- This addition of the explosive tutorial will explain rockets, their
- propellents, and their ignition systems.
- First of all I will be talking about the model rocket engines because
- they are very easy to obtain and can be converted for many of your needs.
- Your basic model rocket engine has three stages. It's first stage is it's
- propellent. It's propellent consists of a solid fuel composed of solid
- black powder. It has a clay nozzle on the bottom side to direct and
- concentrate the thrust out the back of the rocket. After the solid propellent
- burns out(usually depending on the engine, within half a second to two and
- a half seconds) the tracking smoke ignites. This is made specificly for the
- model rockets when they reach high altitudes. Then their is the ejection
- charge. That is usually made of a black powder that blows out the parachute
- with a minor explosion. Now if you are going to make a rocket that has an
- explosive payload, or something that makes a design(such as a sky rocket),
- you will need to scrape off the tracking smoke for it to have a shorter time
- between igniting your payload. It will fly to the ground before it ignites
- your payload if it is to heavy and does not have those powders scraped off.
- Now I will talk about the ignition system. It is electrical, unless
- you have a long enough fuse that will fit up the engine nozzle and give you
- plenty off time to run like hell. But, if you are using the rocket launcher
- then it must be electrical. If you choose to shoot it out of a pipe you
- can use the electronic detonator that I explained in one of my earlier files.
- They are ignited by using model rocket igniters that can be bought at your
- local hobbie store. You must make sure the two wires of the igniter are
- not touching or else the igniter will fail and not fire the rocket. You
- place the igniter in the bottom of the engine making sure you push it in
- far enough so that it touches the solid propellent but to not force it or
- else you might bend the wires causing them to touch. After the igniter is
- placed in the engine, you must then place something to keep the igniter from
- falling out. This can be done by placing an igniter plug in thier which
- usually come with the engines now-a-days. If you don't have any you can
- simply use a peice of tape that runs through the two wires holding it firmly
- in place. Never aprouch the rocket if it misfires for about a minute just
- in case. You don't want to have it go off in your face, because that would
- probably be an extremly rude awakening.
