  2. Thruster - Wikipedia

    en.wikipedia.org/wiki/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. Reaction engine Spacecraft thrusters

  3. Colloid thruster - Wikipedia

    en.wikipedia.org/wiki/Colloid_thruster

    20 μN colloid thruster system. [1] A colloid thruster (or "electrospray thruster") is a type of low thrust electric propulsion rocket engine that uses electrostatic acceleration of charged liquid droplets for propulsion. In a colloid thruster, charged liquid droplets are produced by an electrospray process and then accelerated by a static ...

  4. Thrusters (spacecraft) - Wikipedia

    en.wikipedia.org/wiki/Thrusters_(spacecraft)

    A thruster is a spacecraft propulsion device used for orbital station-keeping, 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 propellant used in a rocket engine plays an important role in both engine design and in design of the launch vehicle and related ground equipment to service the vehicle. Weight, energy density , cost, toxicity, risk of explosions, and other problems make it important for engineers to design rockets with appropriate propellants.

  6. Reaction engine - Wikipedia

    en.wikipedia.org/wiki/Reaction_engine

    A reaction engine is an engine or motor that produces thrust by expelling reaction mass (reaction propulsion), [1] in accordance with Newton's third law of motion.This law of motion is commonly paraphrased as: "For every action force there is an equal, but opposite, reaction force."

    The best performance (in terms of thrust efficiency and power-to-thrust ratio) can be obtained using high atomic weight alkali metals, such as cesium (Cs, 133 amu) and rubidium (Rb, 85.5 amu). These propellants have a low ionization potential (3.87 eV for Cs and 4.16 eV for Rb), low melting point (28.7 °C for Cs and 38.9 °C for Rb) and very ...
