Abstract

The invention discloses a turbo engine complete machine test run method and an engine test run device. The engine test run device comprises a vehicle station, a torsion measuring device, a dynamometer, a flywheel, an operating system, a PEC simulator and a controller. The vehicle station is provided with a turbo engine. The torsion measuring device is connected with the power output shaft of the turbo engine to measure the torque of the turbo engine. The dynamometer is connected with the torsion measuring device to measure the power of the turbo engine. The flywheel is connected with the dynamometer to simulate the rotational inertia of a propeller. The operating system issues an operating signal. The PEC simulator is electrically connected with the dynamometer and the operating system to convert the operating signal into corresponding rotation speed and torque information and transmit the rotation speed and the torque information to the dynamometer. The controller is electrically connected with the turbo engine and the operating system to issue a corresponding control command to the turbo engine according to the operating signal. According to the invention, test run control and test run measuring of the turbo engine are realized.

Description

technical field [0001] The invention relates to the technical field of aeroengines, in particular to a method for testing a complete turboprop engine and an engine testing device. Background technique [0002] Due to the complex structure of the turboprop engine, high performance and functional requirements, the test operation and control are all new methods, and there is relatively little experience that can be used for reference. Therefore, when the complete machine test run of the turboprop engine is realized on the test bench, it is very difficult to ensure the safe and stable operation of the engine. At the same time, the "General Specifications for Aviation Turboprop and Turboshaft Engines" (GJB242) requires aviation turboprop engines to determine the performance characteristics of the complete engine equipped with power absorption devices, and to verify manual feathering, reverse propeller work, stability. [0003] Therefore, it has become a major technical problem ...
