Summary

 
Object and purpose of research. This paper studies optical landing aid system of carrier airplanes and its control law. The purpose of this work is to develop control & stabilization law for the optical landing aid system to ensure smoother touchdown and, accordingly, safer landing of airplane on a moving carrier deck. This control & stabilization law is based on prediction algorithms for ship motions at the moment of touchdown. These algorithms must be applicable directly in the process of a real aircraft landing onto carrier deck
Subject matter and methods.Motion predictions are obtained through regressive analysis of time series, a common tool of random-process theory. Applicability of prediction algorithms is estimated by simulation (at TsAGI PS-10M flight simulator) of carrier aircraft landing assisted by the optical aids.
Main results. This paper suggests a control law for optical landing assistance tools of carrier aircraft that predicts deck position at the moment of touchdown while the aircraft descends along a pre-set path. The simulation performed at PS-10M flight simulator of TsAGI has shown that control law suggested in this paper enables considerably smoother landing than standard control of optical landing aids.
Conclusion. The results of this work are intended to improve the accuracy of manual (i.e. optical aid-guided) landing of carrier aircraft onto a moving carrier deck, i.e. to enhance operational safety of carrier aviation.
