SYSTEM FOR CHECK OF QUALITY OF LANDING OF FLYING VEHICLE Russian patent published in 1998 - IPC

FIELD: aeronautical engineering. SUBSTANCE: system includes sensor showing vertical deviation from standard trajectory and computer unit for determination of rate of this deviation which are connected to first input of permissible deviation analyzer whose command input is connected with sensor showing distance between flying vehicle and beginning of runway, its output being connected with indicator unit. According to invention, permissible deviation analyzer consists of multiplier unit, first comparison circuit, second comparison circuit, EXCELLENT and GOOD evaluation indicators and the following components connected in series: first multiplier, second multiplier, first switch, third multiplier, second switch, third comparison circuit, third switch and SATISFACTORY evaluation indicator. Special connection of circuits makes it possible to form quantitative estimation of accuracy of handling of flying vehicle in landing. EFFECT: enhanced accuracy of estimation of landing of flying vehicle. 2 dwg
