Aircraft dynamic thermal load identification and prediction method and device

The invention belongs to the technical field of aircraft thermal management systems, and particularly relates to an aircraft dynamic thermal load identification and prediction method and device, and the method comprises the steps: S1, carrying out the sampling in a thermal load range of each state stage inputted under a flight envelope, forming a plurality of thermal load sample data, and enabling each thermal load sample data to comprise a plurality of thermal loads; s2, heat exchanger cold edge working medium parameters corresponding to all the thermal loads are determined through simulation; s3, extracting a plurality of input sequence data from each piece of thermal load sample data, and training a pre-constructed thermal load identification prediction LSTM network model based on the input sequence data; and S4, predicting the cold edge working medium parameters of the heat exchanger under the flight envelope to be predicted based on the trained thermal load identification prediction LSTM network model to
