Abstract

The invention discloses an aero-engine airborne model speed measurement and time consumption data analysis method, which comprises the steps: operating an airborne model on a controller of an aero-engine, starting the iterative calculation of the airborne model when the controller starts the engine, and outputting a starting mark level; writing a code before the start of operation of the airborne model and a code after the end of operation of the airborne model into a level flipping instruction, and enabling the controller to output flipping levels when executing the level flipping instruction in each control period; respectively collecting a starting mark level, the flipping level and a control period count, and obtaining time consumption of the airborne model in each control period by adopting a flipping timing algorithm; and adopting a repeated search counting algorithm to obtain controller time consumption distribution of a full control period, and selecting a period of which the time consumption exceeds a preset time.

Description

technical field [0001] The invention belongs to the field of aero-engine control system testing, in particular to a method for speed measurement and time-consuming data analysis of an aero-engine airborne model. Background technique [0002] The control system is the "nerve center" of the engine. Aeroengine modeling technology is one of the most important computer simulation technologies for aeroengines. The aeroengine model can be applied to the field of fault-tolerant control of the engine control system, and it is the task of the advanced aeroengine control system. It can provide support for improving reliability and safety; it can be used in the engine health management system, laying the foundation for the development of engine gas circuit diagnosis; it can be applied to optimization control fields such as online thrust optimization control and emergency control; it can be used in semi Physical and in-loop verification tests. Therefore, in the development and applicati...
