Abstract
Two-dimensional and axisymmetric, inviscid, hypersonic flows about simple slender bodies are considered with particular reference to pressure distributions and shapes of shock waves. Approximate solutions, based on blast analogy, are derived and compared with more exact, theoretical calculations and with experimental results. The validity of correlation parameters predicted by the blast analogy and the range of their applicability are investigated. Near- exact theoretical results available for real airflow at Mach numbers from 15 to 19 are compared with the perfect gas data.
