![]() The powered hang glider of claim 2 wherein said keel has secured thereto, near said propeller, a split pillow block for a second bearing means in which said propeller shaft is rotatably held at an angle, slightly less than 5° from the longitudinal axis of said hang glider. (v) mounting means for mounting said engine in said air frame, fore on said elongated members, that is, in front of said positioning means.ģ. ![]() (iii) a reduction mount removably secured to said engine, for mounting said first bearing means in transversely spaced apart relationship with said engine so that the longitudinal axis of said first bearing means is no further than 25.4 cm from the axis of rotation of said crankshaft, said propeller shaft being slightly offset at an angle less than 5° from said longitudinal axis, In a powered hang glider of the single wing category having a longitudinal axial keel, which hang glider is foot-launched by a single occupant for flight in the cruising speed range from about 25 miles per hour (mph) to about 35 mph, and foot-landed at the end thereof, comprising an air-frame and a two-cycle internal combustion engine mounted in said air-frame which includes an occupant positioning means supported for flight by at least one wing member, and said positioning means includes at least two elongated members symmetrically disposed about a vertical plane through the longitudinal axis of said hang glider, the improvement comprising,Ī reduction drive unit drivingly engaging said engine which operates in the range from about 5000 rpm to about 10,000 rom, with a fixed pitch relatively large diameter propeller having a pitch in the range from about 9 ins to about 16 ins and a diameter in the range from about 0.9 meter to about 1.4 meters, said reduction drive unit including: (v) mounting means for selectively mounting said engine in said air frame, fore or aft on said elongated members of said positioning means.Ģ. (iv) driving means for drivingly engaging said small drive means and said large driven means so as to rotate said propeller in the range from about 2500 rpm but less than 5000 rpm, and (c) a bearing housing for said first bearing means for said propeller shaft, said bearing housing extending downwardly from said platform member to support said propeller shaft offset less than 5° from the longitudinal axis of said hang glider, (b) aligned oppositely disposed stub mounts fitted with vibration damping means between said mounting means and said elongated members, and between said mounting means and said reduction mount, to damp vibrations of said engine and said propeller, said stub mounts extending from said platform, (a) a platform mounting member directly secured to said engine, ![]() (iii) a reduction mount removably secured to said engine, for mounting said first bearing means in transversely spaced apart relationship with said engine so that the longitudinal axis of said first bearing means is no further than 25.4 cm from the axis of rotation of said crankshaft, said propeller shaft being slightly offset at an angle less than 5° from said longitudinal axis, wherein said reduction mount comprises, (ii) a relatively large driven means fixedly disposed for rotation with a propeller shaft mounted for rotation in a first bearing means, (i) a relatively small drive means fixedly disposed near one end of the crankshaft of said engine, In a powered hang glider which is foot-launched by a single occupant for flight in the cruising speed range from about 25 miles per hour (mph) to about 35 mph, and foot-landed at the end thereof, comprising an air-frame and a two-cycle internal combustion engine mounted in said air-frame which includes an occupant positioning means supported for flight by at least one wing member, and said positioning means includes at least two elongated members symmetrically disposed about a vertical plane through the longitudinal axis of said hang glider, the improvement comprising,Ī reduction drive unit drivingly engaging said engine which operates in the range from about 5000 rpm to about 10,000 rpm, with a fixed pitch relatively large diameter propeller in the range from about 0.9 meter to about 1.4 meters, said reduction drive unit including:
