Abstract

We have accelerated thin PVC foils by ablating the foil material in an electrothermal shock tube with power fluxes of typically 2 × 10⁴ W/cm² and 160 μs duration. The measured burn velocity, blow off velocity, and terminal velocity compare well with steady flow hydrodynamic considerations and a simple rocket model.
