METHOD OF LANDING UNMANNED AERODYNAMIC FLYING VEHICLE Russian patent published in 2006 - IPC B64C29/02 B64C25/40 

FIELD: landing unmanned aerodynamic flying vehicles.

SUBSTANCE: prior to flight, electronic guidance equipment is mounted on board and ground landing equipment is placed on landing field. Horizontal flight and landing approach are carried out in aircraft mode with the aid of satellite radio navigational system. At final landing section, self-guidance of flying vehicle on landing field is performed by means of on-board electronic guidance equipment and ground landing equipment with the aid of one algorithms of correlation extremal navigation; soft landing is carried out by killing the kinetic energy of flying vehicle motion. Specific feature of proposed method as compared with known methods consists in decreasing flight speed after beginning of self-guidance of flying vehicle on landing field by means of power plant and aerodynamic control members and increasing angle of attack to critical magnitudes ensuring auto-rotation of flying vehicle at precession relative to direction of speed vector of its translational motion. Then, speed of its vertical motion relative to Earth is reduced by means of aerodynamic control members of flying vehicle to magnitudes ensuring complete killing of kinetic energy and soft landing on landing field.

EFFECT: possibility of landing super-light unmanned flying vehicle without complex expensive equipment.
