目标群

Remember that feeling, the first time your feet leave the ground and you are soaring, feet in the clouds, viewing the world from a different perspective? If you could bottle that feeling and share it around … that’s what the DUAL 2 is for – sharing the joy of flight! A clean take-off is absolutely critical to a safe and successful tandem flight. The DUAL 2 takes the load quickly and the short run required is a huge step forward for passenger safety. We’ve made the Dual 2 in two sizes: the 42m² will suit most, and the 37m² is for all-up weights below 200kg.

形容

The DUAL 2 is an entirely new design. It took us years of development and many prototypes to perfect, but we believe it is a significant leap forward from the original Dual, which itself was a benchmark EN-B tandem. It’s a pleasure to launch and to fly, with light, intuitive BGD handling and an outstanding sink rate, making it a 'top of the stack' performer. Big ears are effective and easy to use, and we’ve added a new big-ears locking system. We know commercial pilots need tandems that last well so we’ve made the DUAL 2 robust and strong, with durable cloth throughout and all-sheathed Kevlar lines. The trimmers have easy-grab plastic balls and easy to replace webbing.

Bruce的备忘

With this project I wanted to make a tandem that is ridiculously easy to launch as not all passengers are willing runners, but I didn’t want to sacrifice that light and sensitive handling that was so highly praised in the original DUAL. To achieve this we designed a whole new single plastic shark nose just for this wing. In the air the handling is a delight and thermalling is outstanding. The whole team are very happy with the outcome. It’s a pleasure to fly, and a dream to launch: two steps and away!

设计特点

让人大开眼界的安全性

会“说话”的翅膀更安全。更安全的伞让飞行员表现更好。表现更好的飞行员飞得更远。飞得更远的飞行员更开心。所以,PUNK让人大开眼界的安全性会让飞行员更加开心。

Progressive Stability

Designed to warn pilots of light-to-moderate turbulence, rather than suddenly collapsing when things get really unruly. Bruce’s article in Cross Country magazine, ‘Shifting Our Thinking on Safety’, explains how, “A wing that is super stable and almost never collapses can lead to more accidents, because when it does collapse the pilot is not prepared and has little experience of how to deal with the situation”. Any wing will collapse given enough turbulence. A small deflation in medium turbulence is easier to deal with, and therefore safer, than a big collapse in strong turbulence.

Cord Cut Billow (CCB)

Shaped panels in the leading edge reduce creasing along the ribs. The creases are more pronounced on larger cells, and CCB technology therefore makes a bigger difference to gliders with bigger cells .

精心打造的翼形

我们使用最前沿的软件技术,来保证在尽可能多地移除非承重材料的同时,保持伞的强度和刚性。这让伞变得更加轻盈,既不增加多余的成本,又丝毫不降低整体的强度。穿孔的定位和大小主要取决于伞翼面的局部受力,这只有通过最新的软件技术革新来实现。

Post C Band

We have added a ‘Post C' band running along the top surface which seamlessly moves down to the bottom surface at the tip connecting directly to the last line cascade. Instead of putting heavy plastic rods above the C lines we use this band to counter the common flip up ripple caused when adding a little brake. The problem with paragliders is when a little brake is applied the cupping of the trailing edge creates lift which often buckles the profile near the C’s. We have solved this problem with the “Post C Band” an eloquent, lightweight, clean, and volume-reducing solution.

小A组带

PUNK上的“大耳朵”专用小A组带,大小是A组组带的1/2。这有助于在踩加速并使用“大耳朵”时保证速度和稳定性。加速系统轻质简单,在加速时也保证优良的滑行性能。

三指对角支撑

横穿整个翼面弦长,我们设计了穿过翼肋孔的三片式对角支撑。通过避免翼肋上的布料偏差,并让伞翼在刹车输入时更加坚固,这一设计确保了伞翼拥有更高的结构整体性。在伞翼后缘这一点显得尤其重要,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。

最优化无支撑气室

优化的无支撑气室群专为受伞绳布局影响的翼展方向上的载荷分布而设计。通过强韧的内部结构,引起更多翼展方向张力的伞绳布局,来支撑更多的无支撑气室群。在伞的内在品质保持不变的前提下,这有助于减少总伞绳消耗,从而减小阻力提升飞行性能。

迅速磁锁

迅速磁锁可以将把刹车手快速连系回,有锁定机构,确保刹车把手不会因为意外而脱出

低伞绳用量

本着多年伞具设计经验,综合电脑软件,以及现代方程式,发现使用更少伞绳令伞体更强更快,而且有效提升性能

低伞绳用量
Single Plastic Shark Nose

Results in a very easy launch with minimal running required, without increasing the brake pressure.

Big Ears Blocker

A cam cleat system that allows the pilot to pull big ears on, in the size required, and then lock them in place. A neoprene cover prevents lines from unintentionally catching in the system, and the ears are easy to release.

Trimmers

Trimmers have 10cm travel and a plastic puller ball on the end to make them easier to operate. Trimmer webbing wears, but is easily replaceable by untying a knot inside the puller ball. A spare set of webbings are delivered with the glider.
