Thruster may refer to: Propulsion devices 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. Reaction engine 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 Plasma thruster 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 hydraulic motor and propeller combined in single unit to propel the ROV, AUV or UUV Transportation Thruster (surfing) is a surfboard fin design Shkadov thruster, hypothetical megascale reaction for moving a star Vehicles Avio Delta Thruster, a Bulgarian ultralight trike design Thruster T600 Sprint, a British ultralight aircraft Others Hurrying, also called 'coal thrusting', a 19th-century profession Big Mother Thruster, hard rock band Thruster (crossfit), a combination of a front squat and a push press See also Thrust (disambiguation)
