Passive Nosetip Technology (PANT) Program. Volume 22. Coupled Erosion/Ablation of Reentry Materials

Abstract

A study of coupled erosion/ablation effects in flight and ballistic range environments is conducted with the objectives of identifying and quantifying the sources, magnitudes and consequences of uncertainties associated with the data and phenomenology on which shape change calculations are based. The interactions of the phenomena of temperature dependent single impact mass loss and erosion induced augmented heating as key elements within the morphology of coupled effects are investigated. A test plan consisting of complimentary single impact and ballistic range experiments is presented in which the material samples, the impacting particle, the impact velocity and the thermal state of the material is closely matched.
