| 摘 要： | 论述了一种通用的直升机飞行动力学全量数值仿真模型及其实现，该模型有６个机体自由度和３个旋翼自由度。以旋翼系统的仿真为重点，将直升机旋翼的气动力和力矩通过沿半径和方位角的解析积方求得，并计入了旋翼挥舞动力学的影响。仿真模型以某型直升机为算例，并加入了增稳系统，对仿真模型飞行特性进行了初步的验证，结果表明，所述模型思路是正确的。

| Abstract: | This paper study a nonlinear, total force helicopter simulation model.The simulation model is suitable for conventional helicopter with a single main rotor.It has nine degrees of freedom six rigid body and three rotor flapping.The rotor model assumes rigid blades with rotor forces and moments radially integrated and summed about the azimuth, and it accounts for the dynamic effect of blade flapping.This simulation model is full complemented in C program language,all equations and caculation are in time domain. |
