How can a rocket burn its fuel in space?
Rockets carry their own oxidizer to burn their fuel in space, as there is no oxygen available in space for combustion. The fuel and oxidizer react together in the rocket engine to produce thrust, allowing the rocket to move forward. This allows rockets to function in the vacuum of space where there is no atmospheric oxygen.
What needs To burn fuel in rocket?
You need a fuel. You need something that will react or "burn" with it. This is called an oxidizer, even though oxygen is not always what is used. You need a means of forcing the fuel into a combustion chamber. You need a combustion chamber. And you need an exhaust bell for the spent fuel to leave! Some rockets need an igniter, something to set the fuel and oxidizer off. Other rockets use "hypergolic" fuels, which means that the fuel and oxidizer go off just by coming into contact. This is good because not having an igniter means one less thing that can go wrong. The lunar module had this kind of engine. Solid rockets have the fuel and oxidizer mixed together, just waiting to be ignited. The burning fuel hollows the rocket out, forming a sort of combustion chamber.
What gas is in a rocket?
Most rockets use liquid oxygen (LOX) as an oxidizer to burn fuel, such as liquid hydrogen or kerosene. This combination creates a chemical reaction that produces thrust to propel the rocket.
What is the role of an oxidizer in a solid fuel system?
A solid rocket engine uses a fuel and an oxidizer. The oxidizer when burned delivers oxygen to the fuel so that it can burn. Most rockets use oxidizers because when the rocket burns it uses so much oxygen that they need a readily available supply.
What is burn time in solid rocket motor?
It depends on the motor. The Space Shuttle's 4-segment motor burns for 124 seconds, for instance. The Atlas V's solid rocket motors burn for 90 seconds. A common size B4 model rocket motor burns for 1 second. it depends on the size of the rocket, the grain material, and the oxidizer to tell you how long one will burn.

What is the difference between a jet engine and a rocket engine in relations to oxygen?
A jet engine takes oxygen from the air to burn with its fuel. A rocket engine has to take oxygen or some comparable oxidizer with it.
How does rocket fuel burn without air?
That's a very important question. To be very technical, the rocket motor burns without "air" ... outside the atmosphere ... because it takes its own oxygen along with it. There's always a chemical called an "oxidizer" somewhere in the rocket, either mixed into the fuel, or else in a separate tank.

What is the difference between how a rocket achieves flight and how an aeroplane does?
assuming you mean a jet plane, the only difference is that the plane gets oxidizer from the atmosphere around it, while the rocket brings its own.both jets and rockets work by igniting fuel mixed with oxidizer. an oxidizer is something containing oxygen, so that the fuel can burn, since nothing can burn without oxygen.in a jet, this is often kerosene mixed with air. in a rocket, this is often liquid hydrogen mixed with liqiud oxygen.the jet gets air from outside through air intakes, while the rocket gets the liquid oxygen from a tank it brings along.

What do rockets need to burn fuel?
Rockets need a fuel source, such as liquid hydrogen or kerosene, and an oxidizer, such as liquid oxygen, to burn the fuel. The combination of fuel and oxidizer creates a chemical reaction that produces thrust, propelling the rocket forward. Additionally, rockets require an ignition source, such as a spark or heat, to initiate the combustion process.
What is a rocket igniter?
A rocket igniter is a device used to spark a controlled ignition of rocket engines. It typically uses a pyrotechnic material to generate a flame or hot gas that starts the combustion process in the rocket engine. The igniter is an essential component for launching rockets and initiating controlled propulsion.
Does a rocket motor burn fuel without air?
Yes, rocket motors can burn fuel without the presence of air because they carry their own oxidizer, which provides the oxygen needed for combustion. This allows them to operate in the vacuum of space where there is no air.
What does a rocket need to take off?
A rocket needs a powerful thrust to overcome Earth's gravity and lift off. This thrust is typically provided by rocket engines that burn fuel to create a force that propels the rocket upward. Additionally, the rocket needs a stable structure to withstand the forces of liftoff and the harsh conditions of space.
