改善装机条件下太阳能无人机的气动性能
The influence of improved installed propeller on the solar UAV aerodynamic performance
摘要
Abstract
The performance of the solar UAV propeller under the improved installed condition is studied.Firstly,wind tunnel test is carried out to verify the accuracy of the numerical simulation method choosed in this paper in the case of the installation of a separate propeller.Secondly,the effects of the propeller installation position,the individual propeller and the winged propeller on the performance of the propeller were calculated by using the constant and unsteady numerical simulation methods,and the influence of the improved propeller on the performance of the UAV was calculated.The results show that the winged propeller causes the propeller thrust and power to increase,and the propeller slipstream has little effect on the nacelle,mainly due to the acceleration of the slipstream leading to a slight increase in drag.Propeller slipstream results in lower UAV wing lift curve slope,higher drag and higher pitch stability.As the distance between the propeller and the leading edge of the wing increases,the performance of the winged propeller gradually approaches that of the propeller without the wing.关键词
