摘要
对直升机尾桨机械性失效类型进行了总结,分析对比了在不同失效状态下直升机的响应特点,并对保证飞行安全所应采取的措施进行了讨论。提出了一种用于检验直升机尾桨机械性失效时恢复配平能力及着陆能力的试飞方法,并通过工程试飞进行了验证。
The different responses of the example helicopter in the failure of tail-rotor induced by various mechanical malfunctions were compared in this paper. Based on the flight dynamics analysis, some flight technique to ensure the craft avoiding the ruinous sequent caused by tail-rotor failure was discussed. A series of ways were drawn out to test the capability of flight and landing under the condition of tail-rotor failure and used in a helicopter testflight. The test result indicates this method is efficacious.
