Seems it may take weeks for Team Atlas/Aerovelo to get their ďdata and footageĒ to AHS forĒ official validationĒĖ ďHopefully this process will be quick, but it may take several weeks.Ē

From - http://www.aerovelo.com/2013/06/14/take-a-deep-breath-and-hold-on-2/

I guess they must have complied with this rule . . .

ď4.5 Observation

Every attempt shall be observed by the NAC or a duly appointed representative of AHS International [amended 2/7/2013] or by any persons authorized by them to act as observers. It may take place in the competitorís own country if it is affiliated with the FAI. In a country not so, it could be advantageous to conduct the flight in a neighboring country which is so affiliated.Ē

How do you see the situation post-Sikorsky prize? Surely this won't be the end of the story.

Not sure what you mean. Obviously it will be the end of the competition. Do you mean it wonít be the end of HPH developments or another HPH competition? Perhaps a competition where the HPH has to complete some predefined course. And/or perhaps a new height requirement that takes the craft completely out of ground effect (a real chopper).

Donít see any reason to peruse with my effort unless thereís another competition with a substantial prize incentive. Are there any other human powered vehicle competitions waiting to be won?

I can see other goals besides winning the Prize. Setting world records for altitude or duration, perhaps. How about a machine that was unquestionably beyond ground effects, and could fly around a specified course? Only rotating wings allowed. All we need is for someone to offer a reward.

I don't think there are any HPAs even with fixed wings that have flown out of ground effect.

An HPH that could fly a course around a 10 meter box without going outside a 25 meter box would be interesting.

It would have to be outdoor which would make it even more interesting. I would be a contender if the prize money was at least $250,000.

Can't figure out with Team Atlas why they think it might take several weeks to get their data together. Is it really all that complicated? Perhaps they're just bluffing to put Team Gamera off their attempt.

Here's a clip on Team Atlas that includes their major crash - http://www.ctvnews.ca/video?clipId=9...ylistPageNum=1

Including the Gossamer Albatross?


Another video of Md.

I thought this was an interesting statement. Obviously true when you think about it.

If you think you can get the Gossamer Albatross to fly around a 10 meter square, without going outside a 25 meter square, have at it.

Think the question was if the Gossamer Albatross has ever or never flown above ground effect.

Correct. I always thought of ground effect as more like a hovercraft.

This link is to a webpage on ground-effect craft like the Ekanoplane.

This surprised me a little, because the rule of thumb I've heard bandied about is 1/2 span altitude.

Could the GA have flown out of ground effect? I don't know. Bryan Allen was quite an engine. But I'm pretty sure he never went to 150 feet AGL

I looked in the specs for max altitude for the GA, and never found anything. I always had assumed that he flew no higher because he didn't have to, and maybe was afraid of higher wind gusts. I don't know though. The picture of the Ekanoplane or futuristic planes like the Pelican Ultra were my idea of ground effect craft.

I wouldíve thought it would have as much, if not more, to do with the speed of the wing than anything. Wouldnít the same wing at 500kph experience more ground effect than one at 20kph at the same low altitude?

Team Gamera arenít waiting for Team Atlas to claim the AHS prize and have resumed test flying.. They also claim to have exceeded the required 3 metres - https://twitter.com/UMD_Gamera/statu...407171/photo/1

The race is still on . . .

As Team Atlas waits for the AHS to confirm they have won the Sikorsky Human Powered Helicopter Competition, Team Gamera invited them over to see them break a few records and share their info.

If there are other human powered competitions perhaps it might be best if I don’t know about them. Wonder if AHS will run another HPH competition?

I have a couple of wacky concepts that came from my brief HPH attempt that I might pursue (a least at a model level). They are a stationary wing hovering craft and a way of overcoming counter-rotation by using some of the energy of one rotation to stop the other (told you they are wacky).

ETA - Thanks to those that took part in this thread and offered their HPH advice and encouragement.

This may be a video of the winning flight - http://www.aerovelo.com/

Although there is a string dangling down (to help measure the height I think) tha didn't go above 3m. Maybe this was allowed.
