Abstract

The invention relates to the technical field of aerostat accessory equipment, and discloses a foam-sandwich carbon fiber flywheel and a manufacturing method thereof. The foam-sandwich carbon fiber flywheel comprises a flywheel inner ring, a flywheel middle ring and a flywheel outer ring which are coaxially arranged at intervals from inside to outside in sequence, and further comprises a pluralityof spokes which are arranged between the flywheel inner ring and the flywheel outer ring in the radial direction of the flywheel outer ring; the spokes are evenly distributed in the circumferential direction of the flywheel outer ring; the flywheel inner ring is of a carbon fiber composite material solid structure; and the flywheel middle ring, the flywheel outer ring and the spokes are of a carbon fiber composite material hollow structure, and the inside of the carbon fiber composite material hollow structure is filled with foam core materials. The flywheel further comprises a plurality of balancing weights connected with the flywheel outer ring, and the balancing weights are evenly distributed in the circumferential direction of the flywheel outer ring. The foam-sandwich carbon fiber flywheel has excellent mechanical property and realizes the design requirement that the weight of a flywheel body structure is reduced to the greatest extent; and the design of filling of foam core effectively improves the torsional rigidity of the flywheel in the process of rotation.

Description

technical field [0001] The invention relates to the technical field of high-altitude balloon accessory equipment, in particular to a foam sandwich carbon fiber flywheel and a manufacturing method thereof. Background technique [0002] High-altitude balloons, also known as high-altitude scientific balloons, refer to unpowered aerostats that fly in the stratosphere. Due to their low cost, convenient organization of flight, and short test periods, high-altitude balloons are increasingly favored by scientists. Usually, when the high-altitude balloon is working normally, its azimuth and attitude need to be controlled to ensure that the equipment mounted on it can work stably. Usually, a reaction flywheel system is required, and the speed of the flywheel is adjusted by the motor, and the reaction torque generated by the change of the flywheel angular momentum is used. High altitude balloon azimuth stabilization and adjustment. [0003] At present, the large-volume high-altitude s...
