What does the engine do on a space rocket?
Provide thrust ... which changes velocity.
What are two ways to increase the amount of thrust a rocket produces?
If the mass flow rate through the rocketâ??s engine is increased, then the thrust will be higher. Another way to increase the thrust amount is to increase the exit or initial velocity during takeoff.
What is thrust for a jet engine?
The thrust of a Jet engine is calculated through the formula: F=(m_air+m_fuel)*v_e - m_air*v Where m_air is the mass flow rate of air entering into the engine m_fuel is the mass flow rate of fuel entering the combustion chamber v_e is the exit velocity of the exhaust gases (where v_e needs to be subsonic) v is the velocity of air entering the engine As you can see the thrust is reduced by the term m_air*v which physically has the significance of a drag at the intake of the engine. That's why rocket engine give usually a better thrust. Since they carry the oxidizer on-board that term doesn't exist for a rocket engine. I will let you think about the parameters you can play with to design an engine with as highest thrust as possible for a given (fixed fuel consumption). hint:v_e is influenced by things like combustion temperature, combustion pressure etc... Hope this helps!
What is the simplest engine that is made of a burning chamber and a nozzle?
rocket engine seems to be of this type. as the air-fuel mixture is burned and flame is made to propogate through nozzle to provide thrust
What two factors should you keep in mind when designing and building a rocket?
When designing and building a rocket, it's crucial to consider the rocket's structural integrity to withstand the intense forces during launch and ascent. Additionally, the choice of propulsion system significantly impacts the rocket's efficiency, thrust, and overall performance. Balancing these factors ensures the rocket can achieve its intended mission while maintaining safety and reliability.
What are two thrust factors that a rocket engine depends on?
•Thrust depends on two factors: -rate at which momentum leaves the rocket through the nozzle -Exit pressure pexit
On what factors acceleration of rocket depends?
The acceleration of a rocket depends on the thrust produced by the engine and the mass of the rocket. A higher thrust will result in greater acceleration, while a higher mass will decrease acceleration. Air resistance can also affect acceleration, with lower air resistance allowing for greater acceleration.
What if the rocket is going up what is the force?
The force pushing the rocket upward is the thrust generated by the rocket engine. This thrust overcomes the force of gravity pulling the rocket down, allowing it to ascend. The magnitude of the force depends on the design and power of the rocket engine.
During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
During a rocket launch, the thrust of the rocket engine is greater than the weight of the rocket. This is necessary for the rocket to overcome Earth's gravitational pull and lift off into space. The thrust generated pushes the rocket upwards while gravity pulls it down.
What is the forward force produced in a rocket engine?
Thrust
What is propulsive force of a rocket engine called?
The propulsive force of a rocket engine is called thrust. It is the force that propels the rocket in the opposite direction to the exhaust expelled from the rocket engine.
What does the thrust of a model rocket depend on?
The size of the engine you put in it.
What does the engine do on a space rocket?
Provide thrust ... which changes velocity.
Working principal of rocket?
Rocket engines obtain their thrust in accordance with Isaac Newton's third law, making the rocket a reaction engine. A rocket engine is simply a jet engine.
What is Rockets reaction force?
Rocket reaction force, also known as thrust, is the force exerted by a rocket engine to propel the rocket forward. This force is generated by the combustion of fuel in the rocket engine and is directed opposite to the direction in which the rocket travels. The magnitude of the thrust determines the acceleration of the rocket.
How can the designer of a solid rocket engine make the engine produce different amounts of thrust?
The thrust of a solid rocket engine depends on the composition of the solid fuel and the rate at which it is burned, and to some extent on the way the gases are directed by the exhaust nozzles. The same material can be burned at different rates to produce more or less thrust, and the nozzles (also used for directional control) can divert this thrust to control velocity and stability.
A rocket uses an engine that creates thrust throughout the combustion of a liquid fuel and an oxidizer what kind of rocket is this?
Chemical rocket
