FIELD: engines and pumps.SUBSTANCE: invention relates to air-engine building, namely to air turbojets. The air turbojet is designed as double-circuit, two-shaft one and contains a jet nozzle attached to a rotary device with a possibility of execution jointly with a mobile element of the latter of rotations for change of the traction vector direction. The rotation axis of the rotary device with reference to the horizontal axis is turned to the minimum angle 30° clockwise for the right engine and to the minimum angle 30° counterclockwise for the left engine. After assembly the engine is tested for influence of climatic conditions at the main characteristics of the compressor operation. Tests are performed with measurements of engine parameters at various operating conditions within programmed 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 quality of operational characteristics of TJE due to implementation in the engine of set of main modules and assembly units with the technical solutions developed in the invention, parameters and at the expense of less energy and labour consuming obtaining and more correct reduction of experimentally received engine parameters to the parameters, corresponding to standard atmospheric conditions, and also in increase of representativeness of results of tests for the full range of flight cycles in various climatic conditions.8 cl, 2 dwg, 4 tbl |
