I. Main Applications of Nitrogen in Aerospace
1.Environmental Simulation and Testing
• Spacecraft Simulation: High-purity nitrogen creates oxygen-free, dry testing environments to prevent material oxidation or moisture damage during spacecraft R&D.
• Engine Combustion Tests: Nitrogen simulates high-altitude hypoxic conditions, supporting engine ignition stability and combustion performance validation.
2.Fuel System Protection
• Fuel Tank Inerting: Nitrogen injection into aircraft fuel tanks or rocket propellant chambers reduces flammable gas concentrations, preventing explosions or fires.
• Fuel Line Cleaning: Pre-launch purging with high-purity nitrogen ensures fuel lines are free of impurities and moisture.
3.Equipment Maintenance and Operation
• Hydraulic Shock Absorption Systems: Nitrogen-filled hydraulic devices in aircraft landing gear prevent oil oxidation or "dieselization," enhancing shock absorption efficiency.
• Tire Inflation: Nitrogen replaces air in aircraft tires, avoiding rubber aging, corrosion, and friction-induced ignition during braking.
4.Safety and Risk Mitigation
• Emergency Inflation Systems: Nitrogen pressurizes aircraft slides and life rafts for rapid, non-flammable deployment during emergencies.
• Electrical System Protection: Nitrogen maintains inert atmospheres in electrical equipment during short-term shutdowns, preventing moisture- or oxidation-related failures.
II. Advantages of On-Site PSA Nitrogen Generation Systems
1.Efficiency and Flexibility
Rapid Response: Gas supply available within 20 minutes of startup, adapting to urgent or dynamic nitrogen demands.
2.Environmental Compatibility
Low Energy Consumption: Core energy use relies on air compressors, with no hazardous emissions, aligning with green aerospace standards.
3.Reliability and Safety
• Ultra-High Purity: PSA systems produce nitrogen exceeding 99.9995% purity, eliminating contaminants that could harm fuels or electronics.
• Stable Supply: Supports continuous 24/7 operation with consistent gas quality.
4.Adaptability and Customization
• Tailored Solutions: Customizable flow rates, pressures, and remote monitoring capabilities to match aerospace base requirements.
• Extreme Environment Deployment: Skid-mounted designs enable rapid setup in complex, confined spaces, meeting launch site demands.
Nitrogen’s inert, non-flammable, and stable properties are critical to aerospace applications. PSA on-site nitrogen systems enhance mission reliability and cost-effectiveness through efficient, flexible, and safe gas supply. As technology advances, PSA systems are poised to become indispensable infrastructure in the aerospace industry.
