An implicit-explicit flux vector splitting scheme which can be used in both explicit and implicit calculations is proposed and applied to a hypersonic thermochemical nonequilibrium flow problem. Since the consistency of these calculations must be remarkably good, the effort to make the present computational code has been greatly reduced. In this paper, consequently the numerical algorithm of the present scheme is weightedly explained.
