AI Technical Summary
In turboshaft engine modeling, the lack of measured data and insufficient modeling conditions leads to inconsistencies between the characteristic diagrams and design point parameters and the simulation object, resulting in low model accuracy and difficulty in meeting engineering application requirements.
By constructing a component-level model of the turboshaft engine, solving the equilibrium equations and establishing the constraint equations, optimizing the model using a Kalman filter, and combining the measured data to solve the model, a baseline model of the turboshaft engine is constructed.
With limited measured data, the model accuracy was improved, the accuracy problem caused by inconsistencies between characteristic maps and design point parameters was solved, and a baseline model that can be applied in engineering was constructed.
