What is the function of a rocket nozzle?
The function of a rocket nozzle is to allow the thrust to be focuses and amplified. It also prolongs the burn time and greatly increases performance.
How does rocket fuel burn in space without oxygen?
The rocket carries its own supply of oxygen with which to burn the fuel.
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.
How long does a model rocket motor last?
Provided they are kept in a dry, cool, and stable environment, they should last indefinitely. The ingredients are non-volatile, so they do not really degrade over time. If you want to know how long they burn for, you need to look at the rating on the side of the rocket. A higher thrust number means that it will burn for a shorter amount of time. Most small model rocket engines burn for 3 to 5 seconds.
What is a rocket igniter?
A device that ignites the fuel & oxidizer mixture in the rocket engine when a "burn" is to begin.it lights the rocket.
A rocket is a motor that can burn fuel without requiring?
air
What do you mean by effective jet velocity of a rocket?
Effective jet velocity of a rocket is the increased velocity of a rocket in a short span of time. It is achieved with the use of either solid or liquid propellants.Ê
Why does rocket fuel burn in space?
oxygen is added from a separate tank
How does the size affect the flight of a rocket?
A small rocket might go higher because a smaller rocket has less weight
How do you make rocket launch faster?
You only have a few choices: -- reduce the total weight (mass) of the rocket and its payload -- burn fuel faster -- burn fuel at the same rate but use fuel with a greater specific impulse
Are rockets being used today?
This current day? What sort of rocket do you mean? If you mean a major rocket launch, no. If you mean over a large period of time, yes rockets are used for launching satellites and space station ships etc.
What is a type of motor that burns fuel without air?
A rocket motor (rocket engine) does not need air from the atmosphere. It carries the oxidant (source of oxygen) as well as the fuel.
