简介

Dual是通过EN-B安全证证的双人滑翔伞,负载为120-250kg,平面面积为40m²,涵盖了绝大部份的动力双人伞飞行员连乘客的总负载。为了安全,我们绝对不建议在负载范围以外进行飞行活动。我们相信平滑的前缘设计可以增加滑翔伞的稳定性,因此我们将波浪形前缘设计(CCB)科技,融入到Dual的设计之中。最佳化的双人伞速度调节器,可以让飞行员在不同负载或天气状况下,调较攻角令可用速度更多,以应付不同的飞行状况。

设计特点

Progressive stability

Progressive stability has been designed into all our gliders to help pilots feel turbulence and avoid it. This makes for safer and more comfortable flying.

Cord cut billow (CCB)

Cord Cut Billow technology has been developed to improve the form friction, glider stability and overall performance of our paragliders. Two seams run chord-wise across the top panels of the leading edge to accommodate the panel ballooning that happens when the wing is inflated. Up to five centimetres of excess material is created on the sides of an inflated flat panel bending over a wing profile. Cord Cut Billow technology absorbs the material with a 3D panel resulting in fewer ripples and improved rib profile shape and stability.

Replaceable trimmers

Committed to building products that last, we only use durable high-tech fabrics and sheathed kevlar lines on the Dual 2. In addition, we’ve created a replaceable trimmer system for the Dual 2 to maximize longevity.

Optimised line layout

Over the years we have perfected our system of optimising the line layout of our wings. We use numerous equations, software, and the plain old guess-and-check method to build our line layouts. The result is simple: fewer lines making stronger, faster gliders.

Eyes wide-open safety

Gliders that talk are safer. Safer gliders make pilots perform better. Better performing pilots fly further. Further flying pilots are happier pilots. Eyes Wide-open Safety produces happier pilots.

目标群体

Dual凭着《分享天空,分享快乐》的精神研发,适合动力双人伞飞行员,让乘客享受在天空自由自在飞翔的感觉。言语笔墨难以形容在天上自由自在飞翔的感觉,Dual可以让你跟家人和朋友分享遨翔天际的喜悦。经验丰富的BGD设计师,令Dual的操控感极度接近单人伞爽快的操控感觉,让飞行员可以更轻易进行起飞和降落操作。


金匠笔记

我过住多年进行双人伞飞行盘旋热气流经验之中,没有一只双人伞给予我足够控制量的感觉。我认为原因是因为双人伞相比单人伞储蓄了更大的能量,以及拥有过高的惯性,因为巡航速度高,导致刹车和转向迟钝,需要更多力气才能进行操作。但是我的手没有足够力量去随心所欲控制双人伞。

我并不想增强手部力量而做健身,因此在设计Dual时,令刹车拥有单人伞的灵敏,让飞行员可以像单人伞般,随心所欲地操作,轻松进行起飞丶转向丶降低丶甚至进行花式动作等等...

在设计Dual的时候,BGD研发团队花了大量时间,研究并改良Dual在起飞和降落的特性。Dual拥有温和渐进式的充气过程,飞行员有充裕时间因应不同风向地形修正滑翔伞,而且Dual会自动在充气完成後,在头顶位置自己停下来,在风和日丽天气,双人伞飞行员特别喜欢Dual的特性。
