Heat-Transfer Tests on a 14-Percent-Scale Model of the NASA-MMC Viking Mars Entry Vehicle at Mach Number 16
Abstract
The Viking Mars Lander vehicle is to be protected during the Martian entry by a 70-deg half-angle, spherically blunted, conical heat shield designated as the aeroshell. The aeroshell surface contains several surface features (protuberances and cavities) associated with mechanical fittings and entry instrumentation. Heat-transfer rates in the vicinity of such features are known to be significantly affected, with local heat-transfer-rate amplification being dependent on the feature geometry and the flow environment. The test program described was initiated to verify the adequacy of the design criteria for the aeroshell and base cover heat shields.
