The new generation of designs presents a wide range of configurations and approaches to exploit the advantages of these vehicles that can be used in civil, commercial, and military applications. One of the more popular concepts is the tandem tilt-wing e-VTOL configuration. However, these types of VTOL configurations bring challenges for performance prediction during crucial parts of flight operations. The flight dynamics during transition regimes where the vehicle transitions from vertical to forward flight and vice versa is not fully understood. In this paper, modified blade element momentum theory (BEMT) is used to analyze the blades on NASA's LA-8 testbed prototype tandem tilt-wing UAM. The method proposed finds the important parameters of the propeller performance i.e., thrust, normal force and torque coefficients of the complete propeller system at a range of tilt-angles from 0 to 90 degrees. Results are compared to wind tunnel experiments with the identical propeller, conducted in the ODU Low-speed wind tunnel lab. Surrogate models were created using Gaussian process models to decrease the required computational resources for simulations. 收起
