摘要
文章利用某型直升机双侧外挂构型和无外挂构型的平飞性能飞行试验数据,从工程应用方面研究了直升机双侧外挂两枚鱼雷构型对平飞性能的影响,主要研究了双侧外挂构型对直升机的需用功率、经济速度、最大平飞速度、航程、续航时间、直升机的俯仰角等参数的影响。直升机双侧外挂时,会造成直升机气动外型改变,型阻和废阻增大,俯仰角减小、最大平飞速度减小、航程减小,但最大续航时间保持不变。
In this paper,based on the flight test data of the parallel flight performance of a helicopter with and without plug-in configuration,the influence of two torpedo configurations on the flat flight performance of a helicopter is studied from the aspect of engineering application.This paper mainly studies the effects of bilateral plug-in configuration on helicopter parameters such as required power,economic speed,maximum flat flight speed,flight range,flight duration,pitch angle and so on.When the helicopter is hung on both sides,the aerodynamic shape of the helicopter will change,the shape resistance and waste resistance will increase,the pitch angle,the maximum flat flight speed and the flight range will decrease,but the maximum flight duration will remain unchanged.
