高速直升机通过构型的革新,可以在保留直升机使用特点的基础上提高飞行速度,是直升机未来的重要发展方向之一。本文对国外相继出现的各种构型的高速旋翼飞行器进行了简要回顾,介绍了采用前行桨叶概念旋翼构型的高速直升机,对前行桨叶概念旋翼的气动、动力学和操纵特性做了分析研究,并梳理了相关的在研关键技术。
Through the innovation of configuration, high-speed helicopters can improve flight speed while retaining the characteristics of helicopters and become one of the important development directions for helicopters in the future. In this paper, we briefly reviewed the high-speed rotorcraft of various configurations abroad, and introduced the high-speed helicopter with the rotor blade concept of forward blade. The aerodynamic, dynamic and maneuvering characteristics of the forward blade concept rotor Analysis and research, and sort out the relevant key technology in the study.
