Air Trajectory B/C

[BananaPirate]

If the ball is shooting too far, can I put another projectile in it with the ball so that the air moves the first projectile into hitting the ball? Would I be disqualified if the first projectile comes out?

The common approach to this is raise the angle of the launch tube and/or reduce the weight of the mass.

In order to lower the power of shots as a whole, my team has made it less efficient by shortening the length of our tube/barrel and putting a hole in the tube with the ball.

we use a weight that falls down a tube design, but we had to shorten our tube. To get it to shoot farther, I drilled about 150 1/4 in holes down the side of the dropping tube. Our machine can shoot over 10 meters

I've taken a similar approach, but mine can only shoot ~6m. What would you suggest to use for the weight and how far down the pipe did you drill?

Hi, anyone know if Air Trajectory is on a 2 or 3 year cycle? Will it be replaced next year?

Thanks!

It's a new event, which means that the 2015 season was the first year it was run. According to the proposed event list for next year (https://docs.google.com/document/d/1MtP ... EB2XM/edit), Air T doesn't seem to be coming back for the 2017 season (dang, 2017...I feel SO OLD). It appears that it will be replaced by Optics (as far as I can tell).

Wait, isn't optics replacing crave (division b)/IAT (division c)?

Yes that's correct. Sounds Of Music is tentatively replacing air trajectory I believe

Yep, I believe so too.

Hi I have a rules question.

Are we allowed to use a stop watch during the resetting of our device? We want to be able to keep the amount of time between when we stop blowing and when we put the ball in consistent. The rules say that no electronic components are allowed, but I'm pretty sure laser pointers are allowed, so I would think that stop watches are allowed too.

Thanks in advance!

According to the FAQ on Soinc.org:

2015-12-14 10:24 Can the calibration of the device be electronic, if it is not a physical part of the device? (Meaning, it can be added, calibrated, and then removed before the firing of the device).
Yes, tools are allowed to be electronic. Electronic devices may only used during calibration.

I believe this means a stop watch can be used during calibration. You might want to check out https://www.soinc.org/node/478 for further clarification.
