Manual launch pad system and rocket fuel
In Today’s article, we hope to talk about how to design a manual launchpad system for your model rocket. This system contains these main parts.
01) hold-down arms
03) launch rails
04) blast plate
This Hold-down arms will hold down your flight till liftoff. But disadvantage with system is, if this system doesn’t work at the moment it will be a great trouble for you. Then If you’re stranger for this subject hold down arms are not very important. But if you are going to use this special thing is you need to fix this hold down arms for blast plate correctly and most strongly. Otherwise this hold-down arms will automatically remove from the blast plate for the trust of your flight. According to your flight structure you can use about four or three hold-down arms.
blast plate and launch rail
Absolutely, you need at least two launch lugs on your flight if you’re using this launch rail. This part will help to your rocket for keep stability. Actually this is a very important part on your launch pad. If you’re making this yourself you can fix it to launch pad according to your own idea. But make sure to keep it straight.
How can we build these hold-down arms?
First of all you need to think about the purpose of this hold down arms. Then design this parts according to your ideas. Internet will be another helpful step for you. But make sure to build this strongly.
Actually, rockets can be divide into two main parts as solid-fuel rockets and liquid fuel rockets. Then these model rockets always belong to solid propellent fuel rockets. Then what are the fuels that we can use for model rockets?
5)Ammonium perchlorate(For larger rockets)
6)Black powder(same to gunpowder)
How can we buy these chemicals ?
Actually we can’t buy these chemicals without licence. Then the best way is contact a institution related in this industry or contact a rocketry institution. If this is hard way to you, get best gunpowder from Fireworks.
