| 摘 要： | 在直升机的仿真建模中,涡轮轴发动机模型的准确程度直接影响着动力系统模型的逼真程度,同时它也是直升机动力学建模的重要组成部分。为解决上述问题,研究了涡轮轴发动机建模方法,给出了考虑旋翼负载反馈的发动机控制系统模型,以及内、外环串联控制回路的发动机输出功率控制方式,设计了涡轮轴发动机动力调节的控制律,从而实现了涡轮轴发动机和旋翼一体化的直升机动力系统仿真模型,并通过仿真实例对模型进行验证,证实了模型的正确性。

| Abstract: | Modeling of power system plays an important role in the modeling of helicopter dynamics system. The accuracy of turbo-shaft engine model affects the fidelity of power system model. Modeling techniques of turbo-shaft engine were studied first. The modeling of engine control based on rotor load feedback was developed. An inner-outer series-wound control loop for adjusting engine output power based on the feedback control was developed,and the control laws were designed. The modeling of helicopter power system... |
