Liquid rocket engines have tankage and pipes to store and transfer propellant, an injector system and one or more combustion chambers with associated nozzles.. Typical liquid propellants have densities roughly similar to water, approximately 0.7 to 1.4 g/cm 3 (0.025 to 0.051 lb/cu in).
The Curie engine, named after Polish scientist Marie Skłodowska–Curie, is a small liquid-propellant rocket engine designed to release "small satellites from the constricting parameters of primary payload orbits and enables them to fully reach their potential, including faster deployment of small satellite constellations and better positioning for Earth imaging".

Since one or more of the propellants is in the liquid phase, all cryogenic rocket engines are by definition liquid-propellant rocket engines. [2] Various cryogenic fuel-oxidizer combinations have been tried, but the combination of liquid hydrogen fuel and the liquid oxygen oxidizer is one of the most widely used.
The Rocketdyne division of North American Aviation developed a relatively small liquid-fuelled rocket engine for thrust augmentation of manned aircraft during the late 1950s. The AR2 is a single-chamber rocket engine burning kerosene ( JP-4 or JP-5 ) jet fuel, oxidised with 90% High Test Peroxide (H 2 O 2 / HTP), allowing the engine to use the ...
It is a small liquid-propellant rocket engine designed to be simple and cheap to produce. It is used as both a first-stage and a second-stage engine, which simplifies logistics and improves economies of scale. [5] [6] To reduce its cost, it uses the electric-pump feed cycle, being the first flight-ready engine of such type. [4]
An LR105 Atlas sustainer engine on display at the Air Zoo.. The LR105 is a liquid-fuel rocket engine that served as the sustainer engine for the Atlas rocket family. [1] [2] [3] Developed by Rocketdyne in 1957 as the S-4, [4] [5] [6] it is called a sustainer engine because it continues firing after the LR89 booster engines have been jettisoned, providing thrust during the ascent phase.
The LE-5 liquid rocket engine and its derivative models were developed in Japan to meet the need for an upper stage propulsion system for the H-I and H-II series of launch vehicles. It is a bipropellant design, using LH 2 and LOX. Primary design and production work was carried out by Mitsubishi Heavy Industries. [1]
