A physics-based neural network for flight dynamics modelling and simulation

Abstract: The authors have developed a novel physics-based nonlinear autoregressive exogeneous neural network model architecture for flight modelling across the entire flight envelope, called FlyNet. When using traditional parameter estimation and output-error methods, aircraft models are captured about a single point in the flight envelope using a first-order Taylor series to approximate forces and moments. To enable analysis throughout the entire operational envelope, the traditional models can be extended by interpol… Show more

“…Tis method is employed to solve partial diferential equations with physical constraints or to incorporate partial diferential equations directly into the neural network learning process. For example, PINNs have been utilized to replicate 6-DoF equations of aircraft dynamics [1]. However, due to potential interference or errors in rigid-body fight data, the rigid-body dynamic model generated by the PINN method may be afected by interference, compromising its accuracy.…”
