| 摘 要： | 结冰条件下运输类飞机的适航审定是确保飞行安全的重要保障.建立了飞机本体非线性动力学模型和不同状态的结冰模型,计算了结冰前后飞机对驾驶员控制输入指令的响应特性,并探讨了结冰对飞机爬升性能的影响.仿真结果表明,结冰会导致舵面操纵效率下降,从而引起动态响应特性的恶化,而且飞机出现不对称结冰时将严重偏离正常状态、危及飞行安全,...

| Abstract: | Airworthiness certification for transport category aircraft under icing conditions is an important safeguard to ensure flight safety.Together with a six degree-of-freedom computational flight dynamics model,two different icing effect models are developed to study the effects of ice accretion on sensitivity of dynamic response to pilot command inputs,and the aircraft climb performance between clean and iced aircraft are also explored.Based on the results presented in the paper,it is concluded that the icing ... |
