新构型高速旋翼飞行器的现状和发展趋势

Status and development trends of new configuration high-speed rotorcraft

高速化、远程化是当前旋翼飞行器的重要发展方向,常规构型直升机已难于满足用户越来越高的使用需求,发展新构型已经成为重要的解决途径与突破方向。梳理了国外新构型高速旋翼飞行器的发展历程,按复合式、倾转式和停转式的分类对新构型进行了归纳整理,重点阐述了近期发展势头迅猛的几种构型的主要特点与发展情况。在此基础上,对高速构型旋翼飞行器的现状进行了总结,并对其未来的发展趋势进行了预测分析。

It has been an important development trend to design VTOL rotorcraft with high speed and long endurance. Designing new configurations has been a significant choice for the mission objectives, since it is too hard for conventional helicopters to meet the customer’s requirements. This paper classified the new configuration high-speed rotorcraft into three categories: compound helicopter, tilt aircraft and stoppable rotor aircraft, and provided an overview of the high-speed rotorcraft abroad based on the classification, focusing on the main characteristics and development of the most popular rotorcraft recently. The development situation and the future of high-speed concepts were then concluded and analyzed.
