Summary of the hydrofoils R&D

Hydrofoils R&D 2015 update
after successful TFW and some good sessions on the lake, plus a lot of time
on the comp and in workshop, here the summary of the work!

Y foil
As already posted the Y Moth sail ruder hydrofoil!
Status, vertical mold ALU done, foil on testing!

AHfoils

The Classic kite hydrofoil done for the AHcustoms.ch
The hydrofoil with great potential for super low take of and great gliding suport
true the jibes and free riding. The set up and construction allow the modifications to
the race setup too!

Precision of the CNC molds

 

 General look

 

"O"wing

And not the last one, as was predicted here the "O"wing concept kite hydrofoil.
Out there in the aeronautic circles they are different names of this kind of wing set up!
From the box wing, circle wing, elliptical wing, closed wing, joined wing all of them are use the same
idea to drop down as much as possible wingtip vortex!
The working name Owing was chosen as the shape run continues all around!

With three new hydrofoils in this period I am happy to complete the work.
T "Y" and the Owing are booth into the testing period, more of the conclusions later on!

Stay tuned

The foiling week Garda 2015

Mahalo,
right back from Garda lake, complete some photos and

or here TFW 2015

As the last year TFW is the best meet of the foiling boats from all around the world.
Good organization from Domenico, Luka and the rest of TFW team. For any R&D,
design or manufacturing people, it is priceless to be there. All the right power people are
coming together, have discussions, the forum run and it is much more to see on the water!
So do not miss this event in the future!

Amac was presented the new Waszp, the people foiler, so this is now official ;-)
Good work done Andrew!

The ahcustoms.ch kite hydrofoil was there, well accepted from foil community!

Well for this year we have with us the Old-timer as well. 10years of foiling or living museum
as we have jokes in foil community! The axeman7 moth sill on foils, well we broke the push road
on the main foil, so we was on the water only for two days. Oldy survive and crew also and
this is important!

White bear cat, Luc is assisting and help to crew!

Three type of today foiling boats,
Moth, Laser and FF, the kite foil is missing!

The SLO 4201 Luka Tomori doing well for the firt time on the event!

 Next year generation of foilers ;-)

Ota preparing the boat for the lake trials!

In all, Garda lake, TFW we are coming back for next year,
not for holidays, with new stuff, new ideas, new products!

The internet galaxy & hydrofoils

Mahalo readers,
Not I am lazy, but simply no time on the running projects to be really accurate here and write
daily/weekly the news on the blog! Some of people are simply better on CAD and in workshops
at R&D, some of them are writers and good on social media pages.

Lets make some update on kitefoils under R&D.
It is true the post on Kite forum push me to write here again
http://www.kiteforum.com/viewtopic.php?p=879622#p879622

Where the community found from Christmas card the Owing kite foil. Really happy to see some
of the people have really sharp eye on new products.

For me not new foil, the Owing was presented at TFW on Garda lake last summer
http://drlojz.blogspot.com/2014/07/the-foiling-week-garda-lake-2014.html
Where all the big minds of foiling world come together, to present and interchange the work, ideas etc.

At the moment the molds for "classic hydrofoil" are ready in production, I will post here the finished product!
The kitefoil is developed  for the www.ahcustoms.ch from Swiss!

 Main Crossover AH-foil wing mold

 Body mold finished

 Vertical half of the mold

 The negative V tail

Here some early comp graphic from last year! The Owing is under development and before summer is in plane to hit the water ;-)

Lets move the product to be simply as possible!

The Foiling Week Garda lake 2014

Mahalo,
just come back from Garda lake, where we was with Ota visit the TFW 2014.
More about here http://www.foilingweek.com.

It was great event and all respect to Italian team of enthusiasts to bring the TFW to alive.
To be there was some how the privilege with respect to the world power people
on foils, with foils, for foils! We have chance to listen the conference and free talk to great minds
of hydrofoiling as James Grogono, Andrew McDougall, Martin Fischer, Thomas Jundt,
Tom Speer, Edoardo Bianchi, Phil Stevenson.
 

The short picture report can be find
https://plus.google.com/photos/111689916731696792459/albums/6035082551691076273
 

We saw different designs, different boats, some of them was possible to test
and what is more important  is we share ideas,
the visions of the coming 3rd dimension on the water.

TFW, we are coming again, hope for next year, not only with the camera, with the boat,
foils, wings, lets go for it!

14 Years

What a coincidence,

when I agreed to test the new Hydrofoil board, I did not even have the idea that I will meet a 14 years old kite surf  board, which was produces by me in 2000, completely up to date for that time.
There is 14 years of development in the area of ​​kite products.

Newbie meets the oldie, nice feel and they looks great together ;-)

  

 

Some successful board test was made ​​later and here it is the photo documentation. Looks well an it is good to see the Hydrofoil driven by the young power! Yari do his job well and we are all waiting for the next stage of R & D! Test was made in cooperation with http://www.kitelife.si and http://keka.si/ driven by mr. Boris Stepanov! Thanks guys!

Wait and see this place for additional info on the new foils, the development is going to Switzerland

 and yes into the workshop are the CrossOver foils for http://www.ahcustoms.ch  ;-)

Hydrofoil 2014 part II

Mahalo,
as some request was written on Kiteforum, section Hydrofoil
http://www.kiteforum.com/viewtopic.php?f=196&t=2384836
like @drLihgtWind find the Stelth race board from the past is used
to test new foils creation. Nice comment good observation ;-)

@ windfreak74 was asking for more specifications of the hydrofoil,
lets make some points clear first.

As I wrote already the foil is made out of Moth hydrofoil molds with shorter span of 500mm
and the cord of 110mm. At the hydrofoils we have on the first place two well known problems!
Ventilation and cavitation, as the ventilation occur when the air from above the water line is drawn
and cavitation occurred when the water pressure around the foil come to the point of boiling.
More about this stages here
http://www.powerboat-training.co.uk/articles/articles-propellers-ventilation,%20cavitation.htm
http://www.propellerhub.com/cavitation-and-ventilation.html

The reason to have the curved mast to front is to avoid the possible ventilation,
this is one point the second is pointed angle forward  in vertical axis by Yaw movement give us
some positive Pitch movement, not to draw the nose down!

-The tail must to be out of turbulence of the stunt and wings
-Why Inverted V tail? On the whole hydrofoil geometry we need the same flying surfaces as on the airplane.
Wings, tail, rudder! The V-tail is lighter, has less wetted surface area, and thus produces less drag.
Inverted V tail geometry is in this construction well out of the turbulence of wings and body of hydrofoil.
http://en.wikipedia.org/wiki/V-tail
http://salempress.com/store/samples/encyclopedia_of_flight/encyclopedia_of_flight_tail.htm

-General length from wing to tail 500-600mm


Some more ideas and work already on the desk and the cad screen,
lets see whats come out of this pot!
