Solutions de sécurité pour l'industrie spatiale
Les installations de lancement manipulent de grandes quantités de gaz hautement inflammables et explosifs. Les arrête-flammes installés sur les conduites de ventilation des réservoirs de stockage de carburant empêchent qu'une source d'inflammation externe, telle que la foudre ou une décharge d'électricité statique, ne provoque une explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. vers les principales réserves de carburant.
During static fire tests, engines are operated at extreme conditions. Flame Arresters Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. in vapor recovery systems, propellant feed lines, and venting systems ensure that local anomalies or “hard starts” cannot drive a flame front back into test infrastructure.
Modern spacecraft and satellites rely on high‑energy lithium‑ion batteries and complex electronics. In the event of thermal runaway, flame arresters integrated into battery enclosures allow gases to vent safely without allowing flames to propagate to adjacent systems.
Spacecraft propulsion and life‑support systems require controlled pressure Pressure (gauge pressure) Pressure for which the value is equal to the algebraic difference between the absolute pressure and the atmospheric pressure. equalization. Flame Arresters act as breather elements in vent and exhaust lines, allowing gas flow while containing any accidental ignition within localized compartments.
In defense‑related space applications, such as interceptors and tactical missiles, lightweight metal‑foam Flame Arresters provide effective thermal and flame containment without adding significant mass or impacting the flight profile.
