Solid rocket engine modular charging technology for rapid launching

Abstract

The invention discloses a solid rocket engine modular charging technology for rapid launching. The solid rocket engine modularized power charging technology comprises the following steps that step 1,a plurality of drug blocks are decomposed according to the drug shape of a solid propellant, and a tooling mold is designed according to the sizes of the drug blocks; step 2, the solid propellant is poured into the designed tooling mold for pouring and charging, solidifying and forming are carried out, and demoulding is carried out to obtain prefabricated solid propellant blocks; and step 3, an adhesive is evenly coated between interfaces of the prefabricated solid propellant blocks, and the prefabricated solid propellant block are sequentially charged into the adhesive into an engine casing.The requirements of fast charging and fast launching of a large-scale engine are met through modular charging, the production efficiency of the large-scale solid engine is greatly improved, and the solid rocket engine modular charging technology is particularly suitable for charging tasks of the large-scale solid engine for emergency launching, temporary launching and the like.

Description

technical field [0001] The invention relates to the technical field of solid rocket motors, in particular to a modular charging process of solid rocket motors for rapid launch. Background technique [0002] With the rapid development of my country's national defense technology, aerospace systems and missile weapon systems have put forward requirements for large solid motors with higher energy, faster speed, shorter production cycle, and more convenient maintenance. Now the diameter of large solid motors has reached 3m. According to the development plan of my country's aerospace system, the diameter of the solid motor may reach 5m or even larger in the future, and the charge will increase from tens of tons to hundreds of tons. However, my country's solid engine is limited by the production process conditions. The largest solid propellant mixer in China is 2400L, with a production capacity of about 2T each time, and each production time is about 2 hours. 100 tons of powder char...

Problems solved by technology

However, my country's solid engine is limited by the production process conditions. The largest solid propellant mixer in China is 2400L, with a production capacity of about 2T each time, and each production time is about 2 hours. 100 tons of powder charges need about 100 hours (about 4 days). , the charging cycle is very long, which cannot meet the needs of rapid launch. Therefore, it is urgent to develop a fast charging process for large solid motors
