摘要: 根据经典的垂直飞行涡流理论及共轴式直升机半差动航向操纵的结构特征,推导了共轴双旋翼直升机垂直飞行的航向动力学方程.运用有关共轴双旋翼在悬停及垂直飞行状态时气动特性的理论和实验数据,得出了共轴双旋翼直升机垂直飞行航向动力学方程的解析式.分析结果与该型直升机飞行特性一致.

Abstract: The dynamic equation of a semi-differential co-axial helicopter in vertical flight was set up and solved based on classical vortex theory and character of aerodynamic interference between upper and lower rotors of the co-axial helicopter. There exists a coupling relationship between vertical movement and direction rotation with direction control in vertical flight of the helicopter. Calculation example results indicate that the equations of dynamic response proposed for vertical movement and direction rotation reflect flight character of this helicopter.
