Description

technical field [0001] The invention relates to the field of testing the hovering characteristics of an unmanned aerial vehicle rotor system. Background technique [0002] With the continuous development of deep space exploration technology, the exploration of extraterrestrial planets has gradually become a new direction of scientific researchers' attention, and it is of great significance for human beings to explore extraterrestrial life and explore the origin of life. Mars is adjacent to the Earth in the solar system and has a similar size and diurnal change to that of the Earth. In addition, Mars was found to have a thin atmosphere and is considered to be one of the exoplanets that humans can live in in the future. In order to further accelerate the exploration of Mars, a concept of an aircraft for Mars exploration has been proposed and continuously promoted. Its main forms include: fixed wing, floating air balloon, flapping wing and rotary wing. Among them, it is diffic...
