Electrothermal <strong>Systems</strong><br />
- 56-<br />
Electrothermal <strong>Systems</strong>, where the propellant (gas) is heated by passing over an electric<br />
heated solid surface (resis<strong>to</strong>jet) or by passing it through an arc discharge (arcjet).<br />
The heated gas is then accelerated by a gas-dynamic expansion in a nozzle. Typical<br />
applications of this principle are the monopropellant hydrazine operated Power Augmented<br />
Catalytic Thruster (PACT) and Hydrazine-Arcjet.
