Mahalo foil & vortex lovers
following bionic and physics rules to achieve totally new concept of hydrofoils!
Well known as round wing, closed wing, circular wing, ellipse wing, etc
(ask uncle google or search true academic circles!)

On drLojz lab table for years, time to show the new stage of R&D.
First touch on water, looks promising as we respect over know-how
with no surprise. Everything work as simulations shows!

With good mix of bionic design and understanding of principal physics,
connected with additive prototyping and help of carbon fibers
the new Owing2019 is here!

Owing will be with dr Lojz on the coming
TFW foiling week on Garda lake!
https://www.facebook.com/foilingweek
See you there with any needs, questions or suggestions.

Contact me on to meet there,
or drop a meesage to drlojz2(at)gmail.com

Key word, the future is bright without vortex :-)

stay tuned

TFW foiling week 2017

Mahalo,

"Be there or not to be",
Meet Don Montagure my old friend, priceless!
Jetfoiler works well, presentation was cool, almost in
the dark! To be part of the Jetfoiler team, kudos!
Two days only with full soul and foils!

Moth Euro Cup 2017 Portoroz

Mahalo,
Moth Euro Cup 2017 on Saturday, the view of regatta from Jury boat, I was not on my Moth for this year! Next time for sure! Official report from JK Pirat http://www.klub-pirat.si/dogodki/koncano-drugo-dejanje-letosnje-serije-eurocup-za-moth

TFW Garda

The foiling week Garda Lake 2016
In all the festival of the best foilers of the world! I was there the third year
in a row and it was great! At the TFW we meet the constructors, designers
and sailors on and with the hydrofoils!

For this year the event was even bigger and more and more foilers are coming!
We see, the big CG32 cats, the Flying Phantoms, Moths, Kitfoiles, Windfoilers, S9 Bimare
and a lot of prototypes, like the Voilavion, Orca H-15 and a lot more! Orca is funded and conceived
by Veneri, will be marketed by Veneri once development is completed. The design is by
Giovanni Galeotti and Tristan Mathez Loic (Tris Design). Décision has built the prototype.

The oldest, 25 years old foiler was the Hobbie Trifoiler still in action!

Regattas was true the classes and mixed in categories!
The gallery true my lenses:

The next generation of the foilers ;-)

25 y old, respect!

35 knots + no comments

Windsurf foiler

WASZP

For this time the Andrew McDougall, well known Moth guru, present the new WASZP
the entry level foiler! Adriano was organizing with the team the lake trials! Up to 20 sailors was
daily testing the WASZP to get the feel, what is all about! Everybody was coming back
on shore with the smile! I was on the water twice and the WASZP is just beautifully small foiler!
Thanks to Andrew and Adriano to give me the chance to sail WASZP, it was nice and I love it!

Dr Lojz on the WASZP, thanks to Luka for the shot ;-)

A lot of friends was there, for this year I was alone, Luc and Ota was on parallel activities,
I miss the representative from DADA agency, but will be better in the future, for next year
I looking to have new foiler ready, just to know ;-) Be there => Priceless

Go and enjoy the nature, wind, speed and pure life of the soul!

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!

From the shadow

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

Y hydrofoils

Mahalo,
as I mention in previous post, the work is done on Y hydrofoil.
It was planed to have finished the foils to TFW at Garda lake,
but was not on priority list :-(

Well I can proudly present the completely new R&D on the Y hydrofoils.
On this project two parallel activities come together. First is I have constructed
and ordered the ALU vertical mold for autoclave technology. This shape can be
used for kite foil vertical or for the Moth boat! Maybe for some future development
on the foiling boats! Game is open. The mold is 1400mm long, tapered from
120 to 100mm with parallel section of 300mm on the top! The the weary first piece
it was made by Albatross-fly company based in region! More about company
here http://www.radolca.si/en/albatross-fly/
and the web page
http://www.albatross-fly.si/proizvodnja.htm#
They are simply the best, we know each other for decades and the foils was made strait
into this "cook pot"

Of course autoclave technology and the result is outstanding.
Big thanks for this suport to Albatros-fly company!

To this vertical I was add the Y hydrofoils! There are at leat two reasons,
one is to avoid the cutting the water surface, the second is to spread the forces
just like V tail on airplanes but in negative direction! Anhedral shape again like
I am using on the tail for kite hydrofoil
http://drlojz.blogspot.com/2015/03/the-internet-galaxy.html

I am sure this set up ca also better handle the flutter on the hydrofoils,
see the post  http://drlojz.blogspot.com/2015/08/wing-flutter-hydrofoils-flutter.html
while the negative V ir Y shape of the wings will spread the forces differently.
So no flutter anymore or at least later at higher speeds!

So if we see this photo on http://sailinganarchy.com/
with the question "what is it?" I am not surprised! Free minds go forward,
it will never stop!

 

This photos was made on rainy afternoon on local lake Bled, just after the maiden
fly was made. as usual unlucky with the wind, but enough to prove the take off
in 8knots and stable fly. All I can say at the moment, the Y hydrofoil works at
least good as old normal one! more testing and when the weather go better!

 

  

 So much at the moment!

Wing flutter & Hydrofoils flutter

Mahalo,
I was just watching the the US nationals regatta in Moth class and in this video
https://vimeo.com/136467586
at the 04:30 + the whole foil set up come in the flutter
OR
maybe I am wrong and this is just the sampling of the video
(hope yes) otherwise I can only imagine the sound and the vibration :-(

We all know how hard are the Moth foils build, almost unbreakable and
to see the flutter like this O la la! I hope everything was gong well there!

I know flutter is not common on Mach2 boats, here I can not judge if this foils are "home build"
but it is interesting to see!

My answer to this problem are Y foils!
