Welcome on D3scene.com! Make sure to 
the support shell
Posted 04-30-2008 at 05:54 AM by 35yeros
so here it is, the long awaited 35 boom boom support shell!!!
background: this isn't much of a project this is more of a, extreme project that i felt wasn't worth posting in g/c because it seems totally insane.
it is insane. don't try doing it unless you really want to.
alright, here the math stuff.
next get alot of card board and build a wide cylinder and make it about 4 feet tall.
attack 3 to 4 fins made of cardboard that is reinforced with metal strips (put little metal strip's in the cardboard)
this is called the support shell
next cover the card board with tin foil, this will protect it form the heat/elements it will have to go through when its launching, (keep in mind this is going to be flying at over 350 miles an hours)
then to further increase its restancy,
paint it with gloss paint
use indistral grade tin foil
double layer
now weigh the support shell,
now figure out how much force you will need on each side of the rocket shell,
this is what i did.
start by attaching 10n (10 newtons) of force to each side, at the area in between the fins. i used 10 rockets, which stretched all the way around the rocket.
equation:
a is the weight
c is the rocket power
y is the rocket weight
dB is the tagert range
dct is the overall force being exerted on it at maxium force.
now make a secondary iginitoion wire. (this will lite the second and third rocket rows off)
this is a crucial step in building a support shell.
if the second stage doesn't go off, the rocket will come screaming back down. if its empty and comes back down it will reach a speed of 890 mph, or fast enough to burn up. so if its got a project in it, it will go even faster.
ignition wire: your going to have to make 1 wire for ever link, i had to make 25+
10 inches of twine that has been soaked in gasoline, and anything else that is flammable.
coil it a few times on the top of the fuel in the rocket, then run the rest into the 2nd stage rocket, then plug it with a capasitor, not the normal plastic plugs that come with the engines, they will melt.
and do this for as many stages as you need
if were linked here by one of my other guides, there may be some mods you need to do.
and thats it.
