APPLICATION OF GROUND TEST DATA TO REENTRY VEHICLE DESIGN [report]

Alfred C. Thomas, Andrew Perlbachs

Methods and procedures have been developed for extrapolating ground-test aerothermodynamlc 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
