From page 86...
... The hypersonic program offices should establish liaisons with these activities to promote their applications to hypersonic vehicles. The tremendous heat loads that will be a natural part of hypersonic flight, together with the uncertainty of the heat transfer properties of new materials when combined in a specific design configuration, lead to the possibility of broad uncertainties in the thermal environment for key information/control equipment, including cables and hydraulics.

... , Those high performance materials that have been identified as having significant structural properties at the high temperatures of interest, and their ranks thin as temperatures rise, do not have an adequate data base, nor are their failure mechanisms adequately understood, nor do we know their ability to maintain adequate properties for the necessary times at elevated temperature to insure a design with the necessary structural integrity for the intended missions.

... 3.S The Role of CFD 1) CFD has become a principal tool for aerodynamic and propulsive-flow design of hypersonic vehicles because computers can simulate simultaneously the hypersonic flight parameters of velocity, free stream density, physical scale, and free stream thermochemical state.

... 5) - Current CFD simulations of the intense aerodynamic heating for shock on cowl lip shock conditions agree well with experimental results, but both results correspond to the lower altitude portion of the hypersonic fight corridor where shock thickness is negligible.
