Mexican Rocket Trials

[Landotter1]

If the fins on the rocker were turned about the same angle as the engines, it may have flown properly!!!

[jvasquez311]

Teamwork FUCK YEA!!!

[kipyj]

pero si son puros gringos..

[hjfkds]

para que suban y no se les caigan tienen que girar y de un empuge el que ase guirar sale la mecha que prende todos mexico fire works

[ultrabluebear]

oh why wonder how it failed. :-)

girandola,s must rotate like a bullet.

and you guys made tailfins on them like a rocket.

so every time it would rotate(that,s the idea what a girandola does) it finds resistance from those 4 tailfins.

why does a bullet spins and must a rocket have stabilizer fins? because they both must be stabilized, if you give a spinning bullet fins it would go all places but not the right direction

and if you must give them fins give them curved ones that go with the flow

if i was there i would of duck and cover

Great Video!

[wtfmrkaffe]

Awesome ramming machine (around 0:45 in the video) :D 5*

[pyronaught]

I designed and built the ramming machine. You can get the plans for how to build it on the passfire website.

[displayfireworks1]

You guys look like you are all having a great time. Im jealous I live too far away in Pennsylvania. Was that one guy with the shorts Harry G?

[pyronaught]

Yep, the guy in the white shorts on the first rocket launch was Harry. I'm the other guy lighting the rocket.

[Ignantredneck]

epic fail.

[Ignantredneck]

haa haa all that work and they all sucked.

[knightmare77012]

boring

[tajmaishu]

Holy Shit!!

[durneykeypyro2]

Are you part of the florida pyrotechnics art guild?

[pyronaught]

yes. This video was from the FPAG spring festival in 2006.

[captainskidmark]

i like the scientists who actually analyze these flights and give their hypothesis as to why they don't fly..... my analysis is, for those who care, is that these guys have severe cases of erectile dysfunction and viagra no longer has any effect, and this is what results..... why am i wasting my time????

[captainskidmark]

they look like pinatas!!! me gusta bailar!!

[chernobilrasputin]

this is ours nuclear mexican weapon.

we will invaide all the countries hahahahaha

we have the power :-( well almos jijijijij

is fun

[pudidotdk]

simply too awsome

[moonsmilelucide]

rocket is to heavy, pretty cool though.

[pyronaught]

The rocket is actually not too heavy, the thrust is just not balanced so it can't maintain a straight path. If the rocket were too heavy, it never would have left the ground. They only get lighter as the fuel burns during flight, so it's not a power or weight issue. The major flaw here is that this type of rocket has to be spinning pretty fast on its vertical axis before it ever takes off. By spin-stabalizing them, they won't arc over the way they do here.

[moonsmilelucide]

aha yes I see now, the first few meters it goes well and then it becomes out of balance. so your right not to heavy ;)

[nicksynnz]

Why not make the centre of pressure lower than the centre of gravity and the rocket a bit taller and it would fly fine.

[jackmonkey26]

That doesn't work for low speed ascents. On girandolas the spin is used to stabilize the object. The only other way would be to make sure the CG is below the center of thrust like a stick rocket and that can be unstable at times. A little tweaking will fix them right up.

[D4nt0r]

how can it spin before it takes off? And what causes the spin?

[pyronaught]

It needs horizontal drivers that are attached sideways on the wheel in opposing pairs. The horizontal drivers fire first, then after about 6 seconds of spinning, the vertical drivers fire.

[thomashagenbeek]

this is awesome man! could use some edits though but who cares.

[DAltar]

nice maltese driver tool
