Methods and systems for airfoil prognostics using physics-informed machine learning introduce perturbations to a nominal airfoil geometry, simulating potential faults. The perturbed airfoil geometries are processed by physics-informed neural network (PINN) models, trained on geometric and physics-based features, to predict lift coefficients, thereby predicting the health status of the airfoil. A fault probing strategy is applied to assess health status under mission-specific requirements, predicting a remaining useful life and confidence bounds for each mission-specific requirement. Efficient airfoil health prediction, including precise fault simulation, allow for proactive maintenance planning based on the predicted health status of the airfoil.
