Abstract

The invention provides an aircraft engine fuel oil simulation control system and an adjusting method. The system comprises a system pressure adjusting pipeline, a moving flow simulation pipeline and an oil consumption pipeline. Various adjusting valves on the pipelines are utilized for flow adjustment and simulation. According to the invention, the system is simple to operate and high in parameter precision, can individually simulate fuel oil consumption of an engine and also provide a set of a moving flow through combination with the fuel oil consumption, is applied to simulation of fuel oil consumption of various types of engines, also has a self-check function, and can carry out equipment self-loop operation before a joint test with the system so as to verify whether an application state can be reached.

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....
