行业：航天军工

Integrated solution for gas safety monitoring in aerospace and military industries

行业痛点

航天军工是"高密级 + 高可靠性 + 多剧毒推进剂"行业，气体风险独特：① **液氢 + 液氧发射场**：液氢储罐泄漏（沸点 -253℃）瞬间汽化扩散，遇火极易爆轰；② **联氨 / 偏二甲肼推进剂**：剧毒 + 致癌（PC-TWA 0.04 mg/m³，比光气更严苛 50 倍）+ 自燃；③ **N2O4 / 硝酸氧化剂**：刺激性强 + 与还原剂接触自燃；④ **航天器组装大厅 / 厂房**：超净环境 + ppb 级 VOC 不可有；⑤ **总装试验场 / 火箭发动机试车台**：试车瞬间排放上百吨燃烧产物；⑥ **军工弹药 / 火工品厂**：硝酸 + 硝酸盐 + RDX / TNT 蒸汽 + 防静电极严要求。监管层面：航天工业归军工保密管理 + 国家保密法 + GJB 标准（区别于民用 GB），设备需军工生产许可证 + 武器装备承制单位资格，普通商业产品无法直接采购。

## Key Monitoring Nodes

### Propellant filling area
– **Hydrazine / Unsymmetrical dimethyl hydrazine (UDMH)**: electrochemical sensor with ppb sensitivity (PC-TWA 0.04 mg/m³ ≈ 30 ppb)
– **N2O4 / Red Fuming Nitric Acid**: Electrochemical NO2 sensor with a range of 0-50 ppm
– **Liquid Hydrogen Area**: Laser remote sensing for H2 (sensitive to 1 ppm, long-range scanning up to 100m) + oxygen content
– **Liquid Oxygen Zone**: O2 Concentration (21% normal, > 23% risk of combustion assistance, < 19.5% risk of hypoxia) ### Assembly Hall / Clean Room - VOC ppb-level PID (calibrated in PPB units, targeting silicone, phthalates, formaldehyde, etc.) - AMC (gaseous molecular contaminants): silicon / boron / sodium / chlorine / sulfur ion chromatography + laser scattering - Particulate matter 0.1μm / 0.3μm / 0.5μm multi-range (ISO 14644 standard) - Temperature and humidity ± 0.5℃ / ± 5%RH ### Rocket Engine Test Bench - High-temperature products during test run: CO + CO2 + NOx + incomplete combustion VOC - Infrared thermal imaging (temperature field inversion in the testing area) - Multi-spectral laser (remote analysis of combustion products, distance 50-200m) ### Military Ammunition / Pyrotechnic Factory - HCN / nitric acid / NO2 (by-products of ammunition manufacturing) - Electrostatic monitoring (personnel wearing electrostatic discharge wristbands + anti-static clothing + grounding status of the floor) - Explosion-proof grade Ex d IIB T6 (ammunition dust environment) ## Key Technical Specifications - Explosion-proof: Ex d IIB T6 (explosive devices + ammunition) + Ex d IIC T6 (liquid hydrogen area) - Protection: IP67 (outdoor emission site) + salt spray resistance / mold resistance / moisture resistance (GJB three-proofing) - Range: Hydrazine / UDMH 0-10 ppm (ppb sensitivity) - Response time: T90 < 10 seconds (highly toxic) - Operating temperature: -55℃ ~ +85℃ (GJB military wide temperature range) - Shock resistance: 200g (GJB 150A test) - Communication: RS485 + military private network (not connected to the Internet) - Encryption: National Cryptography SM4 / SM2 ## Qualifications + Implementation Essentials 1. **Qualification of Weapon Equipment Manufacturing Unit**: This certificate is required to supply goods to the military industry system, covering both first-level and second-level manufacturing 2. **GJB 5000B Software Capability Maturity Certification**: The monitoring platform software is developed in accordance with military standards 3. **Confidentiality Qualification**: Personnel involved in the project must hold national confidentiality level 2/3, and all data must be physically isolated 4. **Lifecycle Support**: Aerospace military equipment has a lifespan of 10-15 years, significantly longer than civilian products, which typically last for 5 years. Therefore, it is necessary to provide long-term spare parts and calibration service commitments 5. **Test Run Data Archiving**: Each test run generates gigabyte-scale data, which is archived and stored for over 30 years in accordance with military requirements ## Regulatory Basis - GJB 1804A-93 "Propellant Safety Regulations" - GJB 5234A-2014 "Requirements for Qualification Review of Weapon Equipment Manufacturing Units" - GJB 150A-2009 "Environmental Testing Methods for Military Equipment Laboratories" - GB 50493-2019 Detection and Alarm Design (stricter requirements based on civil use) - China's Confidentiality Law / National Military Standard Series - ISO 14644 clean room standard (spacecraft assembly hall) ## Applicable Customers China Aerospace Science and Technology Corporation (First Academy / Fifth Academy / Eighth Academy), China Aerospace Science and Industry Corporation (First Academy / Second Academy / Third Academy / Fourth Academy), various main engine factories / design institutes of China Aviation Industry Corporation; shipyards / ordnance equipment factories of China Shipbuilding Industry Corporation; General Armament Department of the People's Liberation Army / logistics systems of the Navy / Air Force; commercial aerospace companies (Blue Arrow / Xinghe Power / Galaxy Aerospace / Zhongke Aerospace, etc.); aerospace / ordnance engineering laboratories of universities.
