Cryogenic fuel - Wikipedia
网页Cryogenic fuels are fuels that require storage at extremely low temperatures in order to maintain them in a liquid state. These fuels are used in machinery that operates in space (e.g. rockets and satellites) where ordinary fuel cannot be used, due to the very low temperatures often encountered in space, and the absence of an environment that ...
Cryogenics - Wikipedia
网页Another use of cryogenics is cryogenic fuels for rockets with liquid hydrogen as the most widely used example. Liquid oxygen (LOX) is even more widely used but as an oxidizer, not a fuel. NASA's workhorse Space Shuttle used cryogenic hydrogen/oxygen propellant as its primary means of getting into orbit.
Cryogenic propellant management in space: open challenges and ...
网页2024年3月20日 — Cryogenic fuels (propellants, i.e., hydrogen, methane, and oxidizer, i.e., oxygen) have several advantages: they provide a high specific impulse, are non-toxic, and can be produced in situ (In...
Brr, It’s Cold in Here! NASA’s Cryo Efforts Beyond the Atmosphere
网页2024年1月11日 — One of those challenges is working with cryogenic fluids, meaning fluids existing in a liquid state between minus 238 degrees Fahrenheit and absolute zero (minus 460 F). These fluids – liquid hydrogen (the most difficult to work with), methane, and oxygen – are vital to spacecraft propulsion and life support systems.
Understanding Cryogenic Fuels: Revolutionizing Space and Beyond
网页2024年1月22日 — Cryogenic fuels represent a critical component in modern aerospace and energy sectors. These substances, which exist as gases at standard temperature and pressure, are cooled to cryogenic temperatures (below -150°C or …
Cryogenic fuels in aviation - Aerospace America
网页Cryogenic fuels like hydrogen and natural gas are possible solutions, a crucial consideration for these fuels is their high volumetric and gravimetric energy densities. Liquification is required to maximize the volumetric energy density. Cryogenic technology is also advancing its energy efficiency.
Cryogenic rocket engine - Wikipedia
网页Cryogenic rocket engine. A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel and oxidizer; that is, both its fuel and oxidizer are gases which have been liquefied and are stored at very low temperatures. [1] These highly efficient engines were first flown on the US Atlas-Centaur and were one of the main factors of NASA 's ...
NASA Tests Game Changing Composite Cryogenic Fuel Tank
网页2013年7月2日 — Cryogenic propellants are gasses chilled to subfreezing temperatures and condensed to form highly combustible liquids, providing high-energy propulsion solutions critical to future, long-term human exploration missions beyond low-Earth orbit.
Zero-Boil-Off Tank Experiments to Enable Long-Duration Space ...
网页2024年3月12日 — Cryogenic fluid management and use of hydrogen as a fuel are not limited to space applications. Clean green energy provided by hydrogen may one day fuel airplanes, ships, and trucks on Earth, yielding enormous climate and economic benefits.
网页It is obvious which segments of the global civil aviation fleet use most of fuel (and produce the most climate impact) So it helps to focus our efforts on certain vehicle classes. Single aisle and twin aisle aircraft are also highly sensitive to fuel energy density and volume. These aircraft designs have become highly optimized around Jet-A fuel.
