there are large dotmatrix printers that can print onto fabric. we have tested the process on ripstops and you can not print onto zp you can however print onto f111. we manufacture large banners for towing behind helicopters and the company we work for sometimes has digital prints onto 1.8 oz ripstop. You could have this done and then use the printed material for the bottom skin of the canopy, with zp for the top skin. The manufacturer would need to provide patterns for the bottom skin panels to account for seam overlaps. Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

we recommend 24" pilots because they are safer in the event of a premature deployment at freefly speeds. for normal deployments you will not notice a difference between a 28 or 24" pilot. as to the openings being faster, they probably are slightly: canopies will always feel a bit different after jumping a ragged line set to a new one. give it a bunch of jumps, settle in puting some time on the canopy, any issues give us a call. -d Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

the diamonds are not appliqué they are structural. as such the diagonal seams extent from nose to tail. the x-1 has the both top and bottom skin. -d Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

I think what you are referring to is the slight flattening of a canopy's arc when loosening the chest strap and spreading risers. a high res image of the X-1 wing is attached. Its gorgeous. Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

will, do. as to the posted pic. im not seeing what you are referring to. i can tell you from all the high res pics and data we have the X-1 canopy shape is super clean, wrinkle and distortion free. Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

Thanks Chuck.... Some general specs: The X-1 is a 7 cell (21 chamber tri-cell) X-brace wing. In fact the first tri-cell I have designed. We have always produced canopies with slower high lift airfoils and short line sets, but the X-1 is a very different animal. It uses a new high speed airfoil and a longer line set. The X-1 was designed strictly for pro-level swoop competitors ! Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

you can count on me bringing a 95 X-1 with me to the ranch as soon as the snow melts. Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

hey chuck, it wasnt an onyx replacement, but rather a new canopy designed specifically for our competing swoopers. the onyx is a brilliant canopy but perhaps misdirected in initial marketing. the onyx is hands down my favorite canopy i have ever jumped or made. it is ideally suited for intermediate to high experience jumpers wanting a high performance but everyday canopy. it is an extremely low distortion, high efficiency wing, which means you can jump a size smaller than you would with other designs. openings are super soft, consistent and ordered. the canopy is fun to fly, has a neutral recovery arc and has tons, and i mean tons of lift/flare. it is a very forgiving high performance swoop canopy, at light loadings it is a great first x-brace and at higher loadings it will thrill all but the most hardened swoop competitior. the only negative feedback we have ever received is that it can not out swoop a velocity....but it wasnt designed to....after having bryan bug me for two years i finally made him a canopy that was....it was unofficially dubbed the VK at pia... ask bryan what he thinks of it.. -d Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

"but Cobalt has 4 tapered cells, " please note this is not correct: the cobalt is a 9 cell canopy with 5 square center cells and 2 linear taper cells (cut straight, not curved) on each side. Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

In order to receive a patent one must "reduce to practice". Atair fully reduced the invention to practice, performing the r&d and even fielding several military products. This was long before the RWS development effort (now UPT). Bill Booth apparently did some development work without first checking for prior art. When he did, he became aware of our prior work. We were then contacted by Bill Booth to license our technology. Bill even though apparently having hit on the idea independently but after us, had not fully reduced it to practice. We gave him the technique for installing the magnets which prevents negative effects from cracking, among other small details. Many people do not realize that the language used in patents represents a specific legal format and legal requirements. for example: proper claims are to be written much akin to a Venn diagram: starting all encompassing and then getting narrower. Because a patent uses broad language, does not in any way mean that detailled designs and development were not done. we were in no way required to licensed the technology to Bill, but decided to because we felt he would do it justice and UPT assured us they would widely implement it into the industry, creating a new standard. As we are primarialy focused on military work UPT's reach in the sport industry interested us, as did the good will and recognition they promised to create for Atair. I hope everyone will enjoy the feature on UPT's new rigs. Sincerely, Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

just got back to ny from the pia. actually the fabric is not sail material, although it was inspired by. we have developed a continuous web process for producing non-woven parachute and also ballistic protection fabric. the fabric is produced in house by atair on specialy built machinery. - Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

The space canopy was identical to the alpha (also called the impulse). This canopy was the predecessor to the cobalt. The difference in the cobalt was basically in construction: 18 panels were used on the top skin instead of 9. every seam was frenched and no i-beam seams were used in the cobalt. the space canopy was privately labeled for skydepot. as to sizes we do manufacture a 170 size of our cobalt and comp cobalt, and for this season we will soon be offering sizes up to 210. we are extremely busy with military work and the upcoming pia, but look soon for our new website. it will be updated with the latest models, &sizes. sneak peak: we now offer a complete line, having added new canopies, reserves & rigs too! sincerely, Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

brian, the canopy in your pictures are of a new demon proto we made. it was un-named at the time we sent it to you. it is slightly higher aspect ratio than the radical at just over 3:1 different feel. both canopies are a blast to fly. .

btw: the patent holder of ultrahigh molecular weight polyethylene is DSM in the netherlands where the fiber is produced under the trade name dyneema. honeywell (allied signal) licensed the technology from dsm for production in the u.s. and produces fiber under the name spectra. and whereas spectra can shrink and go out of trim after as little as 300 jumps, this really only happens on canopies that open very quickly. most modern canopies with soft openings using spectra will remain in usable trim for 600-1000 jumps. - Daniel Preston atairaerodynamics.com (sport) atairaerospace.com (military)

once in flight, stabilizers serve no purpose and are definitively only drag. btw the aerodynamics of winglet design is not a trivial task. there have been many attempts at adding winglets to parafoils, some even commercialized. however none work and ALL are drag. the simple proof is to fly the wing with only one winglet and view the direction of the induced turn. .

we datalogged a max speed of 121mph comp cobalt 120 535 pounds exit weight flown by john heady. (think a good portion of the weight was his balls) we also routinely drop our autonomous guided systems with 2400 pounds under a cobalt 350. they fly at 85mph level and can accelerate to over 120 in a spiral. .

>> Dacron lines do absorb some shock from opening, which has proved effective on canopies which open quickly e.g. early parafoil canopy designs, or modern canopies which must open quickly such as base parafoils. where dacron falls short is its application to a modern skydiving parafoil. modern skydiving parafoils limit opening shock instead of generating it and trying to attenuate it with stretchy lines. modern canopies limit max g force by controlling the rate at which they can inflate and hence the drag, generating a force vs time profile that is stretched out compared to canopies of old. the longer you spread out the opening the lower the g force. much more sophisticated designs exist now than 10 years ago. designs which limit the conductance of air inflating the canopy via specific designed geometry in the nose inlets, crossports, planform, line set and slider. again it is all about not generating high forces at all, instead of generating a high g shock and then trying to attenuate it at the lines before transfering to the jumper. you might ask, well then why not add dacron lines as a back up, to protect against a fluke opening or improper packjob? dacron is a low strength fiber by todays standards. the specific tenacity is about 1/5 that of spectra. dacron lines must be far bulkier and much higher drag, additionally due to their high stretch it is not possible to use on many modern parafoils, e.g. modern parafoils are higher performance and designed to keep a specific shape to higher tolerances that older canopies. lines that can stretch beyond a certain limit will allow the airfoil to mis-shape beyond its design parameters causing instability.
