5. IDENTIFYING ROCKETS AND PARTS OF ROCKETS

Most rockets have very few external parts, though in­ternally some of them are extremely complicated. The body which encases the inner parts of a rocket is known as the air frame. This houses the combustion chamber, the fuel tanks, the devices by which the rocket is guided, and the nose cone. The nose cone, which is located at the upper tip of the rocket, is where the warhead or payload is carried.

At the lower end of the rocket are the exhaust noz­zles through which the propelling jets of gases escape. (See Plate 6.)

Rockets vary in shape and size, no two being alike. Some are tall and slim; others are short and stubby. Some have wings and fins and resemble jet fighter planes, while others look like enormous bullets.

Plates 7 and 8 show silhouettes of the famous rockets in this book. These are drawn to scale to show their relative sizes. Remember the size and shape of each rocket and you will be able to identify it.
