How To Build A Rocket?
Rockets have existed for hundreds of years carrying out different purposes
. They can be used for weaponry, fireworks, ejection seats, launching vehicles like spacecrafts for artificial satellites, human space flight and discovery. The original design of rocket was created in China and India for displaying fireworks. The word rocket is commonly used to refer to three different types of objects:
1.A flying vehicle used by astronauts to fly into space for discovery reasons.
2.A weapon that is fired from tanks toward an airplane.
3.A toy version of any of the above two objects that is used to practice or comprehend air launching or to propel fireworks into the air.
The only distinction between the rocket used to propel spacecraft into space and the one that is used as missile is how they are constructed. Spacecraft are built with a strong, short thrust that will get them into space since this is their chief goal. The rocket missile need to be maintained to make sure that staying power is kept at the requisite paradigm. Regardless of the type of rocket, they all use a related chemical reaction to launch the object into the sky. The chemical used to set off rockets may be gasoline, liquid oxygen or liquid hydrogen.
Making a rocket can be fun especially if you are working with children or if you just want to do something creative. You have two options to choose from either building one from scratch or buying a kit to compile. Your homemade rocket may not fly as high as one that you can purchase but it is inexpensive and the project is entertaining. It is important when building a rocket from scratch to draw out a simple plan beforehand. The instructions below will assist you to make one from scratch.
Required Materials:
Plastic Cylinder object (soda bottle is a great choice)
Nose cone
Fins
Balsawood
Wood glue
Plastic cement
Launch pad
Engine mount
Paper
Sand paper
Cotton bud
Paint
Parachute
Required Tools:
Engine
Small paintbrush
Ignition system
Pencil
Craft knife
Instructions:
1.Use the pencil to draw the plan on a piece of paper. It should have a cylindrical body, nose cone, three fins, and an engine.
2.Connect the nose cone to the cylindrical body and affix the parachute to the rear of the nose cone using plastic cement.
3.To make the fins, sketch the design with a pencil on paper then cut out the object from the balsawood with the craft knife. Use sand paper to sand the fins to make them smooth.
4.Use rubber cement to securely connect the fins to the soda bottle or your choice of cylindrical object.
5.Attach the engine mount to the object. It must be placed into the bottom of the rocket underneath the fins. In order to set up properly, take a cotton bud and apply glue to the exterior of the engine mount. Slide it beneath the fins in the bottom of the rocket. The glue should hold it into place.
6.Paint your rocket with several light coats for a more attractive look. Providing the paint is entirely dried, you can set off your rocket.
Tips:
It is imperative to sand the fins as air travels easily over smooth fins than rough ones.
When firing your rocket, be certain you do so in open spaces away from persons, animals, vehicle and power lines. This will decrease the risk of injury or damage.
You can try working with more fins or various styles as the fins are very important in determining the way a rocket flies through the sky.
