Understanding Rocket Engine Combustion: What Causes the Fire at the Bottom of a Rocket?

Learn about the combustion process in rocket engines and what creates the fire at the bottom during launch.

24 views

The fire at the bottom of the rocket is caused by the combustion of fuel and an oxidizer in the rocket's engines, generating hot gases that are expelled at high speed, creating thrust. This process, known as rocket propulsion, allows the rocket to lift off the ground and travel into space.

FAQs & Answers

  1. How do rocket engines work? Rocket engines work by burning fuel with an oxidizer to produce hot gases that create thrust.
  2. What fuels are used in rocket propulsion? Common fuels include liquid hydrogen, kerosene, and solid rocket propellants.
  3. Why is combustion important for rockets? Combustion provides the necessary thrust to overcome Earth's gravity and propel rockets into space.
  4. What happens during a rocket launch? During a launch, the ignition of fuel and oxidizer produces thrust, lifting the rocket off the ground.
