共轴刚性旋翼构型高速直升机发展研究

The Development Overview of Coaxial Rigid Rotor Helicopter

共轴刚性旋翼带推力桨构型在保留常规直升机优异近地面机动能力的基础上,可实现速度与航程提升一倍,是下一代军用直升机的主要构型。本文从直升机构型发展需求出发,系统梳理了共轴刚性旋翼的概念原理、技术攻关和型号预发展过程,并以美军未来高速直升机型号发展和直升机技术发展趋势,提炼并概括了以高速直升机装备为代表的下一代军用直升机的典型技术特征,对高速直升机的发展提出一些建议。

Helicopter with coaxial rigid rotor can double the speed and range on the basis of retaining the excellent near-ground maneuverability of conventional helicopter.It is the main configuration of the next-generation military helicopter.Based on the development requirements of helicopter configuration,this paper systematically combs the concept principle of coaxial rigid rotor,technical research and model pre-development process.According to the future development of high-speed helicopter models and the development trend of helicopter technology,it refines and summarizes the typical technology of the next generation military helicopter represented by high-speed helicopter equipment.Through induction and summary,this paper introduces the corresponding enlightenment and puts forward some suggestions on the development of high-speed helicopters.
