Liquid working media laser plasma micro propulsion and target supply device

Abstract

The invention discloses a liquid working medium laser plasma micro propulsion and target supply device. The liquid working medium laser plasma micro propulsion and target supply device is of a rotating disc structure capable of continuously supplying targets and ablating the targets, and mainly comprises a reusable transparent and hard substrate disc carrier rotating disc, a big driving motor, a reusable transparent and hard substrate disc, a small driving motor, a liquid working medium storage tank, a duct, a liquid working medium flow valve, a laser transmitter, a battery used in cooperation with the transmitter, a spraying nozzle, a sliding rail and a cable. The liquid working medium target supply device is combined with the characteristics of a solid working medium target supply device. Due to the adoption of surface-shaped targets, the utilization rate of the working medium targets can be obviously improved. Due to the adoption of the reusable transparent and hard substrate disc carrier rotating disc, supplying and consumption of target materials can be simultaneously conducted, a micro propulsion system can continuously work, and most possible propulsion effect can be provided.

Description

technical field [0001] The invention belongs to a small power propulsion device suitable for orbit changing and orbit maintenance of on-orbit spacecraft. Background technique [0002] The existing propulsion targets can be divided into solid working fluid and liquid working fluid according to the phase state of the working fluid. The main difference between the two phases lies in the way of supplying the target. Solid working fluid is easy to process, and can be made into linear targets and planar targets. The target supply method can be divided into target tape winding type, wire winding type, and target disk type. The working mode of the liquid working medium is relatively simple. The commonly used method is extrusion, which squeezes out a certain flow of liquid working medium and ablates it completely, and then performs the next target supply.
