Title Design for space pulse spraying Anti-Satellite Weapon warhead
Abstract
Aim at soft-damaged technology of space war, this paper designed a space pulse spraying ASAT warhead. By establishing the model of spatial orientation of spray painting, giving the relevant parameters for the classical interior ballistic calculation. At the same time, the expansion of rarefaction wave technique is introduced, comparing with the expansion of rarefaction wave internal ballistic model, to find ways to reduce the recoil. Introduce the occurrence of liquid physical phenomenon in vacuum environment, and based on ANSYS software, simulate the key process—the outflow field of nozzles with different shapes and liquids of different viscosity with dynamic finite element method, summarize the relevant conclusions and provide the help for the engineering development of the spraying soft kill anti-satellite ammunition.
Keywords Space pollution Interior ballistic Nozzle simulation.
