The Ablation Characteristic of an Electrothermal Pulsed Plasma Thruster

The electrothermal pulsed plasma thruster (PPT) has the adva ntage of better efficiency compared with a traditional electro magnetic PPT under the low power level condition. It has gre at potential for the application of micro satellite. The ablation process is a dominant process during the PPT operation and it has a huge influence on the output parameters.
