摘　　要：为设计在满足悬停、前飞工况要求的前提下均具有较高的巡航效率和更长的航时的无人机(UAV)倾转涵道螺旋桨,提出了一种倾转涵道螺旋桨的设计及优化方法。该方法基于叶素动量理论、涵道螺旋桨的涡流理论对桨叶进行快速设计,通过计算流体动力学(CFD)修正与迭代两次即可得到满足设计要求的桨叶,并通过综合悬停、前飞两点优化设计得到最终的倾转涵道螺旋桨。设计结果表明:在满足悬停、前飞两个工况的设计要求的前提下,螺旋桨的巡航效率提升至92.3%,航时增加7.1%。该方法设计精度高且能够分别以悬停、前飞为最优设计点进行设计,并对两点综合考虑,使其效率、航时更大化。该方法设计的倾转涵道螺旋桨能够满足巡航效率与航时要求。In order to design the tilting ducted propeller of unmanned aerial vehicle(UAV)with higher cruising efficiency and longer flight time on the premise of meeting the requirements of hovering and forward flight,a design and optimization method of tilting ducted propeller was proposed.According to this method,the blade was designed firstly by the classical method using the blade element momentum theory and the vortex theory of the ducted propeller.The blade meeting the design requirements can be obtained through computational fluid dynamics(CFD)correction and the classical method was iterated,and the final tilting ducted propeller was obtained through the iterative and comprehensive optimization design in hover and forward flight states.The design results showed that under the premise of meeting the design requirements of hovering and forward flight,the cruising efficiency of the UAV was increased to 92.3%,and the flight endurance was increased by 7.1%.This method can achieve high design accuracy and can be designed with hover and forward flight as the optimal design points,and the two optimal design points were considered comprehensively to increase the UAV’s cruising efficiency and flight time.The tilting ducted propeller designed by this method can meet the requirements on the UAV’s cruising efficiency and flight endurance.
