可变直径旋翼直升机飞行性能及操纵策略
Flight Performance and Manipulation Strategy of Variable Diameter Rotor Helicopter
摘要
Abstract
As an important part of the rotor morphing technology,the variable diameter rotor can effectively meet the re-quirement for the rotor to adaptively work in a high-performance state.In order to obtain the impact of variable diameter rotors on the helicopter flight performance,firstly,a typical helicopter flight dynamic model is established,and the impact of variable diameter on the helicopter vertical and horizontal flight performance is studied.The results show that increas-ing the rotor diameter can effectively improve the vertical climb rate,practical hovering ceiling and hovering efficiency,while decreasing the rotor diameter can increase the flight time,range and maximum forward flight speed.Then,a set of required power calculation methods is given,and the change rules of required power of variable-diameter-rotor helicop-ters are analyzed in different flight states.Finally,a variable-diameter rotor manipulation strategy is proposed based on the minimum consumption of required power and lower control complexity.关键词
