Abstract

The invention relates to the technical field of aero-engine numerical control systems, and particularly discloses an engine numerical control system full-working-condition semi-physical test system which comprises a main fuel oil back pressure simulation device used for comparing the pressure of a main combustion chamber with the collected pressure behind a main fuel oil real nozzle, according to the difference value between the pressure of the main combustion chamber and the collected pressure behind the main fuel real nozzle, a pressure adjusting signal behind the main fuel real nozzle is generated; and the afterburner back pressure simulation device is used for comparing the afterburner pressure with the collected pressure behind the afterburner real nozzle and generating a pressure adjusting signal behind the afterburner real nozzle according to the difference value between the afterburner pressure and the collected pressure behind the afterburner real nozzle. The invention further discloses a full-working-condition semi-physical test method for the engine numerical control system. According to the full-working-condition semi-physical test system for the engine numerical control system, the integrity verification of the performance of the numerical control system can be realized.

Description

technical field [0001] The invention relates to the technical field of aero-engine numerical control systems, in particular to a semi-physical test system of an engine numerical control system under all working conditions and a semi-physical test method of the engine numerical control system under all working conditions. Background technique [0002] The semi-physical test of aero-engine numerical control system takes the control system as the actual object, simulates the real working environment of the engine numerical control system through physical effects, and verifies the function and performance of the control system. The nozzle part adopts the equivalent nozzle to simulate the maximum state of the real nozzle of the engine. The pressure and flow under other working conditions cannot meet the requirements under this equivalent nozzle, which makes the performance of the numerical control system in the semi-physical environment and the real engine state have a certain dif...
