  2. 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 ...

  3. SpaceX Draco - Wikipedia

    en.wikipedia.org/wiki/SpaceX_Draco

    On February 1, 2012 SpaceX announced that it had completed the development of a new, more powerful storable-propellant rocket engine, this one called SuperDraco. This high-thrust hypergolic engine—about 200 times larger than the Draco RCS thruster hypergolic engine—offers deep throttling ability and just like the Draco thruster, has multiple restart capability and uses the same shared ...

    en.wikipedia.org/wiki/Reaction_control_system

    Two of four Reaction Control System thruster quads on the Apollo Lunar Module. A reaction control system (RCS) is a spacecraft system that uses thrusters to provide attitude control and translation. Alternatively, reaction wheels can be used for attitude control.

    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

  6. Ion thruster - Wikipedia

    en.wikipedia.org/wiki/Ion_thruster

    An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms. The ions are then accelerated using electricity to create thrust.

  7. Cold gas thruster - Wikipedia

    en.wikipedia.org/wiki/Cold_gas_thruster

    A cold gas thruster (or a cold gas propulsion system) is a type of rocket engine which uses the expansion of a (typically inert) pressurized gas to generate thrust.As opposed to traditional rocket engines, a cold gas thruster does not house any combustion and therefore has lower thrust and efficiency compared to conventional monopropellant and bipropellant rocket engines.

  8. 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."

  9. SpaceX Merlin - Wikipedia

    en.wikipedia.org/wiki/SpaceX_Merlin

    In 2011, performance goals for the engine were a vacuum thrust of 690 kN (155,000 lbf), a vacuum specific impulse (I sp) of 310 s (3.0 km/s), an expansion ratio of 16 (as opposed to the previous 14.5 of the Merlin 1C) and chamber pressure in the "sweet spot" of 9.7 MPa (1,410 psi). Merlin 1D was originally designed to throttle between 100% and ...
