Abstract
Payloads launched from JAXA Launch Facilities must meet JAXA safety requirements. For one, payloads having liquid propulsion systems are required to have triple seals to prevent propellant leakage.
During the past several years, JAXA System Safety Review Panel (SSRP) responsible for safety of Expendable Launch Vehicle (ELV) payloads experienced several cases of violation against this requirement. The payloads which failed to comply with the triple seal requirement were developed by the payload organizations that have launch experiences from other launch facilities but not from JAXA’s. These payloads were developed according to other safety standards and had fewer seals.
This situation triggered JAXA to examine the criteria of acceptance. As one of the activities for this purpose, JAXA performed demonstration of propellant leakage to understand the phenomena. This paper reports the findings of this demonstration.
