A Free-Flight Investigation of Ablation of a Blunt Body to a Mach Number of 13.1
Abstract
A five-stage rocket-propelled research-vehicle system was flown to a maximum Mach number of 13.1 at altitude of approximately 78,000 feet to determine ablation characteristics of Teflon in free flight. Continuous in-flight measurements were made using sensors developed by the National Aeronautics and Space Administration. The sensors were located on the blunted face of a nose cone constructed from Teflon, with one at the stagnation point and two others at a surface distance of 0.62 radius on opposite sides of the stagnation point. The ablated-length measurements were in close agreement with analytical predictions. The analytical predictions, upon inclusion of the pertinent material-property values, should be applicable to other materials as well as Teflon.
