“艾科尔斯”改进型光学助降系统的纵向着舰精度研究*

基于“艾科尔斯”(ICOLS:Improved carrier optical landing system)改进型光学助降系统的人工着舰系统是几种新型光电或激光舰载机助降系统之一,研究了“ICOLS”改进型光学助降系统的引导技术,整个系统的关键是引入激光束。研究重点是当航母在海浪、海涌干扰作用时,飞机在ICOLS系统引导下,人工操纵飞机着舰时的仿真结构配置,并导出终端误差方程。最后给出了在典型海浪作用下,ICOLS近程系统采用角稳定助降系统控制律的着舰精度仿真计算实例,从而为地面仿真研究着舰误差提供了基本思路与研究手段,对保证飞机安全着舰有十分重要的意义。

Research on Longitudinal Landing Precision for Carrier-Based Aircraft Based on "ICOLS" Laser Aided Landing System

Improved carrier optical landing system(ICOLS) developed by USA navy is one of the new photo-electricity or laser aided landing system.This paper studies the technique of ICOLS aided manual landing system.The characterize of this system is inletting laser beam.The keystone of this job is the simulation configuration allocation for the ICOLS aided manual landing system when it disturbed by wave and surf,and deduces the landing terminal error equations.At last,by using angle-stabilized control law it provides a simulation instance of the landing precision under wave and surf condition,so it provides a basic research way for landing error of shore-based simulation,and has a great meaning for ensuring safe landing of aircraft.
