Re: pneumatic launch velocity
Quote:
Oh sheesh, I'll do the math v^2 = 2 * a * d (12 m/s) ^ 2 / (2 * 1in / 39.37in/m) = a a = 2834.6 m/s^2 so... 1/2 * a * t^2 = d t = sqrt ( (1/39.37) * 2 / 2834.6) t = 0.004 seconds. I'll say (from experience) I haven't seen pneumatics move 1 inch in 4 milliseconds. I think there's a lot of time required to have adequate airflow from the tanks to the piston, and like I alluded to before, I really think there are vicious damping issues that arise. Hence, it's my personal recommendation that you do not count on having a directly driven ball launcher using a pneumatic cylinder. However, I feel pretty confident that you could come up with something with some mechanical advantage ideas that was previously mentioned. Matt * an admittedly stolen disclaimer of Dr. Joe.
