Abstract

The invention discloses a composite measuring rake and relates to the field of aero-engines to solve the problems that a conventional measuring rake made of a steel-rubber composite material is heavyin weight and that temperature measuring points and dynamic pressure measuring points are difficult to replace. The measuring rake comprises a rake body made of a carbon fiber composite material, a pre-embedded member and a plug member. The pre-embedded member is disposed inside the rake body. The plug member is disposed at the tail end of the rake body. The pre-embedded member is provided with ameasuring point group at one end away from the rake body. A wire tube communicating with the measuring point group passes through the pre-embedded member and extends into the rake body to be connectedwith the plug member, wherein the measuring point group is configured to test the transient temperature and the pressure of an air flow.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a compound measuring rake. Background technique [0002] In the flight test, the temperature and pressure parameters at the inlet outlet / engine inlet provide important information for evaluating engine performance, and the measuring rake is used as a test auxiliary equipment, installed at the place to be tested, to obtain relevant test parameters, and then evaluate through measurement Flow field quality. [0003] According to the needs of large-size air inlet measurement, it is usually required to arrange 8 measuring rakes in the shape of "meter" at equal angles in the circumferential direction. In addition to requiring that the blockage ratio of the flow path occupied by the rake body is ≤6%, the weight of the measuring rake, the test There are more and more requirements on the composition of parameters. [0004] Currently selected steel + rubber composite measuring rakes, the weig...
