Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] The multi-directional attitude control device of the present invention is used for the attitude adjustment of the airship in the adjacent space. It is composed of a plurality of one-way distance variable attitude adjustment mechanisms 1 and multi-directional attitude control brackets 2, all of which are installed on the head of the airship 3 in the adjacent space, such as figure 1 shown.

[0030] The one-way variable pitch and attitude adjustment mechanism 1 includes a propeller module 101, a motor module 102, and a pitch variable module 103, as figure 2 shown.

[0031] The propeller module 101 includes a fixed propeller hub 101a, a movable propeller hub 101b, a connecting shaft 101c and a propeller blade 101d, such as image 3 shown. Wherein, the propeller fixed propeller hub 101a is a cube structure, and there are connecting shafts 101c at the ce...

Abstract

The invention discloses a multi-directional attitude control device, which belongs to the technical field of unmanned airships, and includes a plurality of unidirectional pitch-variable attitude adjustment mechanisms 1. The mechanism is driven by a drive motor to drive a connecting rod structure installed on the propeller hub to realize the thrust of the propeller. Simultaneous manipulation of direction and size. The above-mentioned multiple one-way variable-distance attitude-adjusting mechanisms are installed through multi-directional attitude control brackets, and then two or more one-way variable-distance attitude-adjusting mechanisms are arranged vertically or at any angle to realize the control decoupling of the airship in different directions. The invention has the characteristics of simple structure, strong controllability and wide applicability, and can adapt to the low-temperature and low-pressure flying environment in the stratosphere where the airship is located.

Description

technical field [0001] The invention belongs to the field of aerostats and relates to a multidirectional attitude control device. Background technique [0002] During the flight of an airship in near space, controlling the attitude of the airship to make it fly or maneuver according to the predetermined track is a very critical link. The use of the attitude adjustment device is of great significance for the airship to achieve tasks such as wind-resistant flight and regional residence. The existing attitude adjustment devices are mainly single-direction control or complex vector control, which have low control efficiency and heavy structural weight, so they have little engineering application value. [0003] In view of the many disadvantages of existing attitude adjustment devices, a simple and efficient multi-directional attitude control device for airships in near space is particularly important. Contents of the invention [0004] The purpose of the present invention is...
