Abstract

To avoid an unexpected explosion occurring from a mixture of LOx and fuel, Inter-Propellant Seal (IPS) is used in a Turbopump. This paper presents a brief theoretical backgrounds of IPS and also reports preliminary test results. Tests were performed up to 1.5 MPa and 20,000 rpm and leakage performance of IPS was evaluated. As a result it was verified that leakage flow rate of IPS satisfied its design requirement.
