Researchers have developed a new method for predicting the aerodynamic performance of turbomachinery cascades, which functions similarly to a CFD simulator. This framework first predicts fundamental parameters of the Navier-Stokes equations, such as temperature and pressure, and then uses these to determine key performance metrics. A novel transformer-enhanced neural operator (TNO) was introduced to improve prediction accuracy, outperforming existing deep learning operators like FNO and DeepONet on the Rotor 37 blade dataset. The TNO significantly reduces computational costs for downstream tasks like sensitivity analysis and optimization, by four orders of magnitude. AI
