Hall-Effect Thruster Engines, also known as Hall-effect thrusters or ion thrusters, use electric and magnetic fields to accelerate ions and produce thrust. The thrust force in a Hall-Effect Thruster can be described using the basic rocket thrust equation. Hall-Effect Thrusters are known for their efficiency and are commonly used in long-duration space missions.
The thrust equation for a turbojet engine using control volume analysis is expressed as:
where,
- is the thrust force,
- ṁe is the mass flow rate of exhaust gases in kilograms per second (kg/s).
- is the Exhaust velocity at the nozzle exit in meters per second (m/s).
- ṁ0 is the mass flow rate of inlet gases in kilograms per second (kg/s).
- is the Exhaust velocity at the nozzle Inlet in meters per second (m/s).
- is the Pressure at the nozzle exit in pascals (Pa).
- is the Pressure at the nozzle inlet in pascals (Pa).
- is the Area of the nozzle exit in square meters (m²).
