Abstract: Systems, methods, and non-transitory computer-readable media are disclosed for automatically generating aircraft models by modifying quantitative design variables based on joint analysis of aerodynamic, structural, and/or energy performance. For example, in one or more embodiments, disclosed systems iteratively modify ailerons and a propulsion system based on performance criteria until a balancing metric converges. The disclosed systems then determine performance metrics corresponding to the aircraft model with the modified ailerons and propulsion system, such as stresses and deflections under performance load, a measure of aeroelastic stability, and a battery performance metric. The disclosed systems can then modify design variables based on the determined performance metrics to explore the design space and generate a new aircraft model.

Abstract: Systems, methods, and non-transitory computer-readable media are disclosed for automatically generating an improved aircraft wing by modifying quantitative design variables of one or more airfoils based on joint analysis of aerodynamic and structural performance. In particular, the disclosed systems determine cross-sectional aerodynamic and structural performance metrics for identified airfoils. Based on cross-sectional metrics, the disclosed systems iteratively determine wing aerodynamic performance and deformation metrics across a span of the wing until arriving at an equilibrium deformation and corresponding aerodynamic metric. The disclosed systems can repeatedly analyze the aero-structural metrics for different quantitative design variables to explore a design space and generate an improved wing design while improving aerodynamic and structural performance.
