A plugging cover for the inlet port outlet of a solid rocket ramjet engine

Abstract

The invention belongs to the integrated rocket ramjet engine design technology and relates to a solid rocket ramjet engine inlet outlet outlet plug. It is characterized in that it consists of a metal grid [1] and a non-metallic wedge combination [2] bonded to the metal grid [1]. The invention does not require the missile itself to provide any conversion signal during the working mode conversion process, but automatically completes the conversion action; the inlet and the ram nozzle will not be damaged during the conversion process; it has good safety, reliability, stability and synchronization. .

Description

A plugging cover for the inlet port outlet of a solid rocket ramjet engine technical field The invention belongs to the design technology of an integral rocket ramjet engine, and relates to a blocking cover for the outlet of an air inlet of a solid rocket ramjet engine. Background technique The integrated solid rocket ramjet has been widely used in the recent development or improvement of medium and long-range air-to-air missiles in the world's advanced countries due to its advantages of high energy, simple structure, reliable operation, and convenient maintenance and use. The inlet outlet plug is an important part of the solid-impact engine, which acts as a link between the booster engine and the main engine, and is related to whether the engine can work normally. According to foreign reports, an ablative plug is used for the outlet plug of the intake port, and the ablative plug is made of an ablative material, and the plug is ignited by an igniter when the working condit...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the ablative plug needs to provide an ignition signal, and in the process of ignition and ablation, it is easy to damage the air inlet, which poses a safety hazard

A certain type of domestic product adopts an integral inlet outlet plug, which is applied to a circular inlet. The outlet plug has a large size and heavy weight, and it is easy to damage the ram nozzle when thrown out.
