Structure gridding processing method of plume field data for formula design of solid propellant

Abstract

The invention discloses a structure gridding processing method of plume field data for a formula design of solid propellant. The method comprises the steps of: 1, plume field calculation and data storage; 2, combustion product information input; 3, structure gridding processing of gaseous product plume field data, wherein the processing process comprises the following steps of: reading gaseous product plume field data in a jet flow area, building a structure grid chart, and carrying out structure gridding processing of the gaseous product plume field data; and 4, structure gridding processing of condensed product plume field data, wherein the processing process comprises the following steps of: setting initial parameters, reading particle trajectory data, obtaining the quantity of rectangular grids at nozzle inlets of a motor, confirming upper and lower boundaries of the rectangular grids of each nozzle inlet, and carrying out the structure gridding processing of the condensed product plume field data. The method disclosed by the invention has the advantages of simple steps, reasonable design, convenience in realization, good using effect and capability of simply, conveniently and rapidly converting an unstructured grid based flow field data into a structured grid based corresponding data for subsequent calculation use.

Description

technical field [0001] The invention belongs to the technical field of solid propellant plume field data processing, and in particular relates to a method for gridding the plume field data structure for solid propellant formulation design. Background technique [0002] With the development of mechanization and information technology, more and more modern weapon systems adopt automatic tracking, control and guidance methods such as radar and photoelectricity. Combat effectiveness of projectile weapon systems. But at the same time, the harmfulness of smoke and flames during the launching and carrying of missile weapons is becoming increasingly apparent, which has a great impact on the informatization, intelligence, and stealth performance of the weapon system, and has serious consequences for the rapid, precise strike, and stealth functions of the weapon system. It has caused serious adverse effects, and has even become the main technical bottleneck restricting the normal per...
