Understanding Rockets: Fuel, Mechanics, and Historical Development

Rockets are essential for space exploration, driven by the principle of Newton’s 3rd Law. They contain significant amounts of fuel, often twenty times the weight of the orbiter, and utilize various fuels like kerosene, liquid oxygen, and hydrogen. Early rockets emerged for combat, with pioneers like Dr. Robert H. Goddard innovating with liquid fuels. Booster rockets provide necessary thrust at launch stages and are discarded when spent. Advanced ion rockets present a more efficient propulsion method. However, space debris remains a concern for orbital missions.

  1. ROCKETS How Do They Work? By: Sam Houff 5-5-05

  2. Fuel • Rockets have lots of fuel • The fuel weighs twenty times the orbiter. • The fuel is used up quickly

  3. Fuel • Dr. Robert H. Goddards early rockets used a combination of Gasoline and Liquid Oxygen • Apollo Boosters- Kerosene and Liquid Oxygen • Space Shuttles: Liquid Hydrogen and Liquid Oxygen.

  4. How Does A Rocket Work • Rockets rely on Newton’s 3rd Law. The Law states that for every action, there is an equal and opposite reaction.

  5. Early Rockets • Early rockets were used in combat. The earliest date to China. • Dr. Robert H. Goddard developed one of the earliest liquid rockets.

  6. Booster Rockets • Booster Rockets are the rockets that thrust space shuttles into space. They are needed because of the shuttles lack of thrust power.

  7. Booster Rockets • A shuttles first stage of rockets are the boosters. • The booster rockets are dropped back to Earth after there fuel is used up, leaving only the shuttle.

  8. Ion Rockets • Much more efficient than a normal rocket. • Works by stripping neutrons from the atoms, therefore harnessing the positive energy.

  9. Obstacles of Flight • Space debris • Shuttles dump trash in space • The red areas on the picture are space debris.

  10. Bibliography • None. “How Rocket engines work.”Howstuffworks.com 5/02/05. <http://www.howstuffworks.com/rocket> • Wernher van Braun. “Rockets”. World Book Encyclopedia. 1975. Field Enterprises Educational Corporation. 4/25/05. • Unknown. Rockets. 2005.

  11. About Me • My Name is Sam Houff. I’m 5’3 and 13 years old. I love the Tar Heels and the Panthers. And I like sports cars.
