WSIKF AWE Report Part 2- KiteLab Demos
- 2009 was KiteLab's third year demoing AWE at WSIKF (Washington State International Kite Festival).Highlights-A tethered HotWing foil wowed the festival crowd on Thursday. Its truly the tip of a HAWT without all the excess structure. These wings are much hotter than the stock sport kites KiteLab uses for COTS AWE to drive a generator by a string A-frame or tri-tether. Kids loved it. Some kite pros thought it was uncanny, scary even, but on close inspection found it safe (low mass & soft).energykitesystems.net/DaveSantos/wsikfwing.mpgKiteLab's utility arch flew halyard experiments on Monday, arch & train day. Jason Jolivet assisted & proved an apt student. A finding is that kite arch/lattice halyards/haul line loops need to have both lines well separated by a spread fair-lead or twist-up is probable.energykitesystems.net/DaveSantos/lifterline.jpgThe above jpg was not exactly the configuration flown at WSIKF, its missing the the big HQ XXL sled. The scrap kite in the fore-sky, made from old tents, caused merriment. Its a serious example of a powerful utility pilot/lifter made from salvage material. Detail-energykitesystems.net/DaveSantos/scrapkite.jpgKiteLab's little "reference" flygen flew nicely all afternoon on Saturday.energykitesystems.net/DaveSantos/WSIKF2009Augustflygen.jpgOn Tuesday Iqbal Hussein, an invited kite star, helped set up & fly a small membrane wing mill generating electricity using John Borsheim's spragged flywheel generator. Detail-energykitesystems.net/DaveSantos/SpragGen.jpgDavid Gomberg, a top kite showman & manufacture, checked out KiteLab AWE tech for the second fest this year (Austin Kite Fest last March). He was amused by this macho KiteLab hyperwinder.energykitesystems.net/DaveSantos/multiwinder.jpgScott Slater was at WSKIF this year & confirms his 2400 sq ft Osborne pararfoil is available for AWE research. Here is a strange trick. He flies the kite low (~60 ft), which means its unstable, as the giant kite's loop frequency closely matches the tether frequency. Sooner or later, usually after an hour or two, it hooks into the ground & he bags it. This is how he manages to bring it down single-handed without fail!A Tal Streeter UFO was being flown at WSIKF on four lines & is surely the "sideways flying" wonder Drachen's Dave Lang & Joe Hadzicki wished for. Its a round hoop with fabric stretched across it & a hole in the middle. It originally sold as a sort of flying disc yo-yo.===============================Tomorrow is the One Sky One World kite peace fest here on The Peninsula. KiteLab will perform dual varidrogue & minimalist surf-zone energy experiments.
