Thruster

A thruster is a propulsive device used by spacecraft and watercraft for station keeping, attitude control, in the reaction control system, or long-duration, low-thrust acceleration.

Spacecraft thrusters

• Rocket engine, using exothermic chemical reactions of the propellant(s)
• Electrohydrodynamic thruster, using ionized air (only for use in an atmosphere)
• Electrostatic ion thruster, using high-voltage electrodes
• Ion thruster, using beams of ions accelerated electrically
• Hall effect thruster, a type of ion thruster
• Pulsed inductive thruster, a pulsed form of ion thruster
• Magnetoplasmadynamic thruster, electric propulsion using the Lorentz force
• Electrodeless plasma thruster, electric propulsion using ponderomotive force
• Pulsed plasma thruster, using current arced across a solid propellant

Marine thrusters

• Azimuth thruster, pod underneath a ship, instead of a propeller and rudder
• Bow thruster, or stern thruster, at the bow or the stern of a ship or boat
• Rim-driven thruster, electric motor and propeller combined in single unit

• Underwater Thrusters, electric motor or hydrolic motor and propeller combined in single unit to propel the ROV, AUV or UUV
