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.
'Rocket Engine 0255') is a propulsion module composed of an RD-0256 main engine and a RD-0257 Vernier thruster. Both are liquid-fuel rocket engines, burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide ( N 2 O 4 ) oxidizer.

The RS-68 (Rocket System-68) was a liquid-fuel rocket engine that used liquid hydrogen (LH 2) and liquid oxygen (LOX) as propellants in a gas-generator cycle. It was the largest hydrogen-fueled rocket engine ever flown. [3] Designed and manufactured in the United States by Rocketdyne (later Pratt & Whitney Rocketdyne and Aerojet Rocketdyne).
The RD-864 (Russian: Ракетный Двигатель-864, romanized: Raketnyy Dvigatel-864, lit. 'Rocket Engine 864', GRAU index: 15D177) is a Soviet liquid-fuel rocket engine burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide (N 2 O 4) oxidizer in a gas generator combustion cycle.

The same day, the Neutron page on Rocket Lab's website was updated specifying the thrust of the nine Archimedes engines used on the first stage as 5,960 kN (1,340,000 lbf) at sea level and a maximum thrust of 7,530 kN (1,690,000 lbf) and the upper stage's single vacuum optimized Archimedes at 1,110 kN (250,000 lbf).
The gas-generator cycle, also called open cycle, is one of the most commonly used power cycles in bipropellant liquid rocket engines. Propellant is burned in a gas generator (or "preburner") and the resulting hot gas is used to power the propellant pumps before being exhausted overboard and lost.
