Abstract : A cylindrically blunted flat plate was tested in the Aerospace Research Laboratories 30-inch hypersonic wind tunnel at M = 16 and at Reynolds numbers from 3,000 to 25,000 based on leading edge diameter. The flat plate was equipped with interchangeable leading edges of 1/8, 1/4, and 1/2 inch diameter to examine this range of Reynolds numbers and to allow pressure measurements to S/D = 100. Angle of attack was varied from 0 to 10 degrees compression for the test sequence. In addition, surface pressure data were obtained on a 1/8 inch thick flat plate in the ALOSU (Aerodynamic Laboratory of The Ohio State University) 12-inch hypersonic wind tunnel at M = 10 and Reynolds numbers ranging from 600 to 1200 based on leading edge diameter. Angle of attack was varied from 10 degrees expansion to 10 degrees compression for the test sequence. (Author)
