Passive Nosetip Technology (PANT) Program. Volume 9. Unsteady Flow on Ablated Nosetip Shapes - PANT Series G Test and Analysis Report
Abstract
As an ablating nosetip progresses through its trajectory, its surface shape changes continuously. Among the many shapes it may assume, there are some for which the flow field is grossly unsteady, in which the flow field pulsates with a high frequency. Such shape induced flow field instabilities may seriously compromise the realization of flight objectives, possibly even resulting in structural failure of the nosetip. This report describes the results of an experimental and analytical effort directed toward improving prediction procedures for identifying instability onset and, ultimately, the magnitude and frequency of the pressure fluctuations.
