Construction and Testing of a Table-Top Shock Tunnel

Abstract

A new table-top shock tunnel (TTST) has been constructed and is intended to allow rapid and low-cost measurements of shock-layer chemistry and material response in well-characterized high-velocity flows. The TTST is based on the production of pulsed hypersonic molecular beams by laser detonation in a conical nozzle. In addition to providing fundamental data for the development of models, the production of controlled shock layers above ablating and non-ablating surfaces and the measurement of their phenomenology provide a means to validate new models. Furthermore, material response can be tested in realistic environments and aid in the development of materials for hypersonics applications. Initial characterization of the TTST has been carried out by studying the ablation phenomenology of a Kapton H polyimide surface exposed to a hypersonic O/O2 beam
