Abstract

The invention discloses a flight control method and apparatus for a multiaxial flight vehicle. The method includes: detecting whether a plurality of power systems with countershaft design are abnormal by a flight control system; and when the flight control system detects that any power system is abnormal, adjusting the countershaft power system to make the multiaxial flight vehicle land stably. The method and the apparatus provided by the invention solve the problem that the multiaxial flight vehicle cannot maintain balance when any power system in the multiaxial flight vehicle is abnormal in the prior art, and the multiaxial flight vehicle still can land stably when abnormality occurs to any power system of the multiaxial flight vehicle.

Description

Technical field [0001] The invention relates to the field of aircraft flight control, in particular to a method and device for flight control of a multi-axis aircraft. Background technique [0002] At present, multi-axis aircraft are widely used in civil, commercial and military fields. In the civilian field, more and more extreme sports enthusiasts use multi-axis aircraft for video recording. In the commercial field, in addition to carrying video equipment for various sports events In addition to tracking aerial photography, it has entered the logistics industry and can send goods to remote areas where human distribution is difficult and slow. Therefore, multi-axis aircraft has a wide range of applications and broad market prospects. [0003] The existing multi-axis aircraft uses a multi-axis power system to provide power and maintain balance. Therefore, after any power system is abnormal, the multi-axis power system will lose balance and crash, causing damage to the aircraft and ...
