Retrofit

I am a Spanish pilot who've developed a wing tips system adaptable to different gliders.  After several months of testing and trials with prototypes I've finally decided to advertise these devices through a web page that I've posted: http://rakedwingtip.wordpress.com/

Given the obvious (though subtle) aerodynamic improvements that raked wing tips provide, I'm sure that in the near future all the main hang glider manufacturers will offer these kind of wingtips.  I know that Wills Wing is also about to introduce this new option (I got in touch with Steve Pearson just to get their opinion and to share experiences, wherefore I am very grateful). Their ability to achieve high product reliability and quality is guaranteed.

Regarding Icaro 2000, they already have it as option.

Composite Rakedtips, however, are designed to be incorporated into gliders that already exist.  They also allow customization, not only aesthetic considerations, but in sizes and degrees of flexibility.  On the website I try to explain the key factors that affect Composite Rakedtips configuration and behavior.  Anyway, we clearly still have much to learn about the possibilities of wingtip devices.

Steven Pearson <<Steve>> writes:

Yon and I exchanged some emails discussing development and flight testing of raked tips.  Yon’s composite configuration is unique and may have some advantages for durability and retrofitting on older gliders, and the photos he provided certainly look nice.  Our configuration remains a laminated foam/fabric sandwich with carbon rods as stiffeners.

Sails produced before the end of January 2014 will have to be modified to add Velcro to secure the tips.  We don’t have a general release date yet but I expect them to be available by the end of February.

In my experience, the differences in flight behavior are subtle may not be readily apparent to all pilots.  I find that the stall angle of attack is increases slightly, and that controllability and sink rate with VG activated improves slightly.  All of these effects are limited to the slow end of the speed range within a few mph of minimum sink.

It looks like the snake forms its body into a figure eight so that it forms the shape of a wing.  The head and tail are center.  Seems obvious that it makes a high aspect ratio wing as best as it can with a body that resembles a stick.  Amazing.

The day by day story of how Jonny set his world records

The full story here.

January 17, 2014

Late on Friday night, Jonny Durand Jnr and Brenden Sadgrove showed up at Steve Blenkinsop's house in Adelaide, South Australia, in the Red Bull Land Rover Defender pulling the trailer which contains a Moyes Bailey Dragonfly.  They had driven for fourteen hours from Forbes, NSW, Australia, where they picked up the trailer, on their way to Eucla, Western Australia.  The great adventure to set new world records for out and return speed (and perhaps distance) had begun.

January 18, 2104

Jonny and Brenden drove 700+ km to Penong just west of Ceduna to stop for a visit with old time hang glider pilot, Drew Cooper.

January 19, 2014

Jonny and Brenden arrived in Eucla, about seven kilometers into Western Australia on the Eyre Highway (A1). Eucla, population maybe now about 40, is 500 km west of Ceduna and 700 km east of Norseman, the closest places with any population along the highway.  They quickly got to know most of the folks in town (who all seemed to work for the hotel).

This is our headquarters for the next two weeks as we help Jonny set the new 100 km, 200 km, 300 km, 400 km (no record yet) speed records for out and return flights, distance record for declared and free out and return.
