Abstract

Liquid Natural Gas (LNG) will be used as propellant of near future space vehicle and rocket engines. Cooling characteristics of engines, especially methane thermal cracking characteristics depend on material candidate for nozzle and chamber cooling passage material temperature. This paper describes these effects on coking and sample analysis method is suggested.

Keywords : LNG, Rocket Engine, Coking
