Embodiment Construction

[0023] The principle of the invention is: the side of the engine grain and the side of the engine casing are filled with filler, which is the same as the grain produced by the wall-mounted casting process, and the grain cannot be rotated greatly during the blasting process; On the length of the grain, the tangential force and centripetal force on the grain are basically the same, and are lower than the bonding strength between the grain and the heat-insulating coating, thus avoiding the inconsistency of the force of the grain produced by the sticking casting process. The problem of broken grains. In the longitudinal direction, the structural integrity of the grain is guaranteed because the grain is under three-way compression.

[0024] The processing step of the embodiment of the present invention one is as follows:

[0025] 1. Inject the propellant into the heat-insulating sheath and vulcanize it;

[0026] 2. Freely install the grain containing the heat-insulating coating i...

Abstract

A process integrates organically advantages of free loading process and pouring along wall process used for filling powder cylinder on engine to inject filler at place between engine powder cylinder side face and engine shell so that good uniformity, high reliability and large amount of powder loading can be achieved.

Description

technical field [0001] The invention relates to a filling process of a rocket motor grain for a cannonball, in particular to a filling process for a rotationally stable rocket motor grain for a shell. Background technique [0002] In order to increase the firing range of shells and provide final guidance to shells, solid rocket motors are more and more widely used in shells. During the firing process, the shell has to withstand a high longitudinal overload acceleration of about 15,000g, and within about 0.01 second, the shell needs to increase its rotation from static to about 15,000 rpm. Therefore, the solid rocket motor used for shells not only has to withstand extremely high longitudinal overload, but also has to withstand extremely high lateral overload. The filling process of conventional rocket engine grains is generally divided into wall-mounted pouring process and free filling process. The engines produced by these two filling processes have low anti-overload abilit...
