货物在货舱内移动时飞机动态特性的研究

本文根据理论力学和飞行力学的基本原理,对货物在飞机货舱内移动时飞机和货物的运动方程作了详细推导.并对牵引伞的牵引力,约束反力的确定进行了探讨.得出了一些有益的结论.并以Y—8飞机为例,对牵引伞的牵引比、空投速度、空投高度、空机和货物重量、空投货物装置位置和操纵规律等各种田素以及空投操稳特性进行了分析研究.

THE STUDY ON THE DYNAMIC CHARACTERISTICS OF AIRCRAFT WITH CARGOS MOVING IN ITS CARGO CABIN

The kinematic equations of aircraft and its cargos moving in the cargo cabin are derived in detail based on the basic principles of theoretical mechanics and flight dynamics. And the determination of the tractive force and the binding force for the towing parachute are discussed, obtainning somt usful conclusions. As an example, an analysis study is under-token on several factors affecting Y-8 aircraft dynamic characteristics such as the traction ratio of towing parachute, the air speed and altitude for airdropping, the weight of empty aircraft and cargo, the cargo installed position on the aircraft, the control regulations etc, and the aircraft controllability and stability for airdropping.
