简介

The EPIC 2 is very safe and reassuring, accessible to low-airtime pilots but with handling and performance that experienced pilots will love.

We’ve improved the launch behaviour – the wing comes up smoothly and easily without overshooting. In flight, it’s slightly faster than its predecessor (+1km/h at trim, +3km/h top speed) and has improved glide. It’s also a great climber, especially in weak lift.

Long brake travel means you won’t accidentally stall or spin, but it is precise on the brakes with direct, playful handling. The EPIC 2 is safe and reassuring in strong air, but does not hide the bumps. At BGD we think feedback is really important: the wing tells the pilot about the conditions, and the pilot can anticipate and avoid collapses.

Like on the BASE 2, the new EPIC 2 risers have a B/C steering system for piloting the wing while pushing the bar and flying at speed.

科技

B/C Speed Riser

The risers are equipped with a new ‘speed riser’. It attaches the back of the speed system to front of the C-line steering handle. This balances the load on the C-steering handle, making the C-steering system simple and light to use. Because the force is on the dimensionally stable Kevlar-reInforced riser and not the pulley, the glider stays in trim.

千万级迭代流体/结构分析

滑翔伞设计的未来在很大程度上取决于模拟。不用再一个一个设计并生产雏形伞,现在,我们采用特别研发的结构/空气仿真程序,可以准确模拟出数以百计的伞。实际上,我们现在可以使用该程序测试虚拟的设计雏形,我们的每一款伞,现在都能实现200多次的模拟雏形,相关分析涉及多达5000万次的结构/空气迭代计算。

波浪形前缘剪切(CCB)

波浪形前缘剪切技术被用来改善伞的形状摩擦,提升伞的稳定性及整体综合性能。上翼面前端这两条延翼弦方向的缝合,能够很好地适应伞充气时因“球面效应”而产生的表面“鼓起”。平板缝合的气室在满足翼形时,这种“鼓起”会在翼肋处需要高达5cm的多余布料。波浪形前缘剪切技术利用3D塑形,巧妙吸收掉多余布料,极大地减少翼肋缝合处的褶皱,有效提升翼肋翼形及稳定性。

渐进式的稳定性

我们设计的伞全部都采用渐进式的稳定性,帮助飞行员及时感知颠簸并避开。这让飞行变得更加安全、更加舒适。

最优的伞绳分布

多年来,我们用来优化伞绳分布的设计系统已几近完美。我们使用大量的数学工程,程序软件,以及简单而传统的“猜测并检验”的方法来构建伞绳分布。结果简单明了:更少的伞绳,更坚固且更快的伞。

让人眼界大开的安全性

会“交流”的伞更安全。更安全的伞会让飞行员表现更好。表现更好的飞行员会飞得更远。飞得更远的飞行员会更开心。因此,让人大开眼界的安全性能够让飞行员们更开心。

快速磁锁

快速磁锁是轻松连接刹车和组带的一个轻质而紧凑的附件。内部锁定系统和小磁块一起将刹车手柄在各个方向都锁定住,除了往下朝向飞行员的方向。这个独特的设计意味着在地面控伞、叠伞或练习科目时,刹车手柄都不易脱落。快速磁锁系统为飞行员轻松化解按扣和磁铁所带来的诸多烦恼。

三指对角支撑

横穿整个翼面的弦长,我们设计了穿过翼肋孔的三片式对角支撑。这一设计能够避免布料从翼肋上发生偏斜,即使在拉刹车时伞也更加坚固,从而让伞拥有更高的结构整体性。这一点在伞的后缘上显得尤其重要,因为后缘的翼形更薄,较浅的对角支撑结构承受着更高的载荷。

双层前缘

前缘的下翼面在紧挨进气口的位置向内翻折,形成双层结构。这一结构通过伞的内压从后往前被充气,让伞拥有更干净、更稳定的前缘结构。

Single Shark Plastic

The EPIC 2 is the first wing where we have used a single strand of plastic reinforcement wire for the leading edge, instead of two pieces. It reduces weight, simplifies the design and maintains a solid leading edge improving launch and giving a longer brake range.

Multi-Plastics

By using different sizes of stiff black Perlon® and flexible orange plastic in specific places, we have optimised the rigidity and softness of the wing along the span to achieve optimal progressive stability.

多重聚合刹车系统

错综复杂的刹车系统同时采用对称和非对称的收帆聚合方式,让伞的操控感十分锐利,并且让后缘整洁干净。

目标群体

A safe, fun wing that’s a joy to fly. We’ve improved the performance while maximising safety, and the EPIC 2 is a versatile wing. It’s perfect for first cross-countries or a go-anywhere glider for weekend pilots. And, like the original Epic, it’s a great tool for getting to grips with your first freestyle moves. The test team can confirm it’s loads of fun for wingovers, SATs, heli’s and the like.


设计师笔记

The EPIC has been a very successful Low B wing. It was important to us to keep the accessibility and handling it was known and loved for, while improving performance. It has great glide and climbing ability, and a bit more speed than the original.

While it might look quite similar at a glance, design-wise a lot has changed. It now has 45 cells and an aspect ratio of 5.2, both slightly higher than on the original EPIC. The internal supporting structure is more intricate, but despite all this the glider weighs the same, 4.9kg for the M. The riser set is new, and the lines are a mixture of unsheathed higher up, and sheathed at the bottom.

The Epic 2 has short rods in the leading edge and none in the trailing edge, so it is easy to pack. The single-piece leading edge plastics are made of different materials: stiffer purlin in the central section with softer, more flexible supports towards the tips. It’s a light, elegant and effective method for shaping the leading edge.

As on the BASE 2 and CURE 2, there is a double skin on the lower surface of the leading edge. The internal pressure of the wing pushes on this lower skin which helps pressure it to maintain a clean and stable leading edge.
