  2. Reusable launch vehicle - Wikipedia

    en.wikipedia.org/wiki/Reusable_launch_vehicle

    The historic Space Shuttle reused its Solid Rocket Boosters, its RS-25 engines and the Space Shuttle orbiter that acted as an orbital insertion stage, but it did not reuse the External Tank that fed the RS-25 engines. This is an example of a reusable launch system which reuses specific components of rockets.

  3. Jetex - Wikipedia

    en.wikipedia.org/wiki/Jetex

    The engine casing of the early motors is made of an aluminium alloy. On introduction, fuel pellets and wick could be purchased separately, meaning that the system is reusable. [2] Jetex power made a big impact in the late 1940s and early 1950s, allowing new sorts of models, scale and duration, to be designed.

  4. RD-0169 - Wikipedia

    en.wikipedia.org/wiki/RD-0169

    The RD-0162 rocket engine was developed at the Voronezh KBKhA after 2006, initially with an engine version aimed at 2,000 kN (200 tf) thrust, and later, after 2012, a smaller version with a thrust of 416 kN (42.4 tf) in the RD-0162SD version. Engine development funding was included in the Russian Federal Space Program for 2016–2025.

  5. Prometheus (rocket engine) - Wikipedia

    en.wikipedia.org/wiki/Prometheus_(rocket_engine)

    The Prometheus rocket engine is an ongoing European Space Agency (ESA) development effort begun in 2017 to create a reusable methane-fueled rocket engine for use on the Themis reusable rocket demonstrator and Ariane Next, the successor to Ariane 6, and possibly a version of Ariane 6 itself.

    en.wikipedia.org/wiki/Pratt_&_Whitney_XLR-129

    Cut-drawing of XLR-129 demonstrator engine. The XLR-129 was an American rocket engine design that would have used liquid hydrogen and liquid oxygen propellants. [1] It was developed by Pratt & Whitney and initially was to develop 250,000 lbf (1,100 kN) of thrust. It featured an expanding nozzle in order to tune performance over a wide range of ...

  7. Ammonium perchlorate composite propellant - Wikipedia

    en.wikipedia.org/wiki/Ammonium_perchlorate...

    Commercial APCP rocket engines usually come in the form of reloadable motor systems (RMS) and fully assembled single-use rocket motors. For RMS, the APCP "grains" (cylinders of propellant) are loaded into the reusable motor casing along with a sequence of insulator disks and o-rings and a (graphite or glass-filled phenolic resin) nozzle. The ...

  8. Model rocket - Wikipedia

    en.wikipedia.org/wiki/Model_rocket

    A model rocket is a small rocket designed to reach low altitudes (e.g., 100–500 m (330–1,640 ft) for a 30 g (1.1 oz) model) and be recovered by a variety of means. According to the United States National Association of Rocketry (NAR) 's Safety Code, [ 1 ] model rockets are constructed out of lightweight and non metallic parts.

  9. Retrorocket - Wikipedia

    en.wikipedia.org/wiki/Retrorocket

    A retrorocket (short for retrograde rocket) is a rocket engine providing thrust opposing the motion of a vehicle, thereby causing it to decelerate. They have mostly been used in spacecraft, with more limited use in short-runway aircraft landing. New uses are emerging since 2010 for retro-thrust rockets in reusable launch systems.
