The effects of model scale on the fluctuating pressure environment in a region of spike-induced flow separation have been investigated. Data for 40 percent and 100 percent wind tunnel models are compared with flight results. The separated region was found to increase in size with increasing Reynolds number even though the Reynolds number at reattachment was always turbulent. Furthermore, critical Reynolds number effects in the flow recirculation region caused the most severe fluctuating pressure on the spike to shift to the leeward side. Evidence of the excitation of a fundamental breathing mode of the spike-induced flow separation was observed on a second flight. (Kursetz)
