Methods and procedures were developed for extrapolating ground-test aerothermodynamic data to flight conditions for four geometric elements. These elements are a sharp unyawed delta wing, deflected control surfaces in compression and expansion, surface roughness elements typified by shallow convex surface waves and rectangular grooves, and a yawed circular cylinder intersecting a sharp flat plate. Graphs and charts are provided for rapid numerical computation of factors to be used in extrapolating the wind-tunnel data for these geometric elements to flight conditions. An evaluation of the simulation capabilities of operational hypersonic ground facilities is also included.
