What is the reason for having a combustion chamber on a rocket?

A combustion chamber is where combustion occurs in a controlled fashion. Because the basic idea of a rocket is burning fuels and directing them in the opposite direction to that of travel, a controlled burning - as happens in the combustion chamber - is exactly what a rocket needs to work.

What did Harrison Allen Jr invent?
Harrison Allen Jr. specialized in the development of high energy fuels for rockets, super sonic combustion and solid rocket propellant rocket motors.
Would rockets work in a vacuum?
Yes they do. The rockets fuel, either solid, compressed gas would expand on release thru the 'exhaust' of the rocket/fuel container, and cause the rocket to move in the opposite direction. Example: Geo-stationary satellites have small rockets to keep them in place, and prevent or correct drifting, so that they can stay locked into their earth relay stations. Minute bursts of firing of these rockets on the satellites is done at an altitude of almost 36000Km above the surface of the earth, in what is near vacuum.
What is the definition of a rocket body tube?
A rocket body tube is the center of a rocket; also the piece that holds the rocket together.
How could a toy rocket accelerate after takeoff?
As long as the thrust is more than the weight of the rocket (toy or otherwise) the rocket will accelerate. When the thrust matches the weight, the rocket will cruise. When the thrust is less then the rocket will slow.
Does the thrust of a rocket need to be created by an explosion?
no, the thrust of a rocket relies on the trajectory of the rockets tilt and overall slanted angle. The rocket is sent via a useful queef, that blasts the rocket from the platform
What is the combustion chamber of a rocket?
Florence
What happens when gas molecules hit the inside of a rocket's combustion chamber?
The rocket pushes back on the gas.
What happens when gas molecules hit inside of the rocket's combustion chamber?
The rocket pushes back on the gas.
Where do the rocket exerts force in pressure?
Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.
Is rocket engines are internal combustion engines?
YES the oxidizer and propelant are mixed into a chamber the ignited.
How does a rocket worke?
The critical part of a liquid-fueld rocket that provides it with its ability to "fly" is the combustion chamber, sometimes, but not always, including a shaped nozzle, positioned at the rear (bottom) end of the vehicle. The combustion chamber is open at one end. In its simplest form the chamber is bowl-shaped (a half-sphere) with its open end pointing down, away from the vehicle. The Saturn V, used for the Apollo missions, used this kind of combustion chamber. Combustible liquids are pumped into the chamber. This may consist of a single, essentially self-igniting, liquid, or it may consist of two or more liquids which, when combined, can be made to combust. The Saturvn V used kerosene (the fuel) and liquid oxygen (the oxidizer). When the engine is "lit" so that the fuel is burning (more like "exploding") inside the combustion chamber it creates tremendous pressures inside the chamber. Some of that pressure is against the upper, inside portion of the combustion chamber, and it is that pressure (force) against the upper inner surface of chamber that propells the rocket. Since the chamber is open at one end the forces in that direction cause the combustion exhaust gases to exit the chamber. This causes an "exhaust plume" out of the back of the rocket engine. Some have described this as being a situation where the exhaust plume "pushes" the rocket, or that it is the exhaust plume that causes the rocket to move, or that the rocket "rides on top of a trail of fire". But that is not the case and is not a correct way of describing what happens. The exhaust plume does NOT move the rocket. The exhaust plume does NOT cause the rocket to move. Rather, the combustion pressures inside the combustion chamber causes both the rocket motion AND the exhaust motion. Some have also noted that, since Sir Isaac Newton's Third Law Of Motion states that " For every action, there is an equal and opposite reaction ", it is therefore the rapidly exiting gases from the rear of the rocket that cause the rocket to move forward. Again, this is not a correct description of the situation. Yes, the Third Law of Motion applies to the rocket. Yes, there is both a forward motion of the rocket and a backward motion of the exhaust gases. But it is not correct to say that the one (exhaust gasses) CAUSES the other (the rocket motion). Yes, there is a mathematical, physical relationship between the motion of the exhaust and the motion of the rocket (taking in to account their respective masses), and given a measurement of one you can calculate the other (e.g. knowing the velocity and mass of the exhaust gasses and the mass of the rocket you can calculate the velocity of the rocket). But it is NOT valid to say that the rocket motion is CAUSED BY the exhaust gas' motion. The correct view on this is that both the motion of the exaust gas and the motion of the rocket are caused by the combustion pressure inside the combustion chamber.

If the name Rocket Lorena stove derives from the operation principle of this stove how is it that the operation of the stove compares to that of a rocket?
The Rocket Lorena stove derives its name from the addition of elements of the Rocket Stove into the Lorena Stove. Lorena is from a combination of the Spanish words for 'clay' and 'sand', which are mixed to make the mortar used in its construction. I am guessing here that the Rocket Stove may have gotten its name from its use of an L-shaped combustion chamber called the "rocket elbow," which rockets the combustion upwards. It thereby allows full combustion of the fuel at the front of the stove while localizing the burn to just the ends of the sticks inside the combustion chamber, which is at the crook of the elbow, thereby conserving wood. The Rocket Lorena has added this "rocket-elbow" combustion chamber to the Lorena stove. It has also added better insulation materials, such as pumice, clay-sawdust or clay-husk mortar, or whatever else is locally available, around the firebox and the rest of the heat passageway. Additional thought: Regarding why the Rocket Stove is called a rocket, it might also be because the rocket stove looks somewhat like a rocket. Or else because the stove's combustion chamber bears some analogy with the combustion chamber found in liquid-fueled rockets. Though the Wikipedia listing for rocket stove does not answer this mystery, it does give links to sources that may be able to do so, such as the Aprovecho Research Center. Apparently, the 'rocket' half of the name of this energy efficient stove is derived also from the swooshing sound the stove makes as the heat trys to escape from the top of stove.
How do rockerts work?
At the center of every rocket is a device called the combustion chamber. Here rocket fuel is mixed and ignited into a controlled explosion. The explosion produces a pressure on the walls of the chamber. There is only one (external) opening to the chamber which opens to the rear of the rocket. Through this opening the exploded products escape, because of this there is no force exerted by the wall of the chamber against the explosion. This means that there is an unopposed force on the opposite end of the chamber - the force that moves the rocket 'forwards'.
Where are hot gases with a lot of pressure on a rocket held?
They are generated in the combustion chamber. Then they exit the rocket through the nozzle. The gas is never actually "held" in the sense of a storage tank.
How does the liquid fuel rocket work?
by burning liquid fuel with a liquid oxidizer in a combustion chamber connected to the exhaust nozzle. this generates thrust.
What is the danger for a rocket having a air pocket inside the solid fuel?
The rocket might explode from the added pressure when the combustion reaction hits the air pocket. - apex
