More than one type of Sikorsky Prize?

Apparently there are Sikorsky prizes other than the human powered helicopter one. Mil_Mi-12#Design_and_development mentions that the prize was given "for outstanding achievements in helicopter technology". —Preceding unsigned comment added by Anthonzi (talk • contribs) 05:32, 31 May 2010 (UTC)[reply]

There is no such thing as "The Sikorsky Prize". AHS International has "Igor I. Sikorsky Human Powered Helicopter Competition" and the "Igor I. Sikorsky International Trophy".

Value of Prize

Currently the article says that the prize is $250,000, but I can't find a source that verifies this. All the sources I've found have the prize at $20,000. I'm making the change until someone can show that they increased the reward. SselemanLuos (talk) 22:14, 7 December 2011 (UTC)[reply]

The prize is $250,000, as shown on the official AHS website. See http://vtol.org/awards-and-contests/human-powered-helicopter/hph-rules and http://vtol.org/22872130-E786-11E0-ABFF0050568D0042. I've changed it back and added some additional details and updated weblinks. Vertiflite (talk) 18:42, 6 January 2012 (UTC)[reply]

Initial value

http://www.vtol.org/hph says "AHS International initiated the Igor I. Sikorsky Human Powered Helicopter (HPH) Competition in 1980, with a prize of $25,000"

http://www.wired.com/2013/07/human-powered-helicopter-prize/ says "The AHS first put up the challenge back in 1980 and since then more than 20 teams teams have designed and built human-powered helicopters in an attempt to win what was initially a $10,000 prize." — Preceding unsigned comment added by 188.35.131.139 (talk) 12:12, 1 August 2015 (UTC)[reply]

Did the Atlas team really win this??? Seem's to have cheated.

I would like to challenge the award of the AHS Sikorsky Prize to the Atlas team on technical grounds that should have been raise long before now.

The Atlas team used the ceiling to create significant additional lift, using a "reverse ground effect" from the low pressure area above the craft during operation. This combined with ground effect higher pressure, allowed the team to nearly double, or more than double, the lift provided by ground effect alone.

I strongly believe the craft as designed would not meet contest rules on an open tarmac with clear sky above it.

In addition the roof controlled and restricted re-circulation of air flow, trapping the low pressure bubble above it, and high pressure bubble below it, that would not have happened in an open area without a ceiling.

With both the rotors and overall size of the craft substantially larger than the floor to ceiling height, this should have been obvious at the time.

This clearly games the original intent and expectations set when the prize was initially offered, in a very deceptive way.
