Abstract

MACLUCAS, D  and  GLEDHILL, IMA. Time-accurate transonic CFD Simulation of a generic store release case. R&D j. (Matieland, Online) [online]. 2018, vol.34, pp.9-16. ISSN 2309-8988.

Store release from a parent aircraft in the transonic regime is a complex transient interaction to simulate, due to both compressibility effects and the strong interference flow field generated between the parent and store bodies. This work presents the results from a time-accurate transonic numerical simulation of a generic store release case, with detailed attention to ejector force profiles. Confidence limits for time-accurate trajectory calculations with STAR-CCM+® have been improvedfor this standard benchmark case.

Keywords : Store separation; store integration; CFD; time-accurate.
