Abstract

The invention relates to an aero-engine exhaust measuring device, which belongs to the technical field of aero-engine tests. The aero-engine exhaust measuring device provided by the technical scheme comprises a measuring section and a measuring rake. The measuring section is cylindrical, and the measuring rake is installed on the inner wall of the measuring section. The measuring rake comprises ameasuring rake body, a total pressure probe, a static pressure probe, a temperature probe and a clamping plate. The measuring rake body is of a sheet-shaped structure. A groove is formed in the surface of the measuring rake body. The signal detection ends of the total pressure probe, the static pressure probe and the temperature probe penetrate through the groove and penetrate out of the measuringrake body, and the signal output ends of the total pressure probe, the static pressure probe and the temperature probe penetrate out of the outer wall of the measuring section and are connected witha signal receiving device. The equipment is widely applied to the field of aero-engine tests.

Description

technical field [0001] The invention belongs to the technical field of aero-engine testing, and in particular relates to an aero-engine exhaust gas measuring device. Background technique [0002] Aviation engine test refers to the experiment that uses special test and testing equipment to test the performance, reliability and durability of the engine. Aeroengines work under extremely harsh conditions such as high temperature, high pressure, high speed and high load. In order to ensure the reliable operation of the engine and its system, various strict tests must be carried out. [0003] During the test run of an aero-engine, it is necessary to measure exhaust parameters, including exhaust temperature, total pressure, static pressure, etc. Existing aero-engine exhaust measuring devices and measuring rakes are generally applicable to the measurement of large-caliber engines (more than 900mm in diameter) exhaust. For example, the Chinese patent application with publication num...
