OE Aerospace

Custom battery systems for use in defense applications and in space must be compact, high-capacity, robust, and 100% reliable. They need to withstand extremes of temperature, pressure, altitude, shock, and vibration, without compromising performance. We are experienced in designing and manufacturing custom pressure relief devices for applications ranging from industrial e-mobility to space exploration.

Rupture discs protect propellant tanks (fuel and oxidizers) from overpressure, isolate pressurant gas bottles until required, and enable clean, repeatable engine start sequences. Our rupture discs are leak-tight to guarantee absolute containment until failure, offer extremely rapid opening (milliseconds) for split-second reactions, and are reliable under vibration, acoustic loads, and thermal cycling.

Engine feed lines, gas generators, and igniters are subject to extreme thermal cycling, vibration, shock, and acoustic loads. Regulator failure, thermal expansion, fire exposure, or abnormal operating conditions can cause catastrophic rupture of these vital components. Our robust, leak-tight, and corrosion resistant rupture discs isolate fuel systems until activation. They support safe handling and transport of hazardous rocket fuels such as hydrazine, and protect equipment to enable clean, repeatable engine start sequences.

Cryogenic gases are used as oxidizers and for life support (LOX), as rocket fuel (LH2, LCH4), for ground support equipment (LN2), and for thermal control (LHe). We understand the specific challenges associated with cryogenic conditions and design our rupture discs to handle extreme temperatures and pressures, rapid pressure changes, and chemically reactive environments, and provide reliable, fail-safe performance.

Rupture discs for spacecraft and satellite propulsion must deliver precise, reliable performance over long mission lifetimes. They enable accurate orbital adjustment, station keeping, and attitude control while maintaining hermetic containment of pressurized systems for years or decades. With no moving parts and high burst accuracy, our rupture discs minimize failure risk and support precise mission-critical manoeuvres in demanding space environments.

From high-pressure O2 storage cylinders and emergency oxygen delivery systems to on-board oxygen generation and LOX systems, we design our rupture discs to withstand extreme pressure, temperature, vibration, and altitude changes to ensure dependable, fast oxygen delivery when crew safety is mission-critical. In ejector seats, rupture discs are used as timing, sequencing, and fail-safe pressure-release devices in the seat's gas-powered subsystems.
