METHOD OF LANDING FLYING VEHICLE Russian patent published in 2003 - IPC

FIELD: methods of landing unmanned flying vehicles. SUBSTANCE: proposed method includes mounting pulse ration source on flying vehicle. Vertical swivel frame, two pulse radiation receivers, vertical landing net for horizontal motion over guides, computer and deceleration device are mounted on platform in landing point. At final section of landing approach, flying vehicle is brought to active zone of receivers for measurement of angular altitude and lateral displacement of flying vehicle relative to center of said axis. Then, deflection of flying vehicle from programmed trajectory of flight is calculated and flight trajectory is corrected for entering the net. After flying vehicle is received by net, it is moved over guides of frame and kinetic energy of motion is dampened due to pulling ropes of deceleration device. Novelty of invention consists in position of platform which moves in way of horizontal axis perpendicular to plane of net and mounting additional linear acceleration sensor, range finder and sensor of beginning pulling ropes of deceleration device. At final section of landing approach, present range to landing point and required acceleration of translational motion of frame are calculated. EFFECT: enhanced safety of landing under difficult weather conditions. 2 dwg
