METHOD OF OPERATIONAL DEVELOPMENT OF EXPERIMENTAL GAS-TURBINE ENGINE Russian patent published in 2015 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: invention relates to air-engine building, namely to air gas turbine engines. The experimental double-circuit, two-shaft GTE is subjected to operational development. Operational development of GTE is performed step by step. At each phase from one to five GTEs are tested for compliance with the pre-set parameters. Any of damaged in tests or in inappropriate conditions module - from low pressure compressor up to an all-mode adjustable jet nozzle comprising an adjustable jet nozzle and the rotary device detachably fastened to afterburner the rotation axis of which is designed rotated with reference to the horizontal axis at minimum angle 30° is studied and in case of necessity is replaced by reworked ones. The program of tests with the subsequent finishing reworking includes tests of the engine for identification of influence of climatic effects on the change of operational performance of experimental GTE. Tests are performed with measurements of engine parameters at various operating conditions within configured range of flight modes for particular engine range to reference measured parameters to standard atmospheric conditions with due allowance for variation of working body properties and geometric characteristics of engine air-gas channel.

EFFECT: improvement of GTE performance, namely traction and reliability of the engine by operation in the full range of flight cycles in various climatic conditions, and also in simplification of technology and reduction of labour costs and power consumption of GTE test process at the phase of operational development of experimental GTE.
