XLP2 (Xtra Large) Wing
XLP 2 "Xtra Large Program" Kitefoil Wing
the all-purpose wing
Level: From novice to expert
Suitable for: Cruising, Freeride, Ultra light wind
Area: 682 cm²
Wingspan: 67 cm
The XLP2 belongs in every rider's foil quiver. Above all the XLP2 is the ultimate wing for ultra light wind foiling, and its ability to fly very slowly thanks to the Alpinefoil VAS (Variable Angle System) also makes it ideal for beginners and learning. With a very pronounced curvature, and arrow-like shape, the XLP2 is extremely stable and easy to fly over its very extensive speed range. Its versatility of the XLP2 allows the rider to foil from the very lightest winds (down to 4-5 knots), and also to reach top speeds of 26-28 knots when under the feet of experienced riders.
AlpineFoil Kitefoil wing technologies:
MCF (Monobloc Continuous Carbon Fiber)
Now present in all our carbon products, MCF construction provides an exceptionally high strength and rigidity. With MCF we mate the two halves of the wing with filament winding, thus eliminating the traditional glue joint. We get a seal without any weak point, with an elongation factor of 1.6 to 1.9% compared to about 40% elongation for a glue joint.
AlpineFoil mounting system
The 4 mounting holes are staggered to best support the connection of the wing to the fuselage, ensuring the rigidity and cohesion of the whole system. Screw heads are countersunk to fit snugly in the wing, reducing friction and improving glide. This system now standard on all Alpinefoil wings and allows full compatibility with all our existing and future foils, including Alpinefoil 4.0, Alpinefoil 4.5, Alpinefoil 5.0 Full Carbon, Alpinefoil Access 5.0, and Access 5.0 Alpinefoil V2.
"Arrow" swept wing shape
All of our foil wings are designed with a swept wing angle, more or less pronounced depending on the type of wing. This swept wing design is extremely important for stability. These complex shapes require 30% more carbon fiber in the manufacturing of our wings compared to a right-angle wing.
The dihedral curvature of all our wings is designed and developed in a digital wind tunnel. This curvature is one of the most important parameters in the design of a kitefoil wing. The principle is simple: a curved wing will have bearing vectors that intersect at a point, radically improving the stability compared to that of a flat wing where none of the vectors intersect. The dihedral curvature also greatly affects the lift and stability of the wing. A curved wing reduces parasitic roll, stabilizing the wing's trajectory and thus increases steering precision. The curvature also helps to maintain lift and reduce the tendency of a foil to "hunt".
VAS (Variable Angle foil System)
All Alpinefoil wings are designed with a dynamic load profile between the center of the wing and the wing tip. This unique Alpinefoil feature uses a high lift wing tip providing the lift you need at low speed, resulting in better control and extraordinary stability. With an increase in speed (and thus a decrease in incidence), this effect gradually fades to decrease the wing load and refocus the lift, allowing the wing to achieve higher speeds while remaining extremely stable. This results in greater speed range and a very progressive stall.
