TL;DR: In this article, a simulation tool for the simulation of unsteady manoeuvres of a single-tailed delta-wing aircraft is presented, which can simulate both controlled and free-to-roll manoeuvres, at various angles-of-attack, as well as static flight conditions.

TL;DR: The unstructured, time accurate flow-solver TAU is coupled with a computational module solving the flight-mechanic equations of motion and a structural mechanics code determining the structural deformations.

TL;DR: The SikMa project as discussed by the authors developed and validated a numerical tool to simulate the unsteady aerodynamics of a free flying aero-elastic combat aircraft, by use of coupled aerodynamic, flight mechanics and aeroelastic computations.

TL;DR: The simulation platform described in this article is one of two investigated variants in the DLR project SikMa and is characterized by the use of a multibody system (MBS) to account for the elastic structure as well as the flight mechanics and its loose coupling to the computational fluid dynamics (CFD) software.
