Tandem-wing solar unmanned plane pneumatic configuration structure

The invention provides a tandem-wing solar unmanned plane pneumatic configuration structure which comprises a main wing, a back wing, a small wing, two fins and two side plates, wherein the main wing, the back wing and the small wing have shapes of high aspect ratio wings; the two fins are respectively connected to the rear ends of the two side plates through a connection plate; the fins, the connection plate and the side plates are in the same plane; the main wing, the back wing and the small wing are horizontally arranged, and the two ends of the main wing, the back wing and the small wing are respectively and fixedly arranged onto the two side plates; the back wing is placed at the rear of the main wing; the small wing is placed under the main wing and the back wing. The tandem-wing solar unmanned plane pneumatic configuration structure provided by the invention has a structure with high lift-drag ratio, large load capacity and high-strength wings, and can meet all-direction detection and warning in front and back/left and right directions.
