Modular forming method of deflector

Abstract

The invention discloses a modular forming method of a deflector. The method comprises the first step of forming of a splicing module, the second step of forming of an internal frame, the third step offorming of a peripheral structure, the fourth step of installation of a metal panel, and the fifth step of installation of a non-metal panel. A modularized metal pipe is adopted to construct the internal frame of the deflector for a rocket engine, the internal frame is connected with the metal panel, a bottom plate and a top cone part in a riveted or threaded more to form an integral structure through adapter connection of side plates on the periphery of the internal frame, and finally the non-metal panel and the metal panel are connected together through a bonding method. The problems of deformation and internal stress caused by welding and forming of a metal thin plate adopted in a traditional machining method of the deflector are solved.

Description

technical field

[0001] The invention relates to the technical field of flow directors, in particular to a method for modularizing a flow director. Background technique

[0002] When the rocket engine is ignited, it is necessary to use the deflector to guide the high-temperature and high-speed airflow ejected from the rocket engine in a certain direction to prevent the uncontrolled airflow from causing damage to the surrounding objects and the rocket itself. The main components of the deflector used in the rocket engine include the main body, the metal panel and the non-metallic panel (ablation-resistant layer). Among them, the metal panel and the non-metallic panel must meet the specified profile shape to meet the deflector requirements.

[0003] The traditional manufacturing method of the deflector is to make the main part (such as figure 1 As shown, the spliced ​​metal sheets including the longitudinal ribs 10, the transverse ribs 11, the bottom plate 6, and the top cone ...
