Description

technical field [0001] The invention belongs to the field of laser propulsion, and in particular relates to an energy-containing liquid laser-enhanced propulsion device based on microfluidic technology. Background technique [0002] Laser propulsion technology is a new type of propulsion technology based on the principle of intense laser-matter interaction. Laser propulsion technology is divided into reflective and transmissive. The current research focuses on the transmission laser propulsion technology, and its working medium is divided into two types: solid and liquid. Among them, the liquid has good energy density, and the energy supply can be adjusted according to the needs. [0003] However, the liquid working fluid has the disadvantages of working fluid splashing and low specific impulse under the action of laser, and GAP (polyazide glycidyl ether) can overcome these problems, improve the specific impulse, and solve the working fluid splashing to a certain extent H...
