Olali M. Integral method of diagnostics of gas turbine engines

Integral method of diagnostics of aviation gas turbine engines has been enhanced; evaluation and prognosis of technical condition of gas flow tract by use of new diagnostic parameters that enable typical fault isolation easier for conditions inbetween fully functional and failure and also identify their reasons. The developed method of statistical estimation of parameters which it is changed substantial appearance with works of engine en-ables to determine the quantitative values of parameters depending on work of concrete engine. A mathematical model enables necessary exactness to design workings descriptions of compressors gas-turbines engine depending on changes of operational factors. The considered methods allow by initial description of compres-sor to determine descriptions of compressor, which answer the actual technical state gas-turbines engine. The resulted results of approbation of the developed method of es-timation of influencing of operational factors on supply of gas-dynamic stability ofcompressors of gas-turbines engine
