The invention relates to the technical field of high-altitude balloon accessory equipment and discloses a lightweight flywheel and a manufacturing method thereof. The lightweight flywheel comprises aflywheel inner ring, a flywheel middle ring and a flywheel outer ring which are sequentially and coaxially arranged at intervals from inside to outside, and further comprises a plurality of spokes arranged between the flywheel inner ring and the flywheel outer ring, wherein the spokes are evenly distributed in the circumferential direction of the flywheel outer ring. The spokes comprise first spokes and second spokes which are arranged in the radial direction of the flywheel outer ring, the flywheel inner ring is connected to the flywheel middle ring through the first spokes, and the flywheelmiddle ring is connected to the flywheel outer ring through the second spokes. The flywheel inner ring, the flywheel middle ring, the flywheel outer ring and the spokes are all made of carbon fiber composite materials. The lightweight flywheel further comprises a plurality of balancing weights connected to the flywheel outer ring, and the balancing weights are evenly distributed in the circumferential direction of the flywheel outer ring. According to the lightweight flywheel, the outer ring concentrated mass design is adopted, the mass of the carbon fiber flywheel body can be minimized, and then maximization of the rotational inertia of the flywheel is achieved.
Description
technical field [0001] The invention relates to the technical field of high-altitude balloon accessories, in particular to a lightweight 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 and flight, and short test periods, high-altitude balloons are increasingly favored by scientists and widely used. It is used in the research of high-energy astrophysics, cosmic rays, infrared astronomy, atmospheric physics, atmospheric chemistry, ground remote sensing, high-altitude physics, physiology, microgravity experiments, etc., and is also widely used in the pre-research and test flight of outer space space equipment and military aspect etc. When the high-altitude balloon is working normally, it needs to control its azimuth and attitude to ensure that the equipment carried on it can...
