Optical fiber conduction heating flexible ejection device and ejection system and method thereof

Abstract

The invention discloses an optical fiber conduction heating flexible ejection device, an ejection system and an ejection method thereof, the optical fiber conduction heating flexible ejection device comprises an energy conversion cavity and an optical fiber output head capable of transmitting laser to the energy conversion cavity, and an energy conversion medium capable of absorbing laser energy and converting the laser energy from a liquid phase to a gas phase is injected into the energy conversion cavity; the energy conversion cavity is communicated with a trajectory, the trajectory direction does not coincide with the laser incident direction, the trajectory is filled with a to-be-ejected object, and the to-be-ejected object can block the trajectory and eject out from an ejection outlet of the trajectory; according to the invention, the energy conversion medium can be converted from a liquid state to a gas state in the energy conversion cavity by laser irradiation, so that the air pressure in the energy conversion cavity can be increased, an object to be catapulted can be catapulted from the catapulting outlet of the trajectory, and the flexible catapulting motion is completed; the energy of the laser is almost completely absorbed by the energy conversion medium in the energy conversion cavity, and the energy conversion efficiency and the energy utilization efficiency can reach higher levels.

Description

technical field [0001] The invention relates to the technical field of lasers and special applications, in particular to an optical fiber conduction heating flexible ejection device, an ejection system and an ejection method thereof. Background technique [0002] The temperature of 1g of water rises by 1°C and absorbs 4.2J of heat, while at 101kPa, 1mol H at 100°C 2 The volume of O is 1molH at 0°C 2 The volume of O has increased by about 1700 times. Therefore, the pressure change caused by the gas-liquid phase change of water can be used for steam ejection. At present, conventional steam catapults need to be equipped with steam storage tanks, pipelines and auxiliary equipment, volume and weight. Too large; the steam catapult consumes a lot of steam when it is working, and the energy loss during ejection is large; the adjustment range of the ejection force of the steam ejection is small, and it cannot eject lighter drones; thus, this kind of steam ejection mechanism cannot b...
