Abstract

Successful test flights of solar powered unmanned aerial vehicles (UAVsat home and abroad are using conventional wing layout.The overall parameters of a kind of solar energy UAV were determined, it is propeller powered and the wing adopts unconventional tandem wing configuration.Based on FLUENT software and calculation of 3D viscous flow field, verification calculation shows the tandem wing is better than single wing in aerodynamic performance.Two-dimensional numerical simulation of low speed aerodynamic characteristic of the tandem wing was performed in sixty kinds of different relative horizontal distance and height for 0° and 6º attack angle.Through analysis on the results of lift, drag and lift-to-drag ratio, it is found that aerodynamic performance of the tandem wing is relatively best when the relative horizontal distance is 5 times the chord and relative vertical height is 0.4 times chord.Furthermore, configuration parameters of the tandem wing, aileron and rudder were determined, making 1:2 scaled model of the tandem wing UAV and testing flight.

Key words： solar energy unmanned aerial vehicle; tandem wing configuration; general parameters; low speed aerodynamic performance; numerical simulation; scaling flight test model
