This paper addresses the development and application of transient mathematical models and the in-house simulation code for the KRE-75 engine, which will be used as the 1st and 2nd stage engines of the Korea Space Launch Vehicle II. KRE-75 is the first Korean open-cycle liquid rocket engine that uses kerosene and liquid oxygen as propellants. Most of the components comprising the KRE-75 and the priming process of propellants in the propellant feed lines are considered. Startup and shutdown simulations of the KRE-75 are compared with engine ground test results and discussed in detail. The simulation results show good agreement with the test results, proving the validity of the transient mathematical models and the simulation code.
