PRESENTATION OUTLINE
There are four major systems for the parts of a rocket. There is the structural system, the payload system, the guidance system, and the propulsion system.
The structural system is basically the frame of the rocket. It is usually made from strong, lightweight materials like titanium. Fins are added for stability and a pointed like cone on the top of the rocket to make it more aerodynamic.
The payload system depends on the rockets mission because that is where things are stored in the rocket. Today it is used for fireworks and explosives for war.
The guidance system contains computers, radars, and communication equipment. Also, the guidance system uses a nozzle to maneuver to make the rocket more stable.
The propulsion system takes up most of the rocket. There are two types of propulsion systems. One example is a liquid engine. A liquid engine includes fuel, tanks, and pumps.
History
The Chinese were the first recorded users of the rockets in century A.D.
They used rockets for colorful displays and for religious festivals. The rockets were used between 1200 and 1300 A.D. and were made of sulfur and charcoal.
Modern Rockets
Dr. Robert Goddard was credited for making the first rocket and is known as the father of modern rocketry. In 1926 he successfully tested the first liquid fueled rocket. Years later the modern rocket put Neil Armstrong and Buzz Alden on the moon in 1969.
Rockets Today
Today rockets are used for many different things. For example, they are used for fireworks, weaponry for war, ejection seats, human space flight, and space exploration. The people who use rockets today are soldiers who use it for bombs and war. Also, astronauts and scientists use rockets to observe space and planets and to send the astronauts out to space for experiments.
Rockets have come along way since the earlier days many years ago. In that time there was only tubes filled gunpowder. We slowly developed liquid fueled rockets, and now the modern rockets that we know today that send astronauts to space and can be deadly to enemies in a war.
