how are rockets built?

Shoot for the moon.even if you miss it,you will land among the stars!

4 main rocket systems:

Rocket Parts

• structure system

• payload system

• guidance system

• propulsion system

structure system

INTRODUCTION HERE

all parts which make up the frame of the rocket:

• the cylindrical body

• the fairings (nose cone)

• any control fins

payload system

INTRODUCTION HERE

the amount of goods or passengers that can be carried by the rocket, e.g.

• cargo

• satellite(s)

• a space probe

the amount of goods or passengers that can be carried by a rocket

• a spacecraft carrying humans

guidance system

INTRODUCTION HERE

the equipment that provides stability for the rocket and controlls it during maneuvers:

• very sofisticated sensors

• on-board computers

• radars

the amount of goods or passengers that can be carried by a rocket

• communication equipment

propulsion system

INTRODUCTION HERE

all the parts which make up the rocket engine:

• the tank pumps

• propellants

• the powerhead

the amount of goods or passengers that can be carried by a rocket

• the rocket nozzle

Cylindrical body

Rockets can be various sizes but they are always cylindrical in shape because of different reasons:- aerodynamics (the shape reduces the area that is in contact with the air, which menas reduction of drag)- ease of building at large sizes- less weight of the rocket's walls

Fairings (nose cone)

The fairing is is conical in shape and it consists of two half shells. It is used to protect against aerodynamic, thermal and acoustic phenomena as the launcher rises from the launch pad through the atmosphere to an altitude of approximately 100 km.

Back

Control fins

Fins are used on rockets to provide their stability and control direction. It works in the same way as placing feathers at the tail of an arrow. The greater drag on the feathers keeps the tail of the arrow at the back so that the point of the arrow travels straight into the wind.

Back

Space probe

A probe is a spacecraft that travels through space to collect science information. Probes do not have astronauts. Probes send data back to Earth for scientists to study.

Back

Propellants: liquid and solid

In the liquid rockets the propellants: the fuel and the oxidizer are stored separately and then they are pumped into the combustion chamber of the nozzle where burning occurs.

In the solid rockets, the propellants: the fuel and oxidizer are mixed together into a solid propellant which is packed into a solid cylinder. They burn when exposed to a source of heat provided by an igniter.

Back

Powerhead

The powerhead is the top part of the engine and it is the section of the machinery that houses turbopumps and the ductwork needed to generate the thrust to lift the rocket into the space.

Back

Rocket nozzle

In the rocket engine , fuel and a source of oxygen (an oxidizer) are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through the nozzle to accelerate the flow and produce thrust. The nozzle is a relatively simple device, just a specially shaped tube through which hot gases flow.
