摘要
自从20世纪70年代美国西科斯基公司在黑鹰上成功采用倾斜尾桨构型方案后,30多年来,先后又有CH53E、S92、AB139等多种大、中型运输直升机采用倾斜尾桨构型,本文主要分析尾桨倾斜对直升机飞行性能的影响,并以某样例直升机为例进行了两种尾桨构型方案飞行性能的对比计算,同时也对倾斜尾桨和常规尾桨设计方案的优缺点进行了讨论。
In the last 70's,american sikorsky aircraft corporation successful adopted mast tilted tail rotor configuration in the black hawk helicopter,which has been used in kinds of large and medium transport like CH53E,S92 and AB139 during the past 30 years.this paper mainly analyzes the effect of mast tilting to helicopter's flight performance.Take one helicopter for example,flight performance of both tail rotor configuration is calculated for compare,besides the advantages and disadvantages of the mast tilting and the common tail rotor configuration designs are discussed.
