Abstract

The invention provides a variable density unmanned airship based on solar energy. The variable density unmanned airship comprises an airship body (1), lifting airfoils (4), an empennage (6) and solarcell panels (3), wherein the airship body (1) is in a drop-shaped symmetrical streamline shape, the cross empennage (6) is arranged at one end of the tip of the airship body (1), the lifting airfoils(4) are symmetrically arranged at the two sides of the airship body (1), the solar cell panels (3) are laid on one side, facing the sun, of the two lifting airfoils (4) and the airship body (1), a power device (9) for controlling the airship body (1) to float or sink is arranged inside the airship body (1), and pipelines which extend to the two ends of the airship body (1) and supply air inlet andexhaust to the airship body are connected to the two sides of the power device (9) respectively. By means of the variable density unmanned airship, extra energy sources are not needed, and the airship can be on guard in the air for a long time. Through the density change of inflation and deflation of a compressor itself, floating and sinking are achieved; the airship is powered by the solar energy, and the pollution is not caused.

Description

technical field [0001] The invention belongs to the field of unmanned airships, in particular to a variable-density unmanned airship based on solar energy. Background technique [0002] Airships generally use internal combustion engines or batteries as power, and their cruising time is limited. Recently, solar-powered airships have appeared, but during the entire flight process, the motor needs to be turned on to move forward and control the flight direction, which consumes a lot of energy. The demand for solar arrays and battery capacity is high, which makes the airship itself bulky. Contents of the invention [0003] The object of the present invention is to provide a variable-density unmanned airship based on solar energy, which overcomes or alleviates at least one of the above-mentioned defects in the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: a variable-density unmanned airship based on solar energy...
