Abstract

In recent years, there has been a resurgence of interest in the development of hypersonic vehicles whose designs are significantly more sophisticated than the essentially ballistic re-entry vehicles which have been constructed and flown to date. In assessing the prediction techniques associated with the design of systems like the trans-atmospheric vehicle (TAV), the orbital transfer vehicle (AOTV), and a number of vehicles designed to be highly maneuverable at hypersonic speeds, it has become evident that there are a number of important aerothermal problems which must be addressed. Such problems include the prediction of low density non-equilibrium flows in the transition regime, the transition to turbulence at hypersonic speeds, turbulent boundary layer and shear layer development in strong pressure gradients, and the development of turbulent reacting boundary layers over ablating and transpiration-cooled surfaces. However, in both laminar and turbulent flows, the classes of problems associated with viscous/inviscid interaction or shock/boundary layer interaction represent those which create the most serious aerothermal load problems and, at the same time, are the most difficult to compute with accuracy.
