Electrostatic Switchable Appliqué

Abstract

In this paper, the development of a second generation electrostatic radiator (ESR) is described. This device consists of a different operational structure and materials than the first generation ESR. The second generation ESR employs a less insulating membrane than the previous device. Additionally, the insulator has been moved from the membrane to the rigid substrate. This construction results in significantly reduced operating voltages compared to the first generation device. The construction also permits easier fabrication which permits the device to be applied to the spacecraft as an appliqué. This paper discusses the current state of development of the ESR appliqué, its construction and results from laboratory thermal vacuum performance testing.
