Abstract

The invention discloses an engine air intake pressure field quality automatic judgment method and device. A test data file to be analyzed is read, wherein the test data file includes the actually measured index value of an engine air intake pressure field measured in the test; the quality index value of each main pressure field and the maximum distortion area range corresponding to the quality index value of each main pressure field are calculated according to read test data file to be analyzed and the preset test parameters; and the standard situation of the quality of the engine air intake pressure field is judged according to the calculated quality index value of each main pressure field and the preset quality design index value of each main pressure field and the rule list. According to the engine air intake pressure field quality automatic judgment method and device, the time consumed for judging the pressure field quality can be greatly reduced, the pressure field analysis efficiency can be greatly enhanced and the optimization design of the substandard pressure field test piece can be greatly facilitated.

Description

technical field [0001] The invention relates to the field of engine detection, in particular to a method and device for automatically judging the quality of an engine intake pressure field. Background technique [0002] During the operation of an aviation gas turbine engine, the quality of the intake pressure field will greatly affect the performance of the engine, and in extreme cases it will cause the compressor to stall or even surge. There are many indicators for judging the quality of the pressure field, such as the total pressure recovery coefficient σ, the regional distortion index DCP, the circumferential annular pressure distortion index IDC ring, the radial annular pressure distortion index IDR ring, the 60° sector distortion index DC60, the circumferential total Pressure distortion index IDC, etc. Usually, it is necessary to use experimental methods to obtain the original pressure field data. Designers can select one or several indicators as the focus target acco...
