Why is liquid oxygen used in space shuttle engines?
Liquid Nitrogen is used in a Space Shuttle to cool down the Space Shuttle Main Engine's (SSME) Main Combustion Chamber (MCC) because the temperatures experienced during lift exceed 3,315 degrees Celcius or 6,000 degrees Fahrenheit. If Liquid Nitrogen was not used the SSME would warp in shape and melt.
Why NAD plus can be used to shuttle electrons?
NAD+ can shuttle electrons because it can accept electrons to become reduced to NADH, which can then donate those electrons to other molecules in the cell. This ability to cycle between oxidized (NAD+) and reduced (NADH) forms allows NAD+ to act as a carrier of high-energy electrons during processes like cellular respiration.
How are sensors used to detect toxic chemicals in the space shuttle would be beneficial to a factory worke?
Sensors in the space shuttle can be repurposed for a factory worker by providing real-time detection of toxic chemicals in their work environment, enabling them to take immediate action to mitigate risks. This technology can help prevent exposure to harmful substances, safeguarding the health and well-being of the worker and ensuring a safer work environment.
What is the gas coming from the bottom of a rocket before launch?
What we see, at least in the instance of the space shuttle launch, is hydrogen and oxygen being vented. About the last thing we do before sending the shuttle up is fuel it. Liquid hydrogen and liquid oxygen are pumped into the cryogenic tank (the giant cylindrical container to which the shuttle itself is connected, and to which the solid booster rockets are attached. As the liquid hydrogen and oxygen are pumped in, they supercool the tanks in which they enter. As the tanks cool, some of the hydrogen and some of the oxygen are "boiled off" in that cooling process. The H2 and O2 have changed phase to a gas, but are still extremely cold, and as the liquid H2 and O2 full the tanks, that very cold gas is vented off and, because it is so cold, it appears as the "clouds" or "steam-looking" stuff that is visible during (and up to) launch.
Why are fuel cells used on the space shuttle instead of batteries?
Two reasons:Weight. Batteries are heavier per energy unit than fuel cells.Capacity. Fuel cells can store much more energy than batteries.As a bonus, the weight for the fuel cell fuel reduces the weight of another required consumable: water. The "exhaust" of fuel cells is pure water which astronauts can drink.
What does hypergolic mean when talking about rockets?
Hypergolic refers to the proplusion system. Hypergolic propellants react when mixed together. They don't need an ignition system, and the fuel and oxidizer are often not cryogenic which makes them easier to store. They also tend to be more reliable with less points of failure and simpler design. Some examples: Monomethylhydrazine (fuel) + Nitrogen Tetroxide (oxidizer) -- used in the US Space Shuttle OMS and RCS system. Unsymmetrical Dimethylhydrazine (fuel) + nitrogen tetroxide (oxidizer) -- used in Soviet and French rockets. Aerozine 50 (fuel, it's a blend of UDMH+MMH) + nitrogen tetroxide (oxidizer) -- used in various Apollo rocket components.
What is nitrogen shuttle?
a molecule that carries Nitrogen and can Donate the Nitrogen towards building of other molecules like proteins or DNA. An important Nitrogen Shuttle is Glutamine. It can produce Ammonium, be a source of energy and have other functions too.
How much fuel is burned on shuttle lift off?
Each of the two SRB (Solid Rocket Boosters) contains more than 1 million pounds of solid propellant. The large External Tank, to which the Shuttle is attached, contains more than 500,000 gallons of super-cold liquid oxygen and liquid hydrogen which are mixed and burned together to form the fuel for the Shuttle's three main rocket engines. The Shuttle proper with its Orbital Maneuvering System (OMS) has two engines (one on either side of the tail) that burn monomethyl hydrazine fuel (CH3NHNH2) and nitrogen tetroxide oxidizer (N2O4) which ignites automatically (no spark required) in the absence of oxygen in space.
What fuel does the space shuttle use?
The space shuttle uses liquid hydrogen as the main engine fuel, along with liquid oxygen as an oxidizer. The shuttle uses two solid-fuel boosters (SRBs) that contain a mixture that is mostly aluminum powder, iron oxide, and ammonium perchlorate (the oxidizer, which is about 70% of the chemical mix).While in orbit, the space shuttle uses hydrazine (N2H4) and nitrogen tetroxide (N2O4) for thrust, as these chemicals are relatively stable for a long duration in space and provide excellent thrust to weight ratio. However, these chemicals are very poisonous, and after the shuttle lands the crew remains inside for several minutes to allow any remaining reaction gases to dissipate.
What kind of engine does the space shuttle have?
The Space Shuttle Main Engines (SSMEs) also known as the RS-24 engines are liquid fueled reusable engines made by Rocketdyne and burn liquid hydrogen as their fuel and liquid oxygen as the oxidiser. The shuttle has three engines. The fuel is stored in the large orange External Tank strapped to the shuttle's belly. On the way to orbit, the shuttle also uses two reusable solid rocket boosters (SRBs) which provide about 83% of the takeoff thrust. These use a solid fuel containing aluminum (the fuel), ammonium perchlorate (the oxidiser), iron oxide (a catalyst), and the mixture is held together with an epoxy and a binder (which also acts as fuel). While in space, the shuttle uses the reaction control system (RCS) thrusters which are seen on various places on the shuttle orbiter, and two orbital manoeuvering system (OMS) engines. The RCS and OMS use monomethyl hydrazine as the fuel and nitrogen tetroxide as the oxidiser.
Which fuel use in rocket?
There are two three types of fuel used in rockets 1) Solid fuel - an aluminum powder used for an initial boost into space. 2) Liquid fuel - usually super-cold liquid hydrogen and oxygen is used is the Space Shuttle's main engines during launch. 3) Hypergolic fuel - Monomethylhydrazine and Nitrogen Tetroxide does not need a source of ignition. It is mainly used for maneuvering in space.
What kind of fuel does the space shuttle use?
The space shuttle used a mixture of liquid hydrogen and liquid oxygen as fuel for its main engines. These propellants are combustion products of a chemical reaction that produces high thrust for the shuttle's liftoff and orbital maneuvers.
How does the space shuttle carry enough fuel for a mission?
The space shuttle uses liquid nitrogen and liquid oxygen as fuel. Generally a sufficient quantity of fuel is carried but if need be re-fuelling can be done in space.
What is the orbital maneuvering system engine?
The OMS engines on the shuttle (there are two) are two hypergolic propellant powered engines used by the shuttle during ascent, orbit and deorbit. During launch, the engines MAY be used after main engine cutoff to boost the Shuttle to a predetermined elliptical orbit. This is called OMS-1 burn. OMS-1 may not be required based on the payload and mission. OMS-2 burn is used to circularize the elliptical orbit that the shuttle first enters after launch. The engines may be used to change the shuttle's orbital characteristics during its mission. The engines are used to deorbit the Shuttle so that it may reenter the atmosphere to come back home.
Why is liquid oxygen used in space shuttle engines?
Liquid Nitrogen is used in a Space Shuttle to cool down the Space Shuttle Main Engine's (SSME) Main Combustion Chamber (MCC) because the temperatures experienced during lift exceed 3,315 degrees Celcius or 6,000 degrees Fahrenheit. If Liquid Nitrogen was not used the SSME would warp in shape and melt.
What is the fuel used in space shuttles?
Liquid Oxygen and liquid hydrogen in the fuel tank. The orbiter uses Monomethylhydrazine (MMH) and Nitrogen tetroxide or peroxide(N2o4).For takeoff the shuttle uses a hydrogen/ oxygen mixture. In orbit it uses a solid mixture of powdered aluminum and ammonium perchlorateAll current spacecraft use chemical rockets (bipropellant or solid-fuel) for launchLiquid O2
