| 366.1 | Hydrofoil-cycle | BUFFO::BUFFO | | Mon Jun 29 1987 10:46 | 13 |
| What you describe sounds like the bicycle powered hydrofoil
designed by mechanical engineering professor David Gordon
Wilson of MIT, a recumbent enthusiast. He wrote an article
for the December 1986 SCIENTIFIC AMERICAN which illustrated
the machine on its cover. As I recall, the hydrofoil was
roughly equivalent to a crew shell in speed. As I think
about it, that seems remarkably fast, so my cycling-biased
mind may be playing tricks on me. The article was quite
interesting.
Regards,
David Buffo

Re:.1
Thanks for the info, I'm going to try to find the issue. The team
originally tried launching it from giant slingshot-type device bolted
to a dock, rather than having any floats at all, but the sudden
thrust accompanied by the sudden slow down when he hit water proved
to be to rough on the rider. The bike had a large two-bladed prop
behind it, not unlike a plane propeller in appearance and it rotated
deceivingly slow. If this was the same vehicle as in the article
I would not be surprised if a well trained bicycle racer couldn't
easily match a crew shell. I couldn't believe the speed the competitor
drove th crazy thing at.

| 366.3 | Alan Abbot's 'Flying Fish' | EUCLID::PAULHUS | Chris @ MLO 8-3/T13 dtn 223-6871 | Mon Jun 29 1987 12:20 | 8 |
| The vehicle mentioned is Alan Abbot's 'Flying Fish'. It has
been well described in 'Human Power, the Journal of the Human Powered
Vehicle Association'. Dave Wilson is the editor of HP. He may be
the author of a SA article, but he is not the designer.
This year's IHPVA Speed Championships will be held in October
in Washington, D.C. The waterborne part of the competition will
be held in the Tidal Basin, just in front of the Jefferson Memorial.

| 366.4 | Human Powered Helicopter?! | DEBIT::FISHER | P-B-P qualified | Tue Jun 30 1987 06:49 | 14 |
| Excerpted from the April 17 issue of the International Randonneurs
newsletter which excerpted a longer article from the January 1987
issue of IHPVA:
HUMAN POWERED HELICOPTER FLIGHT TESTED. Michael Bruce, a manufacturing
and design engineer for Reynolds and Taylor, Inc. of Santa Ana CA,
has completed and flight tested a human powered helicopter. ...
Four 14-foot crimson rotor blades dominate the craft. ...
No attempts at actually free-flying the craft have been performed
... [that was last year, who knows what has happened by now]
R&D costs in the neighborhood of $100,000.

| 366.5 | looking for more info on IHPVA in DC in Oct | TALLIS::EBARTH | | Wed Sep 09 1987 14:46 | 7 |
| re: .3
Does anyone know the exact dates of the IHPVA Speed Championship
in Washington DC? Are tickets required? I assume it is outdoors.
Any additional info would be appreciated.
