RHEA(Reentry Heating Energies Analyzer),
Abstract
At the present time, duplication of reentry environments in ground test facilities cannot be satisfactorily accomplished. Major deficiencies in such facilities are: too short test times, gases not representative of the atmosphere because of residual dissociation and ionization of air molecules, and stagnation pressure and enthalpy not representative of those produced through dynamics of the flight vehicle. Many new concepts and attempts to circumvent these limitations have been studied over the past few years. The RHEA process is a novel mechanic approach to solving the problem of duplicating high speed environments in ground testing facilities. This report reviews highlights of the concept and research results on key problems which have been under investigation by a number of research groups for the past year. (Modified author abstract)
