Abstract

Disclosed is a centrifugal type wire unwinding mechanism. The centrifugal type wire unwinding mechanism is used for supplying power for unwinding of an electric sail wire in an electric sail unwindingmechanism and providing a reliable unwinding scheme. The centrifugal type wire unwinding mechanism comprises a locking device, a bobbin device assembly, a stepping motor, the electric sail wire and adevice base. According to the centrifugal type wire unwinding mechanism, the problem that as for an existing electric sail propulsion technology, thrust is insufficient due to thin space particles issolved; the special structural characteristic of the electric sail wire can be overcome, and twisting of the wire and hooking of the wire and other satellite assemblies in the unwinding process can be avoided; and structural stability is high, and reliability and stability in the unwinding process are guaranteed.

Description

technical field [0001] The invention belongs to the field of micro-nano satellites, and relates to a centrifugal wire deployment mechanism, which is mainly used in the deployment of a slip ring device in the electric sail deployment mechanism that supplies power to the electric sail wire mechanism. Background technique [0002] In the field of micro-nano satellites, electric sail propulsion technology is a propellant-free propulsion technology. Electric sail has the advantages of no propellant, high thrust, high efficiency, low power consumption, and 24-hour uninterrupted continuous work. The electric sail propulsion system is mainly composed of electric sail wires, electron guns, and deployment mechanisms. Among them, the positively charged wires of the electric sail form a virtual sail surface through the electric field, repel the protons in the space solar wind, make it deviate from the original trajectory, and generate thrust through momentum exchange; high positive pot...
