Relevance of Aerothermochemistry for Hypersonic Technology

摘要: After a lull of over decade there has been, since the late 1980’s, resurgence interest in hypersonics with special emphasis on future hypersonic transport systems and associated technologies[37, 48]. The cited references contain wealth detailed information recent re-entry capsule technology[37] fundamentals aerothermochemistry their application to external internal flows relevant current technology concepts[48]. (The term ”Aerothermochemistry” was coined by von Karman 1950’s denote this multidisciplinary field study shown be pertinent then emerging aerospace era[56]. He also credited ”Aerothermodynamics” G. A. Crocco, father famous gasdynamicist L. Crocco.) There are now competing efforts from several advanced industrial countries put forward conceptual designs feasibility studies for viable (Fig. 1 [29]). Current thinking programs is based knowhow sixties progress achieved propulsion, materials avionics, last but not least CFD, inspiring fairly confident outlook ambitious R & D needed envisaged vehicles next century. In order make these technologies efficient, economical environmentally sound, an essential aspect It vital need better understanding control complex physico-chemical processes occurring such configurations flow fields, wakes propulsion systems.
