Miniature shaftless ducted rotor aircraft and flight control method thereof

Abstract

The invention provides a miniature shaftless ducted rotor aircraft and a flight control method thereof. The miniature shaftless ducted rotor aircraft comprises a duct as well as a plurality of paddlewing structures and self-adaptive control surface structures which are mounted in the duct; each paddle wing structure comprises an upper fixed bearing and a lower fixed bearing which are fixed on theinner wall of the duct, a motor, a stator, a rotor, paddles and a rotating ring are arranged between the upper fixed bearing and the lower fixed bearing, an air gap is formed between the stator and the rotor, and the paddles are connected with the rotating ring so as to be connected with the stator into a whole; and the self-adaptive control surface structure is distributed below the paddle wingstructure. Compared with a traditional ducted rotor wing, the miniature shaftless ducted rotor aircraft generates larger lift force; the motor-duct-rotor integrated design enables no gap to exist between the blades and the motor, the influence of small deformation of the duct body on the overall aerodynamic efficiency and safety is reduced, and meanwhile, the control mechanism is simple, light inweight, easy to control and more suitable for micro aircrafts.

Description

technical field [0001] The invention relates to the field of rotorcraft, in particular to a miniature shaftless ducted rotorcraft and a flight control method thereof. Background technique [0002] Micro air vehicle has attracted much attention because of its special purpose. An important application is military reconnaissance, which can be equipped to soldier squads for enemy reconnaissance and surveillance. It can also be used for war risk estimation, target search, communication relay, monitoring of chemical, nuclear or biological weapons, and reconnaissance of the interior of buildings. It can be applied to various war environments such as cities and jungles. Because of its portability, simple operation, and good safety, it can be equipped in large quantities in the army. In the non-military field, MAVs equipped with corresponding sensors can be used to search for disaster survivors, sources of toxic gases or chemicals, and eliminate crop pests. [0003] There are thr...

Problems solved by technology

However, at present, micro-rotor aircraft generally have the disadvantages of complex control mechanisms, which lead to larger aircraft volume and low operating efficiency of the control mechanisms.
