一类可变飞行模态飞行器的统一建模研究

可变飞行模态飞行器,兼有直升机垂直起降、悬停和固定翼飞机高速前飞的优势,是飞行器发展的重要方向之一。在分析一类可变飞行模态飞行器运动机理的基础上,建立了能够反映该类飞行器共有特性的、抽象的统一数学模型结构。并在统一模型的框架下,建立了鸭式旋翼/机翼无人机的六自由度数学模型,并对其进行仿真验证。仿真结果表明,该建模方法可以实现该类飞行器各转换模态的配平,并具有较强的通用性。

The Study of Unified Modeling about a Type of Aircrafts with Variable Flight Modes

The aircraft with variable flight modes, which had the abilities of VTOL, hovering, and high speed cruise, was an important direction of the future aircraft development. A unified model structure was built based on the analyzing the principle of variable flight modes. The common character of this aircraft was showed by the unified model structure which was abstract. Based on this unified model, the six free degree model of the canard rotor/wing UAV was built. Results from a simulation are presented the airc...
