“…These phenomena impact performance characteristics such as the lift and drag of a body, or the dynamic response of a control system. Historically, in aircraft design, these unsteady effects have required additional analyses to mitigate undesirable aeroelastic effects such as wing flutter and undesirable stall characteristics, among other issues [1][2][3]. Sometimes the unsteady effects are beneficial, e.g., when using leading edge extensions (LEX) to improve high angle of attack performance [4].…”

This paper is concerned with the development and testing of advanced time-stepping methods suited for the integration of time-accurate, real-world applications of computational fluid dynamics (CFD). The performance of several time discretization methods is studied numerically with regards to computational efficiency, order of accuracy, and stability, as well as the ability to treat effectively stiff problems. We consider matrix-free implementations, a popular approach for time-stepping methods applied to large CFD applications due to its adherence to scalable matrix-vector operations and a small memory footprint. We compare explicit methods with matrix-free implementations of implicit, linearly-implicit, as well as Rosenbrock-Krylov methods. We show that RosenbrockKrylov methods are competitive with existing techniques excelling for a number of problem types and settings.

“…Por otra parte, conseguir que los aviones de combate embarcados tengan unas capacidades operativas equiparables a la de sus homólogos terrestres es una tarea muy compleja [78], que en la práctica obliga a tener que plantear el diseño del avión prác-ticamente desde los orígenes, y de manera radicalmente distinta. Este es un proceso también muy caro, extenso y complejo.…”
