摘要
面向直升机电动化技术发展需求,综合考虑直升机尾旋翼系统设计中的总体、气动、结构、动力学、新型能源动力系统等要求,从尾桨飞行性能、使用安全性、维修保障性等方面建立了能够全面综合评估尾桨构型方案的评估方法,用以指导未来电动化直升机的尾旋翼系统设计。本文以国产某轻型直升机尾旋翼系统为设计基准,在满足抗侧风能力与原准样机相当的基础上,针对单涵道变转速、双涵道变转速、三涵道变转速三种电驱动反扭矩系统构型方案,从操纵功效、系统重量、安全性、可靠性等方面综合对比评估了各构型方案的优劣,研究结果表明,三涵道变转速方案相较于其他两种方案综合性能最优,可优先发展并应用于未来轻型直升机电驱动尾旋翼系统。
Facing the development requirements of helicopter electrification technology,and comprehensively considering the demands of overall design,aerodynamics,structure,dynamics and new energy dynamical system of helicopter tail rotor system design,an evaluation method that can comprehensively evaluate the tail rotor configurations is established from the aspects of tail rotor’s flight performance,safe operation and maintenance support performance,which can be used to guide the design of tail rotor system of future electric helicopters.Based on the tail rotor system of a domestic light helicopter,and on the basis of meeting the requirements of the cross wind resistance equivalent to the original prototype,this paper puts forward three different types of configurations of electric drive anti-torque system,including single duct variable speed,double ducts variable speed and three-duct variable speed.The advantages and disadvantages of each configuration are comprehensively compared and analyzed from the aspects of operating efficiency,system weight,safety and reliability.The results show that three-duct variable speed configuration has the best comprehensive performance and can be preferentially developed and applied to the electric tail rotor system of future light helicopters.
