Designer and CEO Gin Seok Song explains the development of the Explorer 2:
“Squeezing something extra from the original Explorer was not an easy task! Rather than try to increase performance by increasing the aspect ratio, we decided to go the other way and play with the surface area. Smaller and smaller wings might be today’s trend, but all things equal, larger wings offer several advantages. With the increased Reynolds number, they not only perform better but are also more stable.
The key was to increase the surface area without compromising responsiveness and speed. To do this, we drew heavily on the wind tunnel research we are carrying out in partnership with a university here in Korea. This is a major project that has already produced some insights that are trickling down into production wings. This work helped a lot to optimise the sail tensioning, which for the pilot means improved climbing and more refined handling.
In addition, we have a new smart riser with C control system. There’s a toggle for easy control and an additional pulley for extra smooth operation. With an extra 2cm of accelerator travel, we were also able to increase maximum speed. It’s a real pleasure to fly on the bar. For the reinforcements, we are also using a combination of a new type of plastic rod and Nitinol wire. The Atlas rods are used in critical nose sections due to their high resistance to breaking, dimensional stability and minimal wear and tear effect. The Nitinol wire on the top surface towards the rear perfectly and precisely supports the trailing edge whilst reducing weight and packing volume.
All in all, the original Explorer was a firm favourite with a wide range of pilots. We are confident that the Explorer 2 has even more to offer an even wider range of pilots.”
- Strategic mix of new formula plastic rods and Nitinol (Nickel titanium) wire for dimensional stability, performance and more compact packing
- 3 risers / 3 lines spanwise
- Unsheathed aramid lines with optimized diameters
- Speed system with C riser steering
- Gathering (reefing) system and mini ribs on the trailing edge
