SUPERLIGHT UNMANNED FLYING VEHICLE Russian patent published in 2007 - IPC B64C39/10 B64C25/32 

FIELD: aerodynamic unmanned flying vehicles.

SUBSTANCE: proposed flying vehicle has central coupling unit which is elongated longitudinally; rear part of coupling unit is provided with controllable impeller and payload compartment is located in nose section. Wings of unmanned flying vehicle are secured to side surfaces of central coupling unit and are oriented perpendicularly relative to longitudinal axis of central coupling unit; they lie in one horizontal plane. Alighting gear absorbs kinetic energy of flying vehicle at contact with ground surface, at collision in flight with other flying vehicles and movable and fixed objects. According to one version, alighting gear consists of first and second protective hoops which are identical in form and sizes and are located respectively in horizontal and vertical planes and are rigidly secured at points of intersection. External tips of flying vehicle wings are secured on diametrically opposite segments of first protective hoop. Upper and lower points of second protective hoop are connected with central coupling unit by means of dowel pins. Central coupling unit is made from carbon-reinforced or glass-reinforced plastic; wings are made from strong synthetic material, polyethyleneterephthalate (lavsan) and hoops and dowel pins are made from rigid elastic material, carbon-reinforced plastic for example.

EFFECT: enhanced efficiency of protection at landing and in flight in case of collision with other flying or fixed objects.
