摘要
针对通勤类飞机总体设计参数和飞行任务剖面需求,根据氢电-锂电推进系统架构方案,提出了推进系统参数匹配方法和能源动态平衡管理策略。以19座级通勤飞机作为验证对象,对其动力装置和储备能源进行了选型和管理研究。根据选型的分布式推进气动布局方案,进一步采用全析因试验设计方法分析了螺旋桨转向对飞机气动特性的影响,获得了有利于飞机巡航状态的螺旋桨转向配置方案。
Aiming at the overall design parameters and mission profile requirements of commuter aircrafts,according to the hydrogen-lithium propulsion system architecture scheme,the propulsion system parameter matching method and energy dynamic balance management strategy were proposed.A 19-seat commuter aircraft was used to select and manage the power plant and reserve energy.According to the selected distributed aerodynamic layout scheme,then the effects of propeller rotation directions on aircraft aerodynamic characteristics were analyzed with full factorial design of experiments,and the optimum propeller rotation direction configuration for aircraft cruise states was obtained.
