Aero-engine starting fuel oil flow control method

The invention relates to the technical field of aero-engine starting control, and provides an aero-engine starting fuel flow control method in order to conveniently control starting fuel flow. Comprising the steps that 1, the oil supply amount and the actual rotating speed of a gas compressor corresponding to the first k periods when an engine is started are collected, and the rotating speed rate target value of the gas compressor in each control period is set; 2, calculating the oil supply increment and the rotating speed rate of a gas compressor; 3, constructing matrixes Y, X and A; 4, solving the current least square solution of the matrix A; 5, engine model parameters are obtained according to the least square solution; 6, the target oil supply amount of the next period is calculated according to the engine model parameters; and 7, repeating the steps 1-6 until the engine is successfully started. By adopting the steps, the starting fuel flow can be conveniently controlled. 本发明涉及航空发动机起动控制技术领域，为了便于对起动燃油流量进行
