arms ( 3 ), which are directly joined kinematically through femoral arm attached ball joints ( 34 , 35 ), femoral arm attached ball joint to wing arm ball joint intermediate links ( 36 , 37 ), wing arm ball joints ( 38 , 39 ), and wing arms ( 40 , 41 ) to flapping wing panels ( 42 , 43 ) as well as to rotatable stiff rods ( 44 ) mounted in them and stiff aerodynamic feather-like panels ( 45 ), which are attached to the rods asymmetrically to rods' axes and which form the general effective aerodynamic profile of the middle and end of the flapping wing.
