Embodiment 1
[0015] The present embodiment is an unmanned aircraft powered by solar energy, which adopts a single wing with a large aspect ratio and a V-shaped tail layout. The straight section of the wing is a rectangular wing with a span length of 300cm and a chord length of 30cm; the outer winglet is a right-angled trapezoidal wing with an upturn of 30°, a chord length of 30cm, a sweep of 15°, and a tip ratio of 0.67; the fuselage length is 186cm.
[0016] This embodiment includes wing 4 , outer winglet 5 , V-shaped tail 8 , thin-film solar cell 6 , fuselage 7 and equipment cabin 2 . Forty pieces of flexible thin-film solar cells with a length of 25 cm and a width of 7 cm are pasted on the upper surface of the skin of the straight section of the wing. The main structure of the wing 4 and the V-shaped tail 8 is balsa wood and aviation laminates, and the skin is a heat-shrinkable film. Fuselage 7 is made of carbon fiber composite material pipe. Equipment compartment 2 is made of balsa w...
