双级压缩气源起动装备关键技术研究与实现

Research and Realization on Crucial Technology of Two-stage Compression Air Starting Equipment

为了填补国内气源起动装备的技术空白,研发具有自主知识产权的气源起动装备,立足于我军大型飞机较高压力、超大流量的气源起动保障需求,创新设计了以双级无油螺杆压缩为核心技术的供气系统工艺流程,解决了超大流量气源二次升压的核心技术难题;辅之采用板式散热器多点浮式支撑、冷却与旋转分离除水、多机组设备优化起动等技术,突破了超大流量气源风冷散热、高温除水以及多机组设备联轴同步起动等关键技术难题,使得装备总体性能优于国外同类进口产品。

In order to fill the domestic technical bank and own the independent intellectual property rights of air starting equipment,based on the higher-pressure and large-flow air starting security demand of large aircraft,this paper innovatively designed the process of gas supply system that takes two-stage non-oil screw compression as core technology,which solves the core technology problem of the super flow source＇s second boosting pressure. Additionally,the newly-developed equipment adopted the panel radiator＇s multi point floating support technology,cooling and rotating water-separation technology,and multi unit equipment＇s optimizing start technology,which breaks through the key technology problem of the super flow source＇s air cooling,high temperature water removal,and multi unit equipment＇s synchronous start. Through the above design,the newly-developed equipment＇s overall performance outgoes the similar foreign imports of equipment.
