Control of the technical condition of the compressor of the TV3-117 gas turbine engine to change the reserve of its gas-dynamic stability

Abstract

The article presents the results of the analysis of changes in the state of the compressor of the TV3–117 engine from the time of operation and the angles of installation of its guide apparatus. The proposed method of recognition of technical condition of the compressor is a complex thermodynamic parameter - the ratio of the stock of gasdynamic stability using the method of small deviations. The results of gas tests of the gas turbine engine, with the nominal and "degraded" characteristics of the compressor according to the proposed method.
