| 摘 要： | 建立了适用于直升机机动飞行仿真的动力学模型。为了提高模型的真实度,着重通过瞬态操纵实验研究建立了旋翼非定常气动模型;又通过旋翼/ 机身气动干扰试验研究,并运用神经网络技术建立了一种新的机身气动力模型。使用该仿真模型做出的UH260A 直升机仿真计算结果与飞行试验数据符合良好。

| Abstract: | An aerodynamic model suitable for simulating the helicopter maneuver flight is p resented. In order to enhance the credibility of the model, based on the experim ent of the rotor response characteristics to rapid control input, a noolinear ae rodynamic model of the rotor was built up. The experimental investigation of the aerodynamic interaction effect of the rotor wake on the helicopter fuselage was executed also, and the aerodynamic model of fuselage was built up with multipla yer feed forward neural networks. The simulation model based on the experimenta l investigation is credible and usable for research of helicopter maneuver fligh t. It is verified by some flight test data of UH 60A helicopter. |
