Dynamic stall often causes unsteady loads and negatively affects the aerodynamic performance of aircraft. Thus, accurate modeling dynamic stalls is crucial for aircraft design. With development machine learning, existing data-driven models always rely on extensive, costly training data but lack physical knowledge, which limits their generalizability interpretability. Therefore, this study proposes a data-knowledge-driven procedure. First, by exploring damping evolution moment coefficient, three distinct patterns are identified. A transitional state, significantly differs from both deep light stall, proposed to assist neural network modeling. Subsequently, with P-based degree classification force component developed, integrates Leishman–Beddoes model. This model provides unified approach predict aerodynamics across different degrees stall. Compared purely network, incorporating expert knowledge improved generalization accuracy 50%. Moreover, insights reduce reliance high-precision network.
