Most striking are two wings with symmetrical profiles, the stabilizers, on the side of the hull which is very slim and aerodynamic. The stabilizers are arranged in a V- shape at a 33° angle to the hull, with a 250 L water tank at the tip of each for water- ballast. Those tanks can be filled within a few seconds through a system known from firefighter planes. During maneuvers the water is routed from the leeward to the windward side through a pipe system.
Another feature to increase control over the vessel at high speeds is the Canard Wing on the bow, like on a fighter jet. Through this wing, the pilot can control the longitudinal axis of the vessel. In that way, the forces typically resulting in a nose- dive, are controlled and can be counteracted.
In order to reduce drag, the V_REX is equipped with hydrofoils, lifting it off the water surface. The centerboard- hydrofoil is 3.8 m high, whereas the stern- hydrofoil, which is also the rudder, is 4.0 m high. The height difference is important for the rudder not to be situated in the turbulence of the centerboard. The hydrofoils are designed so that the V_REX has a safe “flight above waves”.
In fact, the design of the hydrofoils is inspired by one of the fastest fish, the Indo- Pacific Sailfish, which reaches up to 120 kph!
The boat is helmed by two persons in a monocoque at the center of the stabilizers, known from airplanes and Formula1 cars. The helm moves the rudder by using two pedals, one to starboard, one to port. The crew is seated behind the pilot adjusting the 40 sqm sails, a battened mainsail and a jib, as well as the system for the water- ballast.
After finishing outer skin now we are into making the core and inner skin. Absolute high tech and light weight.
Also hydraulic cylinders are ready developed and started manufacturing.
SENSORIC & HELMINGTOOLS
Already selected some hardware parts and thinking of Backhoff-System which is used by Emirates Team NZ.
STILL LOT TO DO - BUT ALSO VERY MUCH EXITING!
In the category of CREATIV-INNOVATION V_REX is already voted in the 2nd level of the so called "EDISON-PREIS!".
This trophy will be granted only to the innovative and creative start-ups in Austria.
After starting the this years Edison-Preis only 22 companies reached the 2nd step. Splited in 3 categories V_REX do have pretty good chances to reach a trophy of this very well known challenge.
Meanwhile negative moulding is in progress and now we are absolute confident, that the initial tests of V_REX can be done within 2020.
All the very best and GODSPEED!
Hull design finished!
The hull design is finished today and ready for CNC moulding.
We are close to our next mile stone once the first time a CNC milling machine will start working on the V_REX.
V_REX will be made out of full carbon fibre and in the best quality available in the international market.
V_REX an outstanding concept becomes reality!
Of course initially you have an idea, how sailing could be more efficient, faster, easier to handle and safer. A sailing boat, which turns the sailing concept up side down. Doing scientifically tests, showing the soft proof of the concept. Not enough and still a long way to the first prototype:
- Naval engineering
- Structural engineering and
- System engineering AND
- do not forget the financial issue! :-)
... which makes than out of an idea and some sketches a real working design.
Now, we are close to realize the prototype and soon the first CNC will start working on our idea.
On the left hand side you see the development only of our bow which should have different purposes.
a) extend the waterline in order to be faster in displacement mode
b) be sharp and aerodynamical, once V_REX is airborne and therefore not to cause turbulences.
c) in case of a so called "Nose-Dive" develop some uplift through out of its upper shape.
d) the retractable bow will also work as an collision bulkhead.
e) throughout the retractable design, it will generate access to the Canard-Wing actuators for maintenance.
f) and of course there is a fitting where you can simply fix your bow line.
This is just one example of one of our very simply pieces on the V_REX.
