METHOD OF PREVENTION OF COLLISION OF FLYING VEHICLE WITH GROUND AND DEVICE FUNCTIONING ON BASIS OF THIS METHOD

摘要

FIELD: systems for ensuring safety flights for various flying vehicles.;SUBSTANCE: proposed method includes determination of flying vehicle position by means of navigational system and parameters of present dynamic state, calculation of predicted trajectory, comparison of predicted trajectory with relief of terrain, determination of dangerous relief and giving warning on danger. Prior to comparison of predicted trajectory with relief of terrain, minimum permissible radii of turn are continuously calculated on basis of parameters of present dynamic state after which radii of turn are predicted during determination of dangerous relief and predicted trajectory is compared with relief of terrain by scanning the space in the corridor safe for the said trajectory. Boundary of safe corridor is determined on the assumption of possibility of turning the flying vehicle to reciprocal heading in accordance with predicted magnitudes of minimum permissible radii of turn. Dangerous relief is determined on basis of comparison of predicted trajectory with relief of terrain. Device functioning on basis of this method is provided with calculators of minimum permissible radii of turn at present moment and predicted for preset time, safe corridor former and comparator scanning unit for comparison of safe corridor with relief of terrain.;EFFECT: enhanced safety of navigation.;4 cl, 5 dwg
