地面效应对FCLP训练接地误差影响的仿真分析

Simulation Analysis of Influence of Ground Effect on Grounding Error in FCLP Training

基于地面效应对飞机近地面飞行影响的空气动力学机理,以舰载机FCLP训练下滑段为基准运动,建立纵向小扰动方程,将地面效应影响化为扰动输入,对FCLP训练中地面效应引起的误差进行仿真分析,并结合此阶段飞行员的操控特点,讨论了减小地面效应影响的措施。本文对精准安全的舰基飞行训练具有借鉴意义。

Based on the aerodynamic mechanism of the influence of ground effects on aircraft near ground flight,a longitudinal small disturbance equation is established by taking the motions on the gliding line of ship-based aircraft FCLP training as the reference,in which the ground effect is transformed into disturbance input,and the errors caused by ground effects in FCLP training are simulated and analyzed.Combined with the control characteristics of pilots in this stage,measures to reduce the influence of ground effects are discussed.This paper has reference significance for precise and safe ship-based flight training.
