Embodiment Construction

[0021] In order to have a further understanding and understanding of the features, purposes and functions of the present invention, the design concept of the present invention will be described below in conjunction with specific embodiments, so as to understand the characteristics of the present invention, the detailed description is as follows:

[0022] The laser micro-propulsion device based on nanofluid micro-droplet working medium mainly includes a thruster housing, a working medium cabin, an auxiliary gas storage tank, microfluidic components and nanofluid working medium.

[0023] The thruster shell adopts a low aerodynamic resistance shape design of a rotating parabola. The inner surface of the shell is arranged with high-reflectivity mirrors at intervals. The mirror surface is coated with a super-hydrophobic coating to prevent the jet fluid from adhering to the mirror surface and causing a decrease in mirror reflectivity. The micro-thrust is generated by the reaction for...

Abstract

The invention discloses a laser micro-propelling device and method based on nanometer fluid micro-droplet work mediums. The device comprises a thruster shell body, a work medium cabin body, an auxiliary gas storage tank and a microflow control assembly; the auxiliary gas storage tank and the work medium cabin body adopt an integrated design, and the auxiliary gas storage tank is communicated withthe work medium cabin body through an adjusting valve; the work medium cabin body is tightly connected with the thruster shell body, and the microflow control assembly penetrates through the work medium cabin body and the thruster shell body; the auxiliary gas storage tank is communicated with the microflow control assembly; the work medium cabin body is communicated with the microflow control assembly. Generation and manipulation of nanometer fluid micro-droplets are achieved through the microflow control assembly; focusing of incidence laser beams is achieved through a reflecting mirror of the inner surface of the thruster shell body, the nanometer fluid micro-droplets enhance absorption of irradiation laser and causes intensive crushing, and a counteractive propelling force is generatedon the surface of the thruster shell body. Structural integration and functional characteristics are remarkable, selection of the propelling work mediums is unique, and correspondingly the laser micro-propelling device has the propelling effects of high specific impulse, a high impulse coupling coefficient and high energy conversion efficiency and meanwhile makes a propelling process controllable.

Description

technical field [0001] The present invention relates to a new type of laser micro-propulsion device and method, in particular to a laser micro-propulsion device using nanofluid micro-droplet working medium, which can be used as a vehicle for orbital aircraft maneuvering, space transportation, and space debris removal. important means. At the same time, the system can also play an important role in the field of unmanned detection of deep space in the future. Background technique [0002] Low cost, high reliability and fast maneuvering have always been the development direction of aerospace propulsion technology. Laser propulsion, with its two outstanding features of complete separation of energy and working fluid, and energy and aircraft, makes it possible for the propulsion system to simultaneously obtain ideal thrust and high specific impulse for the first time. [0003] The selection of working fluid (target material) has always been one of the important research content...
