摘要
对某型无人直升机悬停状态飞行动力学模型进行了结构框图分解,分析了从操纵输入到状态响应的原理机制,应用美军标ADS-33飞行品质规范评估了该型无人直升机在悬停状态的稳定性、中小幅值姿态变化响应和轴间耦合特性等品质等级,指导了飞行控制律的设计,使闭环后整机飞行品质达到了等级1的要求。
An unmanned helicopter dynamic model in hover was studied in this paper, the internal mechanism of control input to states response was indicated following the model block diagram de- composition, the qualities of stability, small and moderate amplitude attitude changes and interaxis coupling were assessed in accordance with requirements of ADS - 33E - PRF. Flight control design was guided according to the analysis results, bring on handling qualities of Level 1.
