Abstract

The present RCS of hydrazine used for controling rockets has a weak point on its toxicity. The present project focuses on the non-toxic property of methane and develops safer RCS system for the future rockets.

Reasons for using JSS2

The present computation needs more than 10 species reactive computation, so that the computational cost is very large. In addition, a massive parametric study will be conduted to find the optimal way of injection. Thus, using supercomputer is necessary.
