All About Rockets

History of Rockets

  • Definite origin of rockets is unclear.
  • First century AD.
  • Many experts believe Chinese discovered rockets by accident (explosions during celebrations using gunpowder).
  • Filled bamboo tubes with gunpowder.
  • Escaping gas propelled the “rocket”.

will be a history of rockets, compiled from all classmates' findings.

Components of a rocket propulsion system

This will include diagrams and explanation of all parts of a rocket propulsion system, compiled from all classmates' findings.
•The Body of the rocket is the green cardboard tube
•The Fins can be made of either plastic or balsa wood and are used to provide stability during flight.
•The Engine Mount is fixed to the rocket and can be made of heavy cardboard or wood.
•The Recovery wadding is inserted between the engine mount and the recovery system to prevent the hot gas of the ejection charge from damaging the recovery system.
•The launch lugs are small tubes which are attached to the body tube.
•The shock cord is connected to both the body tube and the nose cone and is used to keep all the parts of the rocket together during recovery.
•The nose cone can be made of balsa wood, or plastic, and may be either solid or hollow.

Key concepts in rocket propulsion

This will include diagrams and explanation of these key rocket concepts, as well as any other important ideas, compiled from all classmates' findings.

Thrust-Thrust is a mechanical force which is generated through the reaction of accelerating a mass of gas.
Pulse- To emit particles or radiation periodically in short bursts.
Newton - •The SI unit of force, equal to the force that produces an acceleration of one meter per second per second on a mass of one kilogram.
Burn time- The total operating time of a rocket engine.
