摘要

Well-polished surfaces of satellites like solar panels and antennas occasionally reflect sunlight directly toward theEarth and cause "satellite flare", which can be observed from the ground. The typical example of this kind of flare isknown as "Iridium Flare" caused by Iridium communication satellite constellation. Although these flares areunintentional phenomenon, causing satellite flares intentionally anywhere at any time may be useful forentertainment and advertising purposes. Therefore, the concept of "active flare satellite constellation" is proposedhere. An active flare satellite is the medium-sized satellite and is equipped with a reflective mirror as well as a pulsedplasma thruster (PPT). The mirror can be steered by an actuator so that observers on the ground can enjoy the flaresfor a long period of time. The flares can be colored by a color filter attached to the mirror. Also, a liquid crystal panelcan add blinking effects to the flares. By operating multiple active flare satellites as a constellation, simple geometricpatterns and alphabets can be expressed and this, so called "space bulletin board" may be utilized in many ways suchattractions in theme parks, advertising and optical communication. With the aim of forming the active flare satelliteconstellation and maintaining it against disturbances such as air resistance and J2 gravity effect, pulsed plasmathruster is adopted for its capability to control the thrust digitally and minutely. The main topic of this study is todevise a new type of pulsed plasma thruster which is highly durable enough to operate the constellation and provideflare services consequently. Several types of configurations and supplying methods of Teflon propellant as well asthruster structures are experimentally tested in this study in order to realize continuous supply of the propellant andtherefore a long period of operation.
