摘要
分析了起落架地面运动特点,研究了出现横侧运动时起落架受力特点,建立了一种可用于风场且能反映起落架总体特性的起落架数学模型。数值仿真了风场中飞机的起飞、着陆、滑行、转弯等地面运动。数值仿真结果表明,该模型基本合理,可有效地模拟飞机在风场中的地面运动特点,该模型可在飞行模拟器开发中使用。
This paper analyzes the characteristics of landing-gear ground motion, and studies the forces and moments on lateral motioned landing-gear, setting up a landing-gear mathematical model which demonstrates wheeled landing-gear＇s general characteristics and can be applied in wind-field simulation. Numerical simulations on take-off, landing, taxi and ground turning in wind-field have been done and results demonstrate that the model established in this paper is valid and logical on ground motion simulations,it can be further applied to simulator development.
