Abstract

This study proposes the development of tabletop experimental setup and imaging diagnostics to study the flow physics of hypersonic vehicle and to characterize the damage behavior of high-speed impacts. In this work, by modifying the instrumentation of laser-launched flyer setup used extensively to shock compress energetic samples, we generate shockwaves in gas by driving the metal foils to hypersonic velocities. The proposed setup is capable of tailoring shockwaves in various gaseous mediums by punching out foils of different metals as flyers over a range of velocities (1-7 km/s) in environments of choice. A key aspect of our instrumentation is the development of orthogonal line of sight diagnostics to study shock wave structure in-line and perpendicular to the direction of shock transit. This work focuses primarily on the development of flow field imaging using high-speed Shadowgraph and Schlieren imaging over other diagnostics. Additionally, a necessary level of insight can be attained within the framework of the numerical model to facilitate the interpretation of shockwaves and associated flow fields. In future, the setup will be extended to study high-speed impacts involving debris such as micro-meteoroids and dust particles with hypersonic vehicles and space stations for the development of shielding materials, and the interaction of hypersonic flow fields with micron-sized fuel droplets dripped by a custom-built droplet generator to study detonation wave propagation and interactions with aerosolized fuel droplets. In this work, results of high-speed impact test, the details of the instrumentation and preliminary imaging data will be presented.
