Abstract
ExplodingWire-Pulsed Plasma Thruster (EW PPT) is the satellite thruster using a wire explosion. Wire explosion is the phenomenon that wire is exploded by thermal expansion due to low-voltage pulse current from capacitor bank. The produced expansion gasses after exploding a wire contribute as propulsion of thruster. But, it is not clear about wire explosion with low-voltage, low-vacuum state and short Al thin wire. The purpose of this paper is to record the phenomenon by using HPV-1 and measure impulse bit by pendulum. As a result, impulse bit (I_<bit>) is 2900μN・sec with the wire of Al which diameter is 0.2mm.
