摘要
第二动力系统(SPS)是承担关键任务的复杂机载系统。以美军装备为例分别介绍了典型的机械传动SPS、气压传动SPS和电气传动SPS并对三者的优缺点进行了总结,回顾了美军与国防承包商的SPS研发历程并分析了它们的技术特点,总结了先进SPS的四项关键技术,简要介绍了SPS的应用拓展并对SPS的发展趋势进行了展望。指出了未来先进SPS的四大主要技术特点:多电化架构、高功能集成度、能量综合、优化利用能力以及与主发动机的协同增效。
Secondary power system(SPS) is a complicated airborne system which undertakes varieties of key tasks.Three typical SPSs of mechanical link,pneumatic link and electric link types were introduced with examples of U.S.fighters,and their advantages and disadvantages were summarized.The research on SPSs developed by U.S.force and defense contractors was reviewed and analysis on technical feature of these SPSs was conducted.Besides,four key technologies in advanced SPS were summarized and the extended applications of SPS were briefed.Finally,the development trend of SPS was prospected.Four key technical characteristics of advanced SPS in future were presented:multiple electric architecture,high integration of structure,comprehensive utilization capability of onboard energy and synergies between main engines and itself.
