摘要：如果没有热管理方面的同步进步，电子设备小型化的进步所带来的海军/国防部航天器有效载荷能力的潜在增加就无法实现。越来越多的散热电子设备必须紧密地封装在较小的体积中，以与其他子系统竞争有限的航天器真实的资产。“在最近的一项研究中，未来海军航天器的热需求预计约为今天的十倍。目前最先进的技术根本无法满足这一需求。因此，NRL的航天器工程部（SED）获得了外部赞助，在2007财年启动了一项研究和开发工作，以寻求一种氨无轴承泵，该泵使热控制子系统（TCS）能够将其热传输能力提高至少十倍，同时保留其他操作属性（例如，可靠性和长寿命）。
Abstract : The potential increase in payload capability of Navy/DoD spacecraft resulting from advances in electronics miniaturization cannot be realized without concurrent advances in thermal management. More and more heat-dissipating electronics have to be packaged tightly in a smaller volume to compete with the other subsystems for limited spacecraft "real estate." In a recent study, projection for the thermal requirement of future Navy spacecraft is about ten times that of today. Current state-of-the-art technologies simply will not meet this demand. Accordingly, NRL's Spacecraft Engineering Department (SED) acquired external sponsorship to initiate a research and development effort in FY2007 in pursuit of an ammonia bearingless pump that enables the Thermal Control Subsystem (TCS) to enhance its heat transport capacity at least tenfold while retaining other operational attributes (e.g., reliability and long life).
