In this paper, scale-adaptive simulation is used to study store tra-

Multi-disciplinary Simulations of Stores in Weapon Bays using Scale Adaptive Simulation

“…For CFD comparisons, run S2 is employed as it is the longest signal, and it agrees with the over-sampled signal S1 obtained two years earlier [24]. Past works [2,16] were using signal S3 for comparison with CFD, and for this reason, the envelope, and peak values appear to be slightly different than what is shown in figure 11.…”

“…Statistical convergence is tested using the maximum of the normalised difference between the average of n+1, and n trajectories defined as in reference [16]:…”

“…In earlier work [16], the AGARD case [32] for external store release was used. Over all available data for store release from cavities, experiments performed at the Arnold Engineering Development Center (AEDC) [33] are at conditions closer to the present computations, and have been selected for validation.…”

“…For this reason SAS is also used in the present work. The 6DoF method is presented in reference [16]. Only the aeroelastic method used for store deformations is shown here.…”

“…This section is the continuation of the work presented in reference [16] where twenty store release simulations were performed with the store modelled as rigid. This paper goes further adding the aeroelasticity to the complete store.…”
