Problems solved by technology

The non-metallic protective panel is a component that directly bears the tail airflow. It is generally made of composite materials and can withstand higher temperatures, but its strength is worse than that of steel. In case of damage to the protective panel, it is not conducive to the reusability of the deflector
In severe cases, the rocket wake can penetrate the non-metal protective panel and metal panel, causing the overall damage and failure of the deflector

Embodiment Construction

[0036] pass below Figure 1 to Figure 10 As well as listing some optional embodiments of the present invention, the technical solutions (including preferred technical solutions) of the present invention are further described in detail. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] Such as figure 1 and figure 2 As shown, the general composition of the deflector: metal frame 1 and non-metallic panel 2. The metal frame 1 of the deflector is in the form of a plate shell, and a metal panel 3 is arranged between the metal frame 1 and the non-metallic panel 2 . The metal frame 1 is mainly welded and formed by metal plate parts such as a vertical large triangular support plate 1.1, a beam 1.2, a transv...

Abstract

The invention discloses a flow guider with a self-protection characteristic. The flow guider with the self-protection characteristic comprises a metal frame and a panel, wherein a flow guide profile is formed on the metal frame, and the panel covers the flow guide profile. The flow guider with the self-protection characteristic is characterized in that a water box and a water pump are arranged inthe metal frame; a plurality of water outlet holes are formed in the panel; a water inlet port of the water pump communicates with the water box; and the plurality of water outlet holes communicate with a water outlet port of the water pump through a pipeline separately. The flow guider with the self-protection characteristic is capable of effectively lowering a temperature of scouring a flow guide surface by a wake flow of a rocket, reducing an ablation effect of the temperature of the wake flow on a nonmetal protection panel, and effectively alleviating the impact damage of granular gas flowresidues on the nonmetal protection panel.

Description

technical field [0001] The invention belongs to the technical field of deflectors, and in particular relates to a deflector with self-protection characteristics. Background technique [0002] When the rocket is launched, the high-temperature and high-speed airflow ejected from the nozzle at the tail of the rocket will affect all kinds of equipment in the surrounding area below. When the solid rocket is ignited and launched, the airflow is also mixed with solid particles such as gunpowder, which is accelerated by the airflow. The destructive power of the airflow in the tail of a rocket engine. In order to protect these devices from being damaged, deflectors are needed to guide the airflow generated by the rocket engine in a specified direction [0003] The deflector is usually composed of a supporting metal body and a high-temperature resistant non-metallic protective panel, and the two are mainly fastened together by bonding. The non-metallic protective panel is a componen...
