coil gun canon
Oh god! Its raining metal projectiles!! Hey wait, thats kinda pretty. | |
2 coil guns setup at 45 degree angles on
stationary pedestals a good distance
apart. In the center of the line of fire a
marimba like tone generator (made of
iron
to withstand the projectiles) is placed. It
is
tuned diatonically from left to right.
The
idea is for a composition written
rhythmically as a canon for the two coil
guns. The composer must also denote
the
power said guns will use to launch said
projectile to achieve different notes.
I think it would work best in a large
gymnasium type place, to minimize wind
resistance. This would also allow the
lights
to be shut off and the room to be lit with
blacklights so the fluorescent painted
projectiles paths can be seen.
It would be really interesting to both try
and compose and to watch since
projectiles fired with a smaller velocity
will
impact the marimba-like thing sooner
that
a higher velocity shot fired before it.
Also, since it is a canon, shots fired from
the left will result in different notes than
shots fire from the right with the same
initial velocity.

So, something going SLOWER and fired LAST will hit the target SOONER than something going FAST that was fired FIRST? |
|
| |
Am I the only one that this doesn't make sense to? |
|
| |
Pretty much [MJ]. Slower projectiles travel much less distance. |
|
| |
[MJ]--
slower projectiles also don't travel
nearly as high. |
|
| |
heres an experiment for you. |
|
| |
take 2 tennis balls. throw one as hard
as you can straight up and then
immediately toss one over your
shoulder with little force. which one will
hit the ground first? |
|
| |
Here's one for you. If you take two tennis balls and throw one into the forest. If no one sees you throw it or hears you throw it, then how do you know if you really////RHUBARB//// |

position=
P(x,y)=v(x)t+v(y)t-.5a(y)t^2 |
|
| |
which can be broken into x and y
equations |
|
| |
since the aforementioned cannons are
at 45deg angles with the horizontal, v
(x)=v(y) |
|
| |
say a projectile is fired with a y velocity
of 1m/s |
|
| |
we can solve for when y=0 for when the
projectile hits the ground and find the
time by the equation V(y)=Vo(y)-gt ,
where V(y) is the final velocity of zero
when it hits the ground, Vo(y) is the
initial velocity (1m/s), g is acceleration
due to gravity (9.8m/s^2) and t is time (in seconds) |
|
| |
if the same projectile is fired at .5 m/s
it will hit at |
|
| |
I haven't taken kinematics in a while so
please correct me if I'm dumb. |

Very clever:
1. Cannon = Bang!
2. Canon = (Type of stringed) Musical instrument.
3. Canon = Musical style. |

I imagined, at first, that the notes would be hanging vertically above each other, so that after striking the metal plates, the projectiles would fall to the ground. When the plates are horizontal on the ground, the projectiles may bounce onto neighboring plates. I suppose they could be angled so that the projectiles bounce to one side. |
|
| |
Yeah sorry bleh. Did not realise what you were discribing was like a xylophone on the ground between your two cannons. Was also imagining something more spectacular and ariel. |
|
| |
I considered that, but then you wouldn't
get different notes from each gun. It would
be a true canon. My vision is a canon only
in the rhythmic and power sense in that
each gun fires projectiles with the same
power in the same rhythm but one is a bar
or two behind. I was thinking of angling
the bar on the xylophone type thing to
avoid bounces but i guess i forgot to type
it in the idea. thanks <ling> . |
