Multiple-Body Trajectory Calculations Using the Beggar Code

Store Release Trajectory Variability from Weapon Bays Using Scale-Adaptive Simulations

“…The initial part of the trajectory, controlled by the ejector forces compared closely to wind tunnel data, however, after about 0.3s the pitch and yaw rate started to drift away from wind tunnel data. This behaviour over time, especially in pitch rate and attitude, was also reported in previous studies [22,28,29].…”

“…The pitch and yaw curves showed a slight divergence from the wind tunnel data after about 0.3 seconds of the release. This divergence over time was not only observed in the original study by Fox [21], but in other studies [22,28,29] as well.…”

“…Several studies have utilised this test case, using structured [22,23,24,25], unstructured [26,27,28,29,30,31] and meshless solvers [32], to validate the prediction of the store trajectory, making it a popular validation case. The test provided pressure data for a geometrically simple wing and store under mutual interference as well as a realistic trajectory.…”

A Comparison of Approaches to Multi-Body Relative Motion using the Kestrel Solver

“…The wing-pylon-store (WPS) dataset is a comprehensive collection of experimental measurements obtained by the Arnold Engineering Development Complex (AEDC) for the purposes of validating computational fluid dynamics (CFD) simulations [3]. The wing-pylon-store has been the subject of several CFD comparisons over the years, including Lijewski and Suhs [4], Prewitt et al [6], Eymann et al [1], Loupy et al [5], and Prior et al [7]. These studies include both Euler and RANS simulations and, in general, the rotational displacements showed a greater sensitivity than the linear displacement to the simulation setup.…”

Theoretical Modeling of Two-Body Interaction in Supersonic Flow

“…They, however, provide useful data sets for verification of theoretical, semiempirical, and computational tools. Computational fluid dynamics (CFD) has been the main approach for the aerospace engineer and designer in obtaining aerodynamic characteristics of multibody configurations [9][10][11][12]. Yet, despite the power of CFD, challenges still exist to predict drag, lift, and other quantities rapidly enough for conceptual design.…”
