In order to ensure the stable work of fighter planes while increasing their maneuverability , it is necessary to investigate the vibration performance of aero - engine in maneuver flight 为了确保飞机在提高其机动性能的同时还能稳定工作,不发生故障,有必要对机动飞行条件下的发动机转子系统的振动特性进行研究。
Nowadays , squeeze film dampers ( sfd ) are used to reduce the vibration in many aero - engines , and then their performance in maneuver flight will affect the whole engine 现今,有不少航空发动机都采用了挤压油膜阻尼器来减小发动机的振动,而挤压油膜阻尼器在机动过载的作用下的运动特性将对发动机转子产生重要影响。
Abstract : this paper presents an inverse simulation algorithm of determining the pilot control law as well as the time histories of helicopter velocity , angular velocity and flight altitudes to follow a given helicopter maneuver flight path 文摘:本文给出了一种直升机机动飞行的逆模拟方法以计算跟随预定飞行轨迹的驾驶员操纵。
It is concluded that the influences of maneuver flight on the rotor system of an aero - engine are evident , therefore , they should be taken into account during design of the engine 研究结果表明,机动飞行所产生的附加离心力和附加陀螺力矩对发动机转子振动的影响是明显的。因此,在设计战斗机的发动机转子系统时,必须考虑机动飞行的影响。
