Thrusters (spacecraft)
A thruster is a
attitude control, or long-duration, low-thrust acceleration, often as part of a reaction control system. A vernier thruster or gimbaled engine are particular cases used on launch vehicles where a secondary rocket engine or other high thrust device is used to control the attitude of the rocket, while the primary thrust engine (generally also a rocket engine) is fixed to the rocket and supplies the principal amount of thrust.[1][2][3][4][5]
Some devices that are used or proposed for use as thrusters are:
- Cold gas thruster
- Electrohydrodynamic thruster, using ionized air (only for use in an atmosphere)
- Electrodeless plasma thruster, electric propulsion using ponderomotive force
- Electrostatic ion thruster, using high-voltage electrodes
- Hall effect thruster, a type of ion thruster
- Ion thruster, using beams of ions accelerated electrically
- Magnetoplasmadynamic thruster, electric propulsion using the Lorentz force
- Pulsed inductive thruster, a pulsed form of ion thruster
- Pulsed plasma thruster, using current arced across a solid propellant
- RF resonant cavity thruster, an electromagnetic thruster using microwaves
