Treatment system for engine gas jet tail flames

Abstract

The embodiments of the invention provide a treatment system for engine gas jet tail flames used for treating the gas jet tail flames injected by an engine. The engine includes a jet pipe used for gasexpansion and speed increase. The engine gas jet tail flame treatment system includes a cooling device and a supporting device. The cooling device includes at least one introduction module and at least one treatment module. The materials of the introduction module and the treatment module are ice. An introduction channel is arranged in the introduction module. A treatment channel is arranged in the treatment module. The introduction channel is opposite to the jet pipe. The supporting device and the cooling device are connected to each other and is used for supporting the cooling device. The engine gas jet tail flame treatment system can make the cooling device have high temperature reducing and cooling efficiency for the gas jet tail flames, and can make the cooling device have remarkableeffects on deceleration, noise reduction and harmless treatment of the gas jet tail flames.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a treatment system for engine gas jet exhaust. Background technique [0002] With the in-depth development of space exploration activities, more and more rocket engines have been put into use. However, in addition to obtaining the huge propulsion required for space activities through rocket engines, people also suffer from the pollution and damage to the ecological environment brought by their tail flames. For example, during the ground thermal performance test or launch process of the rocket engine, the super high temperature (generally 3000°C, the highest temperature can reach 3500°C) and the super high speed (2-3 Mach, the general speed is 1500m / s ~ 5000m / s), ultra-high energy (MJ / kg level, generally 6 ~ 7MJ / kg) gas jet plume, and ultra-high speed also brings huge noise. Especially the solid rocket motor, except that its gas jet tail has the aforementioned characteristics, ...

AI Technical Summary

Problems solved by technology

The amount of water required to inject water into the gas jet tail flame is extremely large, forming a large amount of mixture of gas and steam. In severe cases, the test engine will be burned due to channel congestion, causing damage to the equipment of the test and launch sites and the surrounding ecological environment.

In addition, the existing engine gas jet plume treatment system is not only complex in system, high in energy consumption, high in use and maintenance costs, but also difficult to treat harmful components in the gas jet plume
