The Pressurant Tanks from IHI Aerospace are Space-Qualified Storage Tanks engineered for spacecraft and satellite propulsion systems, supporting mission requirements with tank volumes from 3 to 1494 liters. Designed to comply with stringent global aerospace standards including MIL-STD-1522A, JAXA, NASA, and ESA, these tanks deliver the high reliability, safety, and long-term performance required for critical orbital and deep-space missions.
Available in spherical and tear-drop configurations, these spacecraft pressurant tanks integrate advanced propellant management devices (PMDs) such as diaphragms, bladders, vanes, surface-tension channel meshes, start baskets, and sponge metal structures. These internal architectures enable precise fluid acquisition, pressure regulation, and stable propellant behavior in microgravity, making them ideal for demanding satellite attitude control and propulsion subsystems.
Built using titanium alloys, aluminum, and CFRP/aluminum composite materials, the tanks combine lightweight construction with exceptional mechanical strength and pressure containment capability. Each unit undergoes extensive qualification processes including stress analysis, dynamic vibration testing, leak-before-burst (LBB) verification, and flow growth analysis, ensuring robust performance under launch loads, thermal cycling, and in-orbit operating conditions.
With proven flight heritage and mission-tested reliability, IHI Aerospace pressurant tanks are optimized for satellite platforms, spacecraft propulsion architectures, and mission-critical pressurization systems, where efficient propellant storage, fluid stability, and structural integrity are essential for mission success.
