摘要
复合式直升机既可垂直起降、悬停和低速飞行,又具有高速、远航程和长航时的性能特点,无论是在军事还是在民用领域都具有非常重要的实用价值。对比常规直升机,总结了复合式直升机的性能优势,介绍了现今已发展的复合式直升机型号。针对复合式直升机的总体构型、气动干扰、操纵策略及操稳特性进行了较细致的总结。对复合式旋翼桨叶结构的选择、辅助推力/升力系统的抉择、复合式布局的技术特点进行了总结和分析。
The compound helicopter can vertically take-off,hover and conduct low speed flights.At the same time,it has high speed,long range and endurance.These features make it significant in both military and civilian fields.This paper concludes the advantages of compound helicopter compared with the traditional configuration,and gives an overview on the developing compound products nowadays.The overall configuration and aerodynamics interference are analyzed in detail,along with the control strategy and control/stability characteristic concluded.What's more this work analyzes the multiple choices of rotor blade configuration and the assistant trust/lift system,and summarizes the technology features of the compound helicopter.
