Airwave Gliders Sport

Sport 4


When the original Sport was released it had a DHV1-2 certification, with DHV2 performance. The Sport 2 was planned to reduce the weight of the glider, increase the resistance to collapse, increase stability accelerated., and reduce the pitching (dynamic) of the wing so the glider is easier to fly. An important consideration was to keep the DHV1-2 certification.


The aerodynamic profile of the wing has been selected to give a glider that is not too pitchy, yet still bites nicely into thermals. In roll the glider responds smoothly to weight shift yet it remains reassuring. This balance of stability has been obtained by using new technology unique to the Sport, called the Stability Control System.


The new internal structure of the Sport is both lighter and more structurally rigid. But this rigidity is carefully balanced to be rigid where it helps to be rigid and to be soft and flexible where this helps the overall feel of the wing. The new internal structure is very complex, and is composed of 224 internal structural members. Each of these members is a piece of cloth which has been carefully designed using CAD techniques to support the wing giving a clean profile whilst minimising the weight of material used to create the structure.

The line layout of the wing has been optimised compared to the original Sport so as to reduce the ovverall amount of line parasitic drag while maintaining launch characteristics as well as reducing the likelihood of cravates by careful positioning of the line bifurcations.


Comparative glide performance tests showed that the glide performance at trim speed was significantly better than the Sport1. Factory measurements show that the best glide of the Sport1 is 8.2, and the Sport2 glides at 8.5. The difference in glide performance increases with speed. The Sport2 is not faster than the Sport1.


The Sport2 has passed new DHV1-2 tests, which include much tighter controls on asymmetric collapses as well as spiral stability, pitching and dynamics. The new requirements are that a DHV1-2 must limit glider pitching to less than 45degrees following a 75% side collapse.


The DHV 1-2 Sport3 is directly evolved from the Sport 2 and designed by Bruce Goldsmith is certified in 5 sizes, with a complete sail redesign with hybrid Sail technology (longer lasting and lighter).

Airwave Sport 3


The Sport 3 uses 50gm/sq m silicone coated Gelvenor on the leading edge, and for less stressed parts of the sail, 35gm/sq m Porcher Marine. Two different weights of cloth are used for the supported and unsupported ribs, providing strength where it is required, and using lighter cloth elsewhere.


The whole sail of the Sport3 has been completely redesigned over the Sport 2 using the paracad software, giving less drag. The openings now include curved panels on the bottom surface and are finished with soft tape giving smoother reinflation. According to the manufacturer, the Sport3 also offers “auto-centering” in thermals thanks to the balance between the pitching moment of the profile and the wing twist. The Sport 3 was available in 5 sizes.


Research on the Sport4 involved building both 3-line and 4-line versions of the Sport4, both of which would pass the certification tests. After extensive testing it was apparent that the 4-line version was simply easier to fly: it thermalled better, with longer brake travel, and still had responsive handling.


The conclusion was that for gliders of longer cord 4 rows of lines were better, so for the Sport4 we used four rows of lines in the middle of the wing where the cord is longer and 3 rows in the tip where the cord is less.


The wing incorporates hybrid diagonals, span-wise strengtheners to add greater rigidity and collapse resistance, and one less of the cells, to give even greater roll stability and make the wing even more accessible to a greater range of pilot. The X-Brace of the FR series is used on the Sport 4. This single X of reinforcing webbing in the middle of the wing gives a centrally reinforced region of stiffness and creates a stronger, more collapse resistant wing.


The Sport Competition optimised the glider though several changes to the wing's construction that has improved the flying experience in almost every respect, from performance to weight handling and safety. Flight test measurements revealed a glide improvement at trim speed, but a massive improvement of around one point in glide at top speed, leading to a significantly flattened polar curve.


The Sport Competition has been optimized by changes in several significant construction details leading to a weight reduction of almost one kilo.


By using the lighter materials the brake pressure has been reduced and the handling has improved as well due to the reduced inertia of the wing. The Sport Competition is certified EN-B and LTF 1-2.


The Sport Competition uses a lighter cloth on the bottom sail as well as in the internal structure.The gallery lines of the Sport Competition use 80kg UV coated microlines by Edelrid. It is only the lines next to the wing that are microlines. All the middle and lower lines are wear resistant sheathed lines. The parasitic drag is reduced even more by using special risers.


The change in the speed system the Sport Competition gives a smoother more direct acceleration.
