Title:
AERO ENGINE FUEL CONTROL SYSTEM AND FUEL METERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/159903
Kind Code:
A1
Abstract:
An aero engine fuel metering device. The fuel metering device (2) comprises: a linear displacement sensor (21); and a validation curve memory unit, respectively in communication connection with the linear displacement sensor (21) and an engine electronic controller (3) of an aero engine fuel control system. The validation curve memory unit is configured to store a validation curve, and the validation curve is used for representing the relationship between adjusting and recording the voltage of the linear displacement sensor (21) and the fuel demand of an engine; after the engine electronic controller (3) is energized, the engine electronic controller (3) reads the validation curve stored in the validation curve memory unit, such that the validation curve in the engine electronic controller (3) is maintained consistent with the validation curve in the validation curve memory unit. An aero engine fuel control system, comprising the fuel metering device (2) and the engine electronic controller (3), and further comprising a fuel pump (1) and a fuel nozzle (4), the fuel metering device (2) being respectively connected to the fuel pump (1) and the fuel nozzle (4). The system has a validation memory function and a certain intelligent function, can maintain the consistency of the validation curve and eliminate the difference, thereby improving the matching and further improving the performance of the engine.
