Rocket History

How are typical rocket engines configured?

Rockets are configured to combine fuel and oxidizer—two ingredients necessary for combustion—rapidly so there is tremendous burning or even an explosion. The resulting hot, expanding gas must be controlled in its output, both in amount and direction. The key is the exit of exhaust gases from the rocket, which is allowed to escape through ports or nozzles in one end. The forceful exit of the exhaust creates thrust that moves the rocket upward and forward.
