FIELD: engines and pumps.SUBSTANCE: invention relates to air-engine building, namely to air turbojets. In the method of batch manufacturing of the turbojet the details are manufactured and assembly units, elements and assemblies of modules and systems of the engine are completed. The modules are assembled in minimum number of eight - from the low pressure compressor to all-mode adjustable jet nozzle. The engine is assembled module-by-module which is designed as double-circuit with two shafts. After assembly the engine is tested for gas dynamic stability of the compressor operation. Specific or three-five copies, identical for a statistical representativeness of results, taken from a lot of batch manufactured engines are tested at the bench. The bench is fitted with an input aerodynamic device with adjusting by crossing of air flow, mainly remote controlled sliding intertseptor. The intertseptor comprises the graduated scale of intertseptor positions, with the fixed critical point separating the engine by 2-5% from transition into a surge. In case of necessity the tests are repeated with the set of modes corresponding to the modes of real work of turbojets in flight conditions according to regulations.EFFECT: simplification of technology and reduction of labour costs and power consumption of turbojet test process at the phase of mass industrial production at improvement of reliability of identification of allowable range of thrust variation.11 cl, 4 dwg |
