| NEWTON'S LAWS & ROCKET PROPULSION | ||
Like a balloon, a rocket engine in its simplest form is a chamber enclosing a gas under pressure. The pressure is provided by the combustion (burning) of the fuel and oxygen (oxidizer). The resultant combustion gases then "escape" through a hole (nozzle), thereby propelling the rocket/chamber in the opposite direction. Rockets, from air-to-air missiles to the Space Shuttle's main engines, are basically the same and differ primarily in size and complexity of the engine hardware. |
