Abstract

The invention discloses an engine parameter determination method and device, equipment and a storage medium, and belongs to the technical field of aviation control. The method comprises the steps of obtaining current parameter prediction data of a simulation model corresponding to an engine based on previous parameter prediction data through an intelligent optimization algorithm; predicting the validity of the parameter prediction data based on a validity prediction model; and under the condition that the prediction result is that the parameter prediction data is valid, according to a comparison result between the actual working scene data of the engine and the output data of the parameter prediction data based on a simulation model, determining whether the parameter prediction data is parameter target data of the engine or not. According to the technical scheme, the number of times of evaluating illegal parameters is reduced, and the engine model proofreading efficiency is greatly improved.
