Abstract

1,093,720. Aircraft fitted to the person. E. UHOR. Dec. 11, 1964, No. 50516/64. Headings B7G and B7W. An aircraft for direct attachment to the body of a pilot comprises a forward housing section 14 for removably receiving the upper portion of the pilot, a rear tail leg supporting section 16 connected by a hinge pin 38 to the housing section 14, a pair of foldable wings 70 mounted on the housing section 14, and control surfaces on the wings and tail operable by an axially and rotatably movable control stick 86 and by footoperated levers. The aircraft is powered by propellers mounted on the wings and when not required for use it can be folded and carried on the pilot's back. To fold the aircraft latches 52 are released and the tail section 16 is folded up to the pilot's chest and an undercarriage 254 locked to a chest plate 30 is pivoted to a position overlying the shoulders of the pilot, Fig. 5 (not shown). Each wing 70 is mounted on a shaft 68 rotatable in a cross-bore provided in a shaft 64 capable of being rotated by bevel gears 111. If the wings are to be moved to their folded position a lever 116 is operated whereby the bevel gears 111 on the ends of the shafts 64 are rotated through gears 114, 115 and a coupling shaft 112. To enable the folding operation to be performed the shafts 64 are provided with jaw clutches 317 arranged to be engaged by a cam mechanism, Fig. 17 (not shown), automatically operated by rotation of shafts 64. The cam mechanism is also arranged to disengage bevel gears 120, 128 from engagement with bevel gears 117 freely rotatable on the shafts 64 and in constant mesh with the gears 110 fixed to the wing shafts 68. The clutches are arranged to be engaged one after the other so that the shaft 68 of one wing is first rotated about its own axis whereby one wing overlies the other when folded. The shafts 68 are also rotatable in order to change the inclination of the wings for horizontal or vertical flight. A lever 121 is provided for this purpose, the lever operating through bevel gearing 120, 117, 118, a transverse shaft 119 and further bevel gearing 128, 117, 110. A spur gear mounted on the transverse shaft 119 is arranged to cause simultaneous movement of a rack along a slide 130, the rack causing pivoting of the tail section through gear and cable linkage. A mechanism for causing locking of the rack or movement thereof in the opposite direction for reverse pivoting of the tail with respect to the wings is provided. Thus operation of the lever 121 is capable of simultaneously pivoting, in the same or opposite direction, the wings and tail section for enabling vertical and horizontal take-off, landing and flight. The tail section 16 comprises a pair of tail members 192 (one for each leg of the pilot), from each of which extends at right-angles thereto a foot-operated rudder. Each tail member has a large wheel 246 for use during conventional take-off and landing and a smaller wheel 242 for assisting during vertical take-off or landing.
