Abstract

The invention provides an automatic control system and an operation method for a vacuum patch of a thermal insulation layer of a combustion chamber, including a large-sized temperature-controlled tank cabin, a high-efficiency vacuum protection system, a step-by-step flexible pressurization system and a full-process automatic control system; The temperature-controlled tank cabin provides the cabin space and temperature; the high-efficiency vacuum protection system provides the cabin vacuum degree; the step-by-step flexible pressurization system provides pressure for the cabin; the full-process automatic control system automatically controls the large The size and temperature control tank compartment, the high-efficiency vacuum protection system and the step-by-step flexible pressurization system are used to control and display the temperature, vacuum degree and pressure of the system, and provide real-time display alarms, reports, and record temperature after automatically matching the set parameters. Rising curve, monitoring equipment operation. The invention realizes the automatic monitoring of the whole process of forming the inner insulation layer of the solid rocket motor, and provides theoretical basis and technical support for optimizing the production process and reviewing product problems.

Description

technical field [0001] The invention relates to the field of vacuum patch of thermal insulation layer of engine combustion chamber, in particular to the field of automatic control of vacuum patch of thermal insulation layer of solid rocket motor combustion chamber. Background technique [0002] The thermal insulation layer of the combustion chamber has different technical requirements due to the different positions in the combustion chamber, the time of exposure to the hot gas and the heat flow environment. Different forming methods should be adopted for the thermal insulation layer of different formulations, the thermal insulation layer shell of different structural dimensions and different performance requirements, mainly including: compression molding, hand lay-up molding, winding molding, liquid thermal insulation material spraying and vacuum patch technology, etc. . Among them, the vacuum patch technology has the characteristics of high reliability and good quality sta...
