VA Addendum

Description

A team will construct a helicopter device which uses one or more helicopter rotors to safely transport a raw chicken egg from a specified height to the floor.

Event Rules

In the National Event Handbook, received upon registration.
Alteration: The VA Addendum outlines a change in the release mechanism - helicopters will NOT be released by hand, but will instead need to attach to the release mechanism.

Clarifications

During our State tournament, we will enforce clarifications issued by BOTH the National organization and by VASO. In the rare instance that these clarifications are in conflict, VASO clarifications shall prevail over the National clarifications.

For the State tournament, the last day to submit clarification requests is Mar 10. VASO will post outstanding clarification responses for States by midnight 3/12/14. Also, we will NOT enforce any National clarifications for States that were issued after 3/12/14.

National Clarifications

Check both Official Rule Clarifications and National Rotor Egg Drop Clarifications for national clarifications pertaining to this event.

VASO Clarifications

March 12, 2014
General Construction - Students may not use parts manufactured by a 3D printer as part of their devices.

Rule 3a - Judging of the parachute rule will be more stringent at the State tournament. The covering on the rotor should be taut so that when the device is dropped, the covering does not visibly bulge, which creates the presumption that the rotor is capturing air. Also, devices with curved surfaces such paper plates or bowls, unless substantially modified, will likely be deemed to capture air and act as a parachute.

Rule 3a - Only blades or wings can slow the descent of the egg, so other items that produce drag (such as streamers) are disallowed.

Rule 3c - At the VA State tournament, the device will be measured and massed without the cup attached.

January 29, 2014 (Rule 3a) Can the rotors be curved to catch air if they still rotate around a central point?
If a vehicle does not rotate, it is most likely a parachute. However, a rotor that rotates may still be ruled to be or have a parachute. If the rotor captures air, it will be considered a parachute. Covering on the rotor must be taut so that when the device is dropped, the covering does not bulge, capturing air. The determination of whether something is a parachute is in the best judgement of the event supervisor.
December 12, 2013 (Rule 3e) Does "fit" mean that the entire device can be inserted and removed from the cube without disassembling and assembling prior to flight (i.e. can be bent within the cube and can be touching the walls), or does "fit" mean that the entire device has to be inserted in the cube without any of its parts touching the walls?
The device must be in flying configuration during measuring, therefore it cannot be disassembled. The device may touch the walls of the cube during the measuring, but if it is deformed by being in the cube, it will not be in flying configuration and will be considered in violation of the construction rules.

Rule 3b - No plastic bag will be used. The students will place the egg directly into the provided cup in such a way that some part of the egg is in contact with the bottom of the cup.
