Abstract
A pulse plasma thruster (,) utilizes a vapor producing solid (,) and a micro-sized heater (,) to produce a high pressure vapor that is directed into an ignition chamber (,) and to a thrust discharge chamber (,). The thrust discharge chamber (,) comprises two oppositely disposed electrode plates (,) and oppositely disposed fuel propellants sources (,). The passageway (,) leading from vapor producing solid (,) to the thrust discharge chamber (,) is configured to permit uniform feeding of the vapors to the thrust discharge chamber (,). A pair of electrode terminals (,) extend from the electrode plates (,) and through a housing (,). A power source (,) is coupled to the terminals (,) and provides the ignition signals necessary to cause a spark and a breakdown to a useful plasma arc by controlling the voltage-current shape of the ignition signal.
