Abstract

The invention belongs to a mounting structure of a high-temperature gas pressure measuring sensor, aims to solve the technical problems in the prior art that when a pressure measuring sensor is used for measuring the pressure of a combustion chamber, the pressure measuring sensor is prone to inaccurate measurement and even measurement failure due to the fact that the installation space is limitedand the measuring environment is severe, and provides a thermal protection mounting structure for a pressure measuring sensor in narrow space. The thermal protection mounting structure comprises a supporting base, a pressure measuring guide pipe and a hoop. The upper part of the supporting base is an L-shaped fixing plate, and the lower part is a supporting base; one end of the supporting base isconnected to the bottom of the fixing plate, and the other end is fixed to the wall of the combustion chamber. The hoop is arranged on the outer side of the pressure measuring sensor in a sleeving mode, and the hoop connector is installed on the side wall of the fixing plate; one end of the pressure measuring guide pipe is connected with the detection end of the pressure measuring sensor, the other end is communicated with the interior of the combustion chamber, and the middle of the pressure measuring guide pipe is coiled and the pressure measuring guide pipe bypasses the supporting base.

Description

technical field [0001] The invention belongs to the installation structure of a high-temperature gas pressure measuring sensor, and in particular relates to a thermal protection installation structure of a pressure measuring sensor in a narrow space. Background technique [0002] The chamber pressure of the combustion chamber is one of the key telemetry parameters of the engine, and the measurement of this parameter can reflect whether the engine is working normally. According to the requirements of engine measurement and overall structural layout, the chamber pressure measurement point must be selected in the body of the combustion chamber, and the pressure measurement sensor must be arranged in the fairing nearby. Due to the large number of instruments and equipment in the fairing, the available space for the pressure sensor is very limited, and the environment is harsh. The wall temperature of the body of the combustion chamber is not lower than 700°C, the temperature of ...
