The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
'Rocket Engine 0120', GRAU index: 11D122) was the Energia core rocket engine, fueled by LH 2 /LOX, roughly equivalent to the Space Shuttle Main Engine (SSME). These were attached to the Energia core rather than the orbiter, so were not recoverable after a flight, but created a more modular design (the Energia core could be used for a variety of ...
Ullage engine on the side of Saturn V third stage Three sets of ullage motors are shown in this schematic of the Saturn V rocket. The Agena-A was one of the first vehicles to make use of an ullage system in preparation for ignition after separating from its Thor booster. [2]
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.
Archimedes is presented as a highly reusable liquid-propellant engine using methane and liquid oxygen in an oxidizer-rich staged combustion cycle. [1] [2] There are both sea-level and vacuum variants. The engine is mostly 3D printed, [7] with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas ...
The engine was conceived in 2014, and received US government funding to build a prototype engine in 2016. [2] By 2018, the USAF had committed US$295 million of government funding to develop the engine and build an initial engine prototype, while Aerojet will put US$86 million of private capital into the project through the prototype build.

RocketMotorTwo (RM2) [1] is a family of hybrid rocket engines developed for the Scaled Composites SpaceShipTwo suborbital spaceplane. The first-generation engine was developed by Sierra Nevada Corporation (SNC), [2] from the late 2000s to May 2014. It was first ignited in flight during a SpaceShipTwo test launch in April 2013.
PSLV-C50 second stage with Vikas engine. The engine uses up about 40 metric tons of UDMH as fuel and Nitrogen tetroxide (N 2 O 4) as oxidizer with a maximum thrust of 725 kN. An upgraded version of the engine has a chamber pressure of 58.5 bar as compared to 52.5 bar in the older version and produces a thrust of 800 kN.
