Abstract Rocket sleds belong to a category of large-scale test platforms running
on the ground. The applications can be found in many fields, such as aerospace
engineering, conventional weapons, and civil high-tech products. In the present
work, shock-wave/rail-fasteners interaction is investigated numerically when the
rocket sled is in supersonic flow conditions. Two typical rocket sled models are
considered, i.e., an anti-D shaped version of the rocket sled and an axisymmetric
slender-body variant. The dynamics for Mach number 2 have been simulated in
the framework of a dynamic mesh method. The emerging shock waves can be
categorized as head-shock, tailing-shock and reflected-shock.… More >
