The aspect ratio of a glider is not the only factor in passive safety, but still a very important one. For this reason our wings have the aspect ratio they require. Our design motto is as much as necessary, as little as possible.
所有NOVA伞都崇尚简单实用。您可以使用长条袋来叠伞,但这并不是必要的。我们对进气口支撑结构有丰富的经验,我们发现,叠伞的方式对伞具的耐用性实际上影响很小,可弯折的伞头结构支撑可以很快恢复原形。
不同于简单的一整条布料,这些对角翼肋由多条布料制成,并根据布料的抗撕裂线方向定向切割。虽然制作过程涉及更多的工作量和精度,但这能保证伞的翼形更干净整洁,也意味着更好的性能。
用更少量的伞绳长度来铸就“三组绳”的伞,这个理念让我们构造出同时具有极佳飞行性能和高度被动安全的伞翼。把伞绳概念化的方法,让生产更抗塌陷的伞翼成为可能。即便发生塌陷,也通常是小面积范围。这一点极大提升了伞翼在极端飞行状态下的表现。
与常规伞翼相比,重量更优的这一类伞翼更轻质——但却拥有通用的机械稳定性和耐用性。轻质的伞携带更轻松,起伞更轻盈,因此非常适合登山飞行。我们做的重量优化,是针对既想要轻质又不想在耐用性上妥协的飞行员们。
就像用一张纸去包裹一个球形,纸面总会有褶皱一样,滑翔伞的伞鼻也面临同样的情况——伞衣要满足剖面翼形和球面效应(气室是弧形而非直线型的)的双重需要。双层3D塑形技术采用额外的一层缝线来减少折痕,以此提升伞翼性能。
On a paraglider, pilots are accustomed to seeing a trailing edge that is as straight as possible. However, during our glider tests we discovered that on some models
- more brake pressure is required;
- the handling is worse;
- the aerodynamics and thus the performance are negatively influenced, because more line meters means more drag.
The Low Drag Brake foregoes the perfect look in favour of better handling and performance.
