The Liquid Droplet Radiator (LDR) is an innovative high power spacecraft heat rejection concept that can be significantly lighter than conventional radiators. In the LDR concept, small droplets (100 micrometer in diameter) are sprayed into space, cooled by radiation, and collected for recirculation to the heat source. This paper reports on the initial feasibility testing of both a passive and an entrainment collector for the LDR. Tests of droplet capture efficiency indicated that passive collection is feasible, in that droplet capture losses can be limited to less than 1 part in 108 for droplet velocities applicable to a real system. In addition, the droplet loss mechanism has been identified as wave shedding, rather than rebounding or droplet breakup at the collector surface.
