摘要
长期以来,作为液体火箭推进剂贮箱增压用的氮气都是用高压气瓶贮存的。这种气瓶贮气系统存在体积大、质量大、增压效率低、连接面会漏气须定期检查、高压贮存不安全、需要地面供气设备、使用不便等缺点。一种新型的固体氮气发生器装置能够克服以上缺点。这种装置能实现体积小、质量小和预包装,可长期贮存,能随时产生基本纯氮气,增压效率高,不需地面供气设备,使用方便。本文介绍这种新装置的药柱配方选择,发生器设计要点,试验结果及其应用前景。
The nitrogen used for pressurization of liquid propellant tanks is usually stored in high-pressure tank. This kind of pressurization system has the following disadvantages: large volume, high mass, low efficiency, need of regular checkout to avoid leakage, unsafety of high-pressure storage, need of ground gas-supply equipment, etc. A new type of solid nitrogen generator has no disadvantages mentioned above. This generator can be prepackaged, long stored and generate pure nitrogen at any time. The grain formulation, design point, test result, and application prospect of the generator are introduced in the paper.
