Abstract

The invention relates to a cooling protection device for high-temperature flame observation of an afterburner. The cooling protection device comprises a shell, a cover plate, an observation window pressing cover and a transparent piece. The shell and the cover plate are fixedly connected through bolts. The shell is provided with a cooling water inlet, a cooling water outlet, a cable lead-out port, a cavity interior air inlet, a cavity interior air outlet and a cooling air inlet. The shell is internally provided with a cooling water pipeline, a cable pipeline, a cavity interior pipeline, a cooling air pipeline and an installing platform which communicates with the cavity interior pipeline. A baffle is arranged between the cable pipeline and the installing platform. An observation opening is formed in the side face of the shell and communicates with the installing platform. The observation window pressing cover and the transparent piece are installed at the position of the observation opening and fixed to the shell. The observation window pressing cover is provided with a ventilation hole, and the cooling air inlet communicates with the ventilation hole through the cooling air pipeline. The cooling protection device has the beneficial effects that the structure is compact, operation is convenient, work is reliable, cost is low, practicability is high, and application and popularization are easy and has high practical value.

Description

technical field [0001] The invention belongs to the technical field of engine testing, in particular to a cooling protection device for observing high-temperature flames in afterburners. Background technique [0002] When carrying out the full-state test of the engine afterburner, it is necessary to understand the dynamic combustion process and combustion conditions at the outlet of the combustion chamber during the ignition process. The existing cooling protection device cannot guarantee the safety of itself and its internal instruments when the afterburner is in full operation. Contents of the invention [0003] The purpose of the present invention is to provide a cooling protection device for the observation of the high temperature flame of the afterburner, through which the observation instrument installed inside can directly observe the dynamic combustion process and the combustion situation of the afterburner outlet during the ignition process, When the afterburner ...
