Abstract

The invention provides an aircraft engine fuel simulation control system and its adjustment method. The system includes a system pressure adjustment pipeline, a dynamic flow simulation pipeline, and a fuel consumption pipeline; various regulating valves on the pipeline are used for flow regulation and simulation . The present invention is a system with simple operation and high parameter accuracy, which can not only simulate the fuel consumption of the engine alone, but also combine the fuel consumption and provide a set of dynamic flow, and is suitable for simulating the fuel consumption of various types of engines. The inspection function can carry out the self-circulation work of the equipment before the joint test with the system to verify whether it can reach the working state.

Description

technical field [0001] The invention relates to the field of aircraft engine control systems, in particular to an aircraft engine fuel simulation control system and an adjustment method. Background technique [0002] With the expansion of a certain type of aircraft fleet and the continuous increase in flight hours, many problems and failures have been exposed to the fuel system during field operations. [0003] There are many defects in the existing engine fuel simulation control system. For example: the dynamic flow pressure is displayed by a pointer pressure gauge, and due to the rough switch adjustment, the dynamic flow pressure and flow are unstable, which makes the pressure display error larger. In addition, the original analog system only has pressure display, no flow information, and cannot be accurate Simulate the real working state of the engine, so the functional verification of the fuel system cannot be performed qualitatively and can only be used quantitatively....
