Abstract:

A correlation for the distribution of heat transfer on a nosetip with a relaminarized boundary layer is developed and implemented in a general nosetip shape change code. A sensitivity study is made that shows that relaminarization results in significantly reduced heating rates in the sphere-cone tangent region of a reentry nosetip. This locally reduced heating is expected to have an impact, not as yet quantified, on the thermostructural performance of the nosetip.
