摘要
提出了一种车轮-螺旋桨混合驱动的飞行汽车起飞滑跑策略:使用车轮驱动起步、加速至切换速度,随即将动力切换至螺旋桨,采用螺旋桨驱动完成后续滑跑及爬升。分别建立了车轮-螺旋桨混合驱动和常规螺旋桨驱动两种滑跑策略的数学模型,运用发动机台架试验数据修正仿真模型,通过实例计算验证两种滑跑策略下的滑跑距离。仿真结果表明,采用的车轮-螺旋桨混合驱动滑跑策略能够有效缩短飞行汽车滑跑距离。
In this paper,a new take-off taxiing strategy was proposed for flying car driven by wheel-propeller:wheel drive was used to accelerate the flying car to the switch speed during the take-off process,then power was switched to propeller from wheels to complete the subsequent taxiing and climbing process in the following stage.Two mathematics models were established respectively for the wheel-propeller hybrid driving strategy and the strategy which used only propeller to drive.The models were amended by the experimental data of flying car engine bench testing.With real case,the taxiing distances of the two strategies were calculated and verified.The results show that taxiing distance of flying car is effectively shortened by using the wheel-propeller hybrid driving strategy.
