Which substance is a liquid fuel used in rocket engine?
Traditionally, rockets use cryogenic (super-cold) oxygen and hydrogen.
What is a cryogenic engine?
AnswerCryogenic Engines are rocket motors designed for liquid fuels that have to be held at very low "cryogenic" temperatures to be liquid - they would otherwise be gas at normal temperatures. Typically Hydrogen and Oxygen are used which need to be held below 20°K (-423°F) and 90°K (-297°F) to remain liquid. The engine components are also cooled so the fuel doesn't boil to a gas in the lines that feed the engine. The thrust comes from the rapid expansion from liquid to gas with the gas emerging from the motor at very high speed. The energy needed to heat the fuels comes from burning them, once they are gasses. Cryogenic engines are the highest performing rocket motors. One disadvantage is that the fuel tanks tend to be bulky and require heavy insulation to store the propellant. Their high fuel efficiency, however, outweighs this disadvantage.The Space Shuttle's main engines used for liftoff are cryogenic engines. The Shuttle's smaller thrusters for orbital manuvering use non-cyogenic hypergolic fuels, which are compact and are stored at warm temperatures. Currently, only the United States, Russia, China, France, Japan and India have mastered cryogenic rocket technology.
Is xenon used in cryogenic chambers?
Not especially.
What is another name for a compression ignition engine?
many would simply call it a diesel engine, in reference to the most commonly used fuel for them.
Where cryogenic valves are used?
Cryogenic valves facilitate the transfer of Liquified gas. Space industry, natural gas / petroleum, medical industry, chemicals.
What is the equivalent of the fuel to go to the moon?
Many different fuels can be used on such a trip. Especially for different purposes and phases of the flight. For example on the Apollo missions to the moon, the Saturn V rocket used kerosene as fuel on the first stage and cryogenic liquid hydrogen on the upper 2 stages, the service module used monomethylhydrazine as fuel, the lunar module used aerozine 50 as fuel for both descent and assent stages.
What is the purpose of the fuel system?
he purpose of the fuel system is to supply the right amount of fuel for the engine to burn, and control the speed of the engine.
What is fuel stablizer?
Fuel stabilizer protects the engine from decay when it isn't being used.
How does cryogenic engine work?
The cryogenic engine gets its name from the extremely cold temperature at which liquid nitrogen is stored. Air moving around the vehicle is used to heat liquid nitrogen to a boil. Once it boils, it turns to gas in the same way that heated water forms steam in a steam engine. A rocket like the Ariane 5 uses oxygen and hydrogen, both stored as a cryogenic liquid, to produce its power. The liquid nitrogen, stored at -320 degrees Fahrenheit, is vaporized by the heat exchanger. Nitrogen gas formed in the heat exchanger expands to about 700 times the volume of its liquid form. This highly pressurised gas is then fed to the expander, where the force of the nitrogen gas is converted into mechanical power.
What is cryogenic freezer?
A cryogenic freezer is used to bring components inside the freezer down to cryogenic temperatures. Many cryogenic freezers are available for all sorts of applications. Cold boxes with added ln2 capabilities can refrigerate parts and then complete cryogenic processing cycles. Additionally, cryo freezers are available to freeze sex cells, stems cells, and more. Sometimes people are frozen after death, which is called cryonics. I have added a site below that has cryogenic freezers and processors available.
Name of fuel used in Aeroplanes?
turbine fuel or aviation fuel
Types of engine according to fuel used?
all engine using gasoline (whether regular or premium) as fuel is called gasoline engine. motorcycle engine. generetors, buses. are example of gasoline engine
