Abstract:

Tests were conducted in a hypervelocity track facility to establish the ablative characteristics of the heatshield material for the NASAAmes Galileo Probe. Data were obtained from eight shots at launch velocities ranging from 15,850 fps to 17,950 fps. Six of the shots were conducted through an argon environment. The test required the nosetip to be recovered intact. Measurements were made of the model velocity and in-flight surface temperature. A description of the test unit, test article, and test technique is presented herein. Author
