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. Because of this loss, this type of engine is ...
This category is for those rocket engines using the pure gas generator cycle, like the Rocketdyne F-1, or the steam generator cycle, like the RD-107. Pages in category "Rocket engines using the gas-generator cycle"
The Russian RD-180 engine also employs a staged-combustion rocket engine cycle. Lockheed Martin began purchasing the RD-180 in circa 2000 for the Atlas III and later, the V , rockets. The purchase contract was subsequently taken over by United Launch Alliance (ULA—the Boeing/Lockheed-Martin joint venture) after 2006, and ULA continues to fly ...
The engine uses a gas-generator cycle developed in the United States in the late 1950s and was used in the Saturn V rocket in the 1960s and early 1970s. Five F-1 engines were used in the S-IC first stage of each Saturn V, which served as the main launch vehicle of the Apollo program .
The RD-119 (GRAU Index 8D710) was a liquid rocket engine, burning liquid oxygen and UDMH in the gas-generator cycle. [3] It has a huge expansion ratio on the nozzle and uses a unique propellant combination to achieve an extremely high isp of 352 s for a semi-cryogenic gas-generator engine. It also has a unique steering mechanism.
The RD-214 (GRAU Index 8D59) was a liquid rocket engine, burning AK-27I (a mixture of 73% nitric acid and 27% N 2 O 4 + iodine passivant and TM-185 (a kerosene and gasoline mix) in the gas generator cycle. [2] [3] As was the case with many V-2 influenced engines, the single turbine was driven by steam generated by catalytic decomposition of ...
The term often refers to a device that uses a rocket propellant to generate large quantities of gas. The gas is typically used to drive a turbine rather than to provide thrust as in a rocket engine. Gas generators of this type are used to power turbopumps in rocket engines, in a gas-generator cycle. It is also used by some auxiliary power units ...
Fastrac was a turbo pump-fed, liquid rocket engine. The engine was designed by NASA as part of the low cost X-34 Reusable Launch Vehicle (RLV) [4] and as part of the Low Cost Booster Technology (LCBT, aka Bantam) project. [5] This engine was later known as the MC-1 engine when it was merged into the X-34 project.
