Launch of paper with his own hands

Launch of paper with your own hands can be created in a simple manner.

Before you start making the layout of the rocket should be defined with a scale model.

It must be remembered that these missiles have a certain aspect ratio (the ratio of the diameter of the missile to its length) or lengthening it is necessary or desirable to comply.

elongation ratio adopted appropriate intervals, from 1:10 to 1:20, i.e.Missile length should be not less than 10 times greater than its diameter, but not more than 20 times.

This ratio is dictated by the demands of aerodynamics and maximum power of the armed missiles.

Further, to make the hands of the paper, it is necessary to prepare all necessary.

Launch of paper with your own hands can be created for the model that will be carefully stored on a shelf and not be subjected to loads.

In other words, a rocket from a paper with their own hands will not have the strength for gaming purposes or frequent transportation.

So ...

1. Prepare a cylinder of any material

on which the paper is wound.

can do without cylinder and cylinder roll of drawing paper hands in the air.But it will not have the exact shape and size of the diameter.

cylinder material can be anything from wood to plastic and metal.

size cylinder diameter and length will depend on your choice of the ratio of the rocket.

For example, if you select the elongation ratio 1:10, then the model diameter of 5 cm, its length is 50 cm. If you choose elongation ratio 1:15, then the model diameter of 5 cm, its length is 75 cm.

That

if one selected diameter, for example a 5 cm length of the model rocket can vary from 50 cm to 100 cm.

In another diameter lengths will be different according to the selected elongation.

Aesthetically, the elongation ratio of 1:10 is more attractive.A paper model will be stronger.

advisable to revise the model parameters (diameter and length) on the basis of what size the cylinder is available for work.

2. Prepare a sheet of drawing paper of a suitable size.

advisable to revise the model parameters (length) on the basis of what size drawing paper available for work.

3. Prepare the glue.Better use of PVA glue marks.

4. Prepare a piece of foam for a rocket fairing, (you can make a cone out of paper).

5. Prepare the paint or colored paper for the cover model.

6. Prepare scissors, a blade or a sharp knife.

7. Prepare material for the stand model (foam or cardboard).

From the description of the preparation is already clear, however, how to make a model rocket with their own hands.

cylinder is used for the manufacture of the rocket body, which is created by winding on a poster board.

After the first round of drawing paper fluff need to glue the entire length of the first "lap" turns.This prevents the spring effect of stresses and turns in the turns of drawing paper.

After winding drawing paper, glued to the edge of the sheet "body" wound cylinder.

After drying glue cylinder is removed from the shell, obtained from a sheet wrapped around poster board.The case is ready to launch.

fairing for the rocket can be cut or retractable blade knife office of foam and glue it to the cylinder of drawing paper, inserted into the opening of one of the ends.

The same can be made of paper, which is a bit more complicated, becausefor bonding the cone needs to be done drawing layouts.Drawing cone must consider "skirt", which is used to "fit" of the cone into a cylinder and gluing it.

Bottom model must also be closed.It can be made from foam, cut out the right size for the stub.If the plug of paper making, it is necessary to make the drawing of cutting as well as in the case of the fairing.

Additionally, you can stand to make and the model of the foam.

The same can be made of paper.Then stand model must take a piece of thick cardboard.

exterior design of the model can be given via labels of colored paper or paint its colors.

Each missile must be marked, and it must be applied to the model.Then the rocket out of paper with your hands can be considered a complete model.
