摘　　要：螺旋桨和发动机的匹配工作性能直接关系到螺旋桨飞机的总体性能。针对活塞动力螺旋桨飞机,研究了巡航阶段桨发匹配选速方法。以螺旋桨、活塞发动机和飞机飞行性能计算模型为基础,通过引入匹配推力系数参数,建立了螺旋桨进距比与螺旋桨效率之间的关系,并采用螺旋桨效率和发动机耗油率的比值寻优的方法,获得最优桨发匹配转速。以此寻优方法,针对飞行过程中飞机不断降低的重量,计算不同的最优桨发匹配转速,作为巡航剖面桨发匹配选速依据,并进行了性能计算分析。计算结果表明,飞机巡航阶段采用桨发匹配最优选速飞行,相比于恒转速飞行,可以显著地提升巡航性能。Prop-Engine cooperation performance is directly related to the overall performance of the propeller aircraft.A speed selection method for propeller engine matching during cruise phase was studied for piston powered propeller aircraft.Based on the calculation models of propellers,piston engines,and aircraft flight performance,the relationship between propeller pitch ratio and propeller efficiency was established by introducing matching thrust coefficient parameters.The optimal propeller engine matching speed was obtained by using the ratio of propeller efficiency to engine fuel consumption.Using this optimization method,different optimal propeller engine matching speeds were calculated for the aircraft’s continuously decreasing weight during flight,as the basis for selecting cruise profile propeller engine matching speeds,and performance calculation analysis was conducted.The calculation results show that the optimal speed selection flight using propeller engine matching during the aircraft cruise phase can significantly improve cruise performance compared to constant speed flight.
