介绍了液滴辐射器的研制情况。重要的出版成果，以前的研究人员，目前正在进行的工作进行了讨论。几个建议的LDR配置进行了描述，目前最感兴趣的矩形和三角形配置进行了检查。讨论了液滴发生器、收集器和辅助部件的研制。被认为是一个液滴片的辐射性能，实验结果被认为是在非常好的协议与分析预测。液滴片中的液滴的碰撞，由空间等离子体的液滴的充电，以及大气阻力对液滴片的影响被示出是很小的后果，或可以通过适当的设计被最小化。LDR被认为比常规技术更不易受微流星体或敌对威胁的影响。还确定了在有关轨道环境中稳定的工作流体。讨论了将航天器污染从LDR减少到可接受水平的方法。微重力测试的液滴发生器的初步结果。未来可能的NASA和空军的任务增强或启用LDR也进行了讨论。系统研究表明，LDR的质量可能低于热管散热器。计划在航天飞机或空间站上进行微重力测试被认为是LDR发展的下一个合乎逻辑的步骤。
Development of the Liquid Droplet Radiator (LDR) is described. Significant published results of previous investigators are presented, and work currently in progress is discussed. Several proposed LDR configurations are described, and the rectangular and triangular configurations currently of most interest are examined. Development of the droplet generator, collector, and auxiliary components are discussed. Radiative performance of a droplet sheet is considered, and experimental results are seen to be in very good agreement with analytical predictions. The collision of droplets in the droplet sheet, the charging of droplets by the space plasma, and the effect of atmospheric drag on the droplet sheet are shown to be of little consequence, or can be minimized by proper design. The LDR is seen to be less susceptible than conventional technology to the effects of micrometeoroids or hostile threats. The identification of working fluids which are stable in the orbital environments of interest is also made. Methods for reducing spacecraft contamination from an LDR to an acceptable level are discussed. Preliminary results of microgravity testing of the droplet generator are presented. Possible future NASA and Air Force missions enhanced or enabled by a LDR are also discussed. System studies indicate that the LDR is potentially less massive than heat pipe radiators. Planned microgravity testing aboard the Shuttle or space station is seen to be a logical next step in LDR development.
