Example Embodiment
[0037] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0038] A preferred embodiment of the present invention provides an aero engine fuel heating test method, which is used for heating test control of the fuel supplied to the external fuel system of the aero engine to meet the fuel heating test requirements of the aero engine. In the existing PID heating test control, by adjusting the working time of the heating unit, the outlet fuel temperature reaches the preset heating value. However, as the engine test status changes, the outlet fuel temperature changes greatly, resulting in dynamic heating control The response time and transient control accuracy cannot meet the heating test requirements. In this embodiment, the fuel flow monitoring of t...
