METHOD FOR PREVENTION OF UNAUTHORIZED USE OF FLIGHT VEHICLES Russian patent published in 2004 - IPC

FIELD: engineering engaged in development of vehicle-borne equipment and onboard systems of flight vehicles providing flight safety and safety of ground objects of very importance at an unauthorized use of the flight vehicles by an evil-wisher. SUBSTANCE: the method consists in the fact that in the process of pre-flight action program trajectory parameters are entered in the on-board control system of the flight vehicle, in the process of flight mismatching between the real and program trajectory parameters of flight is revealed by air-borne, ground, air and space aids, conflicting-dangerous flight vehicles are revealed according to their energy potential and the degree of importance of the objects located along the flight route or in the zone of the reached range. At an unauthorized appearance of the mentioned mismatching by a value exceeding the preset one the above aids produce and transmit to the board commands for reconfiguration of onboard systems and/or vehicle-borne equipment. These circumstances make the pilotage of the flight vehicle difficult and discomfort at its pilotage is created, which may cause a refusal from the authorized intentions. EFFECT: prevented premediated doing of irretrievable damage to very important objects by the "komikadze" method by a flight vehicle caught by force by terrorists by creation of conditions on the board of the vehicle preventing a change of the preset flight path of the vehicle hampering the pilotage of the flight vehicle, preventing aimed guidance of the flight vehicle to the selected object. 1 dwg
