Abstract
A pulsed plasma thruster (PPT) and a method of making the PPT are disclosed. The PPT includes no moving parts and can be made in a small size. The PPT can achieve long operating duration by using vapor as a fuel. Liquid used to form the vapor can be easily stored and can provide an ample supply of vapor. The PPT is also designed to facilitate easy and rapid manufacture. The process for making the PPT uses known techniques for making printed circuit board devices.
