Wind Power - Div B

(section: 3 / paragraph: b / line: 1)

2015-11-12 14:33 Is the CD that the blades are mounted to only held on to the generator by the detent balls on a CD player or can extra support be provided such as double sided adhesive tape to strengthen the joint?

Yes, as long as the tape is easily removable and does not impact other subsequent teams' testing.

(section: 4 / paragraph: l / sub-paragraph: ii / line: 1)

2015-11-12 14:35 Rules state that "Power generator general questions...."Does this refer to the general question of how electrical power is generated in each of these types of power plants or specifically to the generator itself?

Anything related to power generators in general is a valid question, which could include aspects of the power plants.

Air Trajectory

(section: 3 / paragraph: c / line: 1)

2016-01-29 19:17 Can we re-inflate the air chamber after launch (ie: soda bottle, when it's crushed) using ambient air, to go back to it's original shape, or does it need to re-inflate itself?

Yes,you may re-inflate the air chamber provided the chamber is at ambient pressure at launch.

2015-12-14 09:24 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.

(section: 3. / paragraph: f / line: 1)

2015-11-12 13:04 Team must provide unmodified light weight plastic or foam golf balls to be used as projectiles. Are practice plastic golf ball with holes on the side consider "Unmodified"?

Yes, plastic golf balls purchased with holes in them are considered unmodified and are allowed.

(section: 4 / paragraph: b / line: 1)

2016-01-15 20:16 May competitors be in front of the launch area BEFORE a launch? Specifically: Are competitors allowed to walk behind targets to instruct their partner in aiming their device?

General rule #1 applies (https://www.soinc.org/ethics_rules). There is no prohibition in the rules about approaching or going behind the targets prior to a launch during their 8 min. time period (rule 4.f.) During a launch they must follow rule 4.b. Teams may be penalized if they disturb the competition area.

(section: 4 / paragraph: f / line: 1)

2016-01-14 21:09 Can competitors use a laser as a material to help with setup, adjustment, and calibration of the device? General rules about laser use will be followed and the laser impounded.

Yes, lasers may be used as a tool for setup, adjustment, & calibration of the device. They must be removed prior to launch. The laser policy posted on the National website must be followed.

2016-01-15 20:19 Is a rope which extends from the device to the target considered a calibration tool?

A rope can be considered a calibration tool as long as it is removed from the device during each launch.

(section: 4. / paragraph: e. / line: 2-5)

2016-01-15 20:26 The rule says a distance of at least 2.00 m must separate the targets. If the near target is on the 2 m centerline would it be legal for the far target to be 2m to the right or left perpendicular to the centerline 2 m mark?

Yes, that is allowable.
