Normal Force and Pitching Moment Trend Sensing of Delta Wing Based on Flow Physical Topology with Sparse Pressure Measurements

Abstract

AbstractAt high angles of attack (AOAs), aircraft experience significant nonlinear aerodynamic forces, which are influenced predominantly by vortex structures. These unsteady forces and moments have a considerable impact on aircraft maneuverability and ...Practical ApplicationsModern aircraft frequently require significant angles of attack during line-of-sight combat operations. The swift variation in attitude angle triggers an immediate shift in the adjacent flow field, making the aircraft susceptible to ...
