Abstract

The invention relates to the technical field of high-altitude balloon accessory equipment, and discloses a foam sandwich carbon fiber flywheel and a manufacturing method thereof, wherein the foam sandwich carbon fiber flywheel includes a flywheel inner ring, a flywheel middle ring and a flywheel that are spaced apart from the inside to the outside and arranged coaxially The outer ring also includes a plurality of spokes arranged between the inner ring of the flywheel and the outer ring of the flywheel along the radial direction of the outer ring of the flywheel, and the spokes are evenly distributed along the circumference of the outer ring of the flywheel; the inner ring of the flywheel is a solid structure of carbon fiber composite material , the middle ring of the flywheel, the outer ring of the flywheel and the spokes are all hollow structures of carbon fiber composite materials, and the interior of the hollow structure of carbon fiber composite materials is filled with foam core materials; it also includes a plurality of counterweights connected to the outer ring of the flywheel, and a plurality of counterweights Evenly distributed along the circumference of the outer ring of the flywheel. The foam sandwich carbon fiber flywheel has excellent mechanical properties, and realizes the maximum weight reduction design requirement of the flywheel body structure. The foam core filling design effectively improves the torsional stiffness of the flywheel during 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 flight organization, and short test period, high-altitude balloons are increasingly favored by scientists. Usually, 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 work stably. Usually, it is necessary to use a reaction flywheel system, adjust the flywheel speed through the motor, and use the reaction torque generated by the change of flywheel angular momentum to achieve Stabilization and adjustment of high altitude balloon azimuth. [0003] At present, the large-volume high-altitude ba...
