Dandelion-imitated Mars aircraft and device and control method thereof

Abstract

The invention discloses a dandelion-imitating Mars aircraft applied to Mars and a device and a control method thereof, and belongs to the field of aircrafts. The aircraft is similar to a dandelion in appearance and comprises an equipment cabin, a load cabin and a plurality of flexible crown hairs. A plurality of crown hairs are uniformly fixed on the outer wall of the equipment cabin in the circumferential direction, and all the crown hairs jointly form a crown hair group; each crown hair comprises a fixed end used for being connected with an equipment cabin and a free end capable of being bent upwards, and the movement direction of the aircraft is adjusted by controlling the bending degree of each crown hair; in an initial state, all the crown hairs are positioned on the same horizontal plane; and a load cabin is hung at the bottom of the equipment cabin. The crown hair adopts a novel bicrystal form driving structure, and the thermal expansion difference of a material is controlled through voltage, so that the crown hair is bent to different degrees. The aircraft has the advantages of being good in lift force characteristic, long in air control time, controllable in posture and convenient to carry, and can be applied to future Mars exploration engineering in China.

Description

technical field [0001] The invention belongs to the field of aircraft, in particular to a dandelion-like Mars aircraft applied to Mars, a device and a control method thereof. Background technique [0002] Among the planets that have been detected so far, Mars is considered to be the most suitable planet for human immigration. Mars is the closest planet to Earth except Venus, and the environment of Mars is most similar to that of Earth. Scientists have discovered that there is a large amount of ice at the poles of Mars, and there was once a large amount of liquid water on Mars. In recent years, various countries have proposed plans for Mars exploration and immigration. On July 23, 2020, my country successfully sent the "Tianwen-1" probe into the predetermined orbit, starting the journey of Mars exploration, and taking the first step in China's independent planetary exploration. The Tianwen-1 probe consists of an orbiter, a lander and a rover. At present, the Mars rovers o...

Problems solved by technology

The direct use of traditional earth fixed-wing or rotary-wing aircraft on Mars will lead to poor lift characteristics, a greatly reduced lift-to-drag ratio of the airfoil, and poor performance of the aircraft. It can be seen that the application of ordinary earth aircraft on Mars There are great challenges, and it is extremely urgent to design an aircraft suitable for the low Reynolds number environment of Mars
