Relevant Projects
Launch vehicle propulsion systems
Steelhead’s high-performance composite overwrapped pressure vessels (COPVs) are integrated into launch vehicle propulsion systems where weight, reliability, and pressure containment are mission-critical. These vessels are engineered to withstand extreme acceleration, vibration, and thermal cycling, ensuring consistent fuel or oxidizer delivery during ascent. Their lightweight construction contributes to improved payload capacity and fuel efficiency—key metrics in commercial and government launch programs.
Spacecraft propulsion tanks
For orbital and deep-space missions, Steelhead provides custom-designed COPVs that serve as primary or auxiliary tanks for spacecraft propulsion systems. These vessels are built to operate in vacuum and microgravity environments, with materials and liners selected for compatibility with hypergolic, cryogenic, or pressurized gas propellants. Their proven performance in long-duration missions supports satellite station-keeping, orbital maneuvering, and interplanetary propulsion.
Flight-critical breathing oxygen
Steelhead’s small-format pressure vessels are used in life-support systems for both crewed spacecraft and high-altitude aircraft. These tanks are certified for oxygen service and designed to meet stringent aerospace safety standards. Their compact, lightweight form factor makes them ideal for integration into ejection seats, pilot breathing systems, and emergency oxygen supplies—where reliability under pressure is non-negotiable.
Lightweight one time use pressure vessels
In applications such as stage separation, pyrotechnic actuation, or emergency system deployment, Steelhead supplies single-use COPVs that are optimized for weight and performance. These vessels are engineered for precise burst or discharge characteristics and are often used in expendable systems where every gram counts. Their design balances cost-efficiency with aerospace-grade quality, making them ideal for mission-specific use cases.
