| 摘 要： | 研究了无铰直升机在风切变场中的稳定性和操纵性.采用挥舞-变距-扭转耦合的旋翼动力学模型、广义涡流理论所导出的诱速分布模型、以及风切变的线性模型,来建立直升机在风切变场中的分析模型.通过对直升机动稳定性特征根和风切变场中的操纵响应的计算,对风切变场中直升机的响应做了初步分析.

| Abstract: | In this paper,the stability and control of a hingeless helicopter in wind shear were investigated.The flap-pitch(including the elastic deformation of the control system)-torsion coupling rotor dynamic model,the model of nonuniform induced velocity distribution derived from the generalized vortex theory,and the linear wind shear model,were used for calculating and analyzing the stability and control of a helicopter.The stability roots and the control response of the helicopter were first calculated.Then the response of the helicopter in wind shear field was analyzed according to calculated results. |
