摘要:
针对飞机结冰问题,引入积冰程度参数的概念,定量地描述积冰强度,建立并将该参数引入到机体六自由度非线性积冰动力学仿真模型中。基于传统PID控制理论,设计了俯仰姿态保持模式闭环仿真系统。利用Simulink软件实现了某型飞机在积冰条件下的飞行动力学仿真,通过仿真,模拟了积冰对飞机主要飞行参数和操纵特性的影响。仿真结果表明,飞机的配平特性、操纵特性都受到积冰的严重影响,对飞行安全构成了严重威胁。
Abstract:
Aiming at the wing icing problem, the icing degree parameter was used to describe the ice effects on aircraft aerodynamic parameter; This parameters was introduced into nonlinear six degrees-of-freedom dynamic model of plane; A time-varying simulation model was established with Simulink, which varying with this parameter; By comparing the simulation result with flight test data, the correctness of this is verified; A pitch angle keeping model of closed loop simulation system is designed; In certain flight icing conditions, the open-loop and closed-loop flight simulation were performed; Through the open loop system simulation, studied the effect of ice accretion on aircraft trim characteristics, the flying state and the pilot response effect were also simulated; Through the closed-loop system simulation, the flight status affected by ice accretion processes and the corresponding response of aircraft control was simulated. The simulation results showed that the ice accretion has adverse effects on trim characteristics, aircraft response and automatic driving performance. It's a threat to flight safety.
