Below we will consider an example of creating a flying rocket. Its length is as much as two meters, and a diameter of 90 mm. A solid fuel rocket flies. IN homemade a rescue system is provided. Going to model quite quickly and requires a minimum amount of materials and knowledge.
Materials and tools for manufacturing:
- epoxy resin;
- seklotkan;
- gypsum;
- balsa;
- ropes;
- sugar and nitrate for fuel.
Of the tools you will need: a soldering iron, a hacksaw, a drill, glue and screwdrivers.
Rocket manufacturing process:
Step one. Body manufacture
To make the case, you will need fiberglass. A PVC water pipe is used as a mandrel.
Step Two How to make stabilizers
Stabilizers need to be cut from balsa.
Step Three Rescue system device
So that the rocket does not crash on the ground during a fall, a rescue system is provided in it. This system is a parachute that is released by an expelling charge. As a result, the rocket does not fall, but gently lands. To activate the rescue system, a special electronics with altimeter.
The missile consists of two parts, the engine is located in one, and the rescue system in the second. The expelling charge is in the plug, how exactly, you can see in the photo. How the rescue system works can be seen in the video below.
Step Four Electronics Installation
In order to install electronics, you need to make a small hatch in the rocket body. Well, the entire installation process can be seen in the photo.
Step Five Rocket engine
The homemade engine is made of fiberglass. As a charge, caramel fuel in the form of drafts is used.
The engine is attached to the housing from the outside using self-tapping screws.
Step Six The final stage of the assembly and launch of the rocket
At the last stage, the author finally collects the rocket. The whole process of improvements is clearly visible in the photo.
Here's what a rocket fairing looks like.
That's all, the homemade product is ready. How it works can be seen in the video.
