“She’s a wing of legends. The Kraken is the ultimate 'party in the front and business at the back', she's super responsive and holds tight when pushed hard. She is the canopy equivalent of Che Guevara, Marilyn Monroe and Brian Jones all in one. The Kraken is a must have for any wingsuiter and will have the pilot grinning ear to ear as they fly back to whatever landing area they can make it to. Kidding. Kinda.”
We have released the Kraken, finally! Designing the Kraken was a long process because it was new to us: the Kraken is our very first wingsuit specific parachute. Traditionally NZ Aerosports has focused more on flight performance than on opening a canopy in a wingsuit wake. So it took us a few years, but ended up with a very technical end result: a canopy full of cool features and ideas that makes it very different from any existing wingsuit canopy. The result is a low bulk, long lasting canopy with very reliable and stable openings that lands like a dream.
Typically, canopies low(er) in aspect ratio and ellipticity (fat 7-cell canopies) have better heading performance, and stability in flight. The problem with this is that wings shaped like this are not exactly renowned for their glide performance and sharp handling. The solution to this problem was a combination of ideas floating around the head of NZ Aerosports’ aeronautical engineer Julien Peelman, and the production and test jump team. We looked to our deep understanding of modern day wings, aerodynamics, and type of ingenuity that produces world class skydiving parachutes – our trademark.
Key features of the Kraken
3D Designed: We are now using Catia V5 to design canopies. This is one of the most advanced 3D CAD softwares available. It gives us more freedom to design the canopy down to the finest details and helps generate the most accurate panels possible. The result is a more accurate shaping, a smoother surface, and better aerodynamic efficiency.
CFD Tested: The Kraken shape has been tested using CFD (Computational Fluid Dynamics), which gives us, among other things, a better understanding of her behavior in turbulence and during recovery.

Anticipating the zag: First debuted in our Crossfire 3, The Kraken is designed so its panels are designed directly in the shape they will have during flight by taking into account the Zig-Zag distortion. This spreads the load evenly through the fabric and makes the wing more structurally efficient.
New Rib Shape: The Kraken has benefited from research on rib shaping that was originally used to design our new range of hyper-performance wings, Petra and Leia.
New Crossport Design: Crossports have been strategically placed in the Kraken to have the least influence on the upper surface shape while allowing a good air circulation between the chambers. They are bigger toward the center of the canopy to help with symmetrical openings. They have also been designed with an elliptical shape that optimizes their area while reducing the upper surface distortion.
Powerband: We've added the split leading edge Powerband to all our new canopies since we pioneered it with Petra. It allows us to better control the aerodynamic shape in the nose area, which prevents parasitic drag.
Curves in the right places:
We’ve realised that by sewing our reinforcing tape in parabolas (arcs) on the ribs, we spread the load applied to the top surface more efficiently, meaning less distortion and a more efficient top surface.
Don’t say slit:
We’ve put a vent on the lower surface to help promote fast center cell inflation. This means better, more on heading openings in the messy wake of a wingsuit. It’s not a gaping hole like a BASE vent, it’s a… horizontal opening... that seals after full inflation.
There’s a hole in my slider?!:
We became so fond of vents that we put one in the slider! We found that by creating a channel for the air to go straight through, we reduced the crazy oscillation often seen during parachute openings. Those oscillations can contribute to off headings etc, so that’s nice!
To help out its closest neighbors, the crossports leading from the center cell to the closest outboard cells are enlarged. Promoting symmetrical central inflation means promoting on heading openings!
Keeping it short:
Shorter lines mean more flight stability, and easier rectification of any pesky line twists – both good things for the whole wingsuit deal!
High-tech, low bulk:
Because it’s 2019, we haven’t used untreated cloth (F-111) for our wingsuit canopy. Instead, we’ve tracked down a low bulk ZP (treated with silicone) fabric, and used that for the majority of the wing, with the Powerband and top center panel made out of standard ZP for extra longevity.
We’ve included a bit of internal structure that means your bridle will load both your risers more evenly during the early stages of deployment. Because of how it looks, we’ve called it the ‘Bow-tie’ – and as we all know, equality is classy!

Little tail thingys:
Mini-ribs in the tail of a canopy sharpens its profile, which reduces drag and increases glide performance by “a lot more than we thought”. This translates to more fun in the sky, and a better flare on the ground. 7 cells are not usually known for their amazing flare power, so it all helps!
Improve your pull-out game with a snatch:
Symmetry is good, and so it is with your pilot chute. We’ve discovered that using snatches help with our wingsuit openings, so we have stocked up on them and highly recommend to purchase one with all Kraken purchases!
Inward Rotated end cell:
While most ribs are perpendicular to the lower surface, the end rib is rotated inward to reduce the size of the end cell and prevent it from losing its shape. This reduces tip vortices and induced drag.

New line trim:
Despite being a relatively docile canopy, the rectangular planform has been compensated with a trim just a notch steeper than you would think. This helps with up wind penetration, fun and is one of the reason for the great flare.
New Stabilizer shape:
The shape of the stabilizer has been modernized to prevent it from flapping too much in flight. It also helps the slider to sit in the right position. Custom Sizing The Kraken is available in any size between 119 and 189 so that you can get the perfect wing loading for you at this stage in your canopy progression.

Key flight characteristics of the Kraken
Openings The modern day wingsuit is capable of incredible glide, but this efficiency brings its own set of complications when designing a parachute to match. The biggest factor is the turbulent wake formed behind the wingsuit – right where the parachute is deployed. Kraken openings are quick but not hard – you’ll feel inflation immediately. The vent helps control the heading. Once the center cell and adjacent cells inflate, the canopy slowly pressurises with a predictable reliability. The Kraken will sail on level seas even with linetwists! Inputs Intuitive and precise, each input delivers a predictable response. From opening to landing the Kraken is a confidence builder. Toggles Big inputs will produce an immediate response - the pilot will feel in control from first point of contact.
The slow flight characteristics were a very important design factor for the Kraken, so there is plenty of warning before she stalls, and will recover to normal flight in an easy and stress free transition when slowly letting the toggles back up.
There’s lots of feel and response – the Kraken has fantastic glide! Milk those rears and disprove the myth that all wingsuiters land off! Front Risers F is for fun! Yep, the Kraken can dive!
The Kraken has loads of zip! Fly her nice and slow for those busy landing patterns when you want lots of vertical separation. Or dive her at the ground and drag some turf. There’s plenty of fun to be had!
The recovery arc is longer than typically experienced with similar 7 cell designs. For someone who wants to have their cake ( a nice sensible wingsuit canopy) and eat it too (swoop the shit out of it), then go go go! Flare The Kraken has a wide range of performance, the flare is one of the most important aspects - she wont disappoint. Those nil wind tiptoe landings will feel very natural.
