Synergy
The
Details
The Synergy 
The Synergy is a 7-cell lightly
elliptical zero porosity canopy that has been described as "possibly
the best all-around parachute that Precision has ever produced."
From pitching the pilot chute opening the canopy to pulling the
toggles landing the canopy, we have developed a parachute that
delivers predictably consistent performance tuned to the styles of
both newcomers and old-timers alike.
Precision Aerodynamics
president George Galloway has been jumping out of airplanes since
1972, enjoying an interesting career as a pilot, parachute designer
and test jumper. He is "A-License qualified" on reserve rides alone,
and certainly has his choice of any canopy out there. He chooses to
jump the Synergy. "During my career of skydiving, I have seen 'em
all and made most of them", referring to the fact that he has seen
and manufactured everything from military rounds to cross-braced
pocket rockets. "At the bottom end of a skydive, the Synergy gives
me the kind of solid performance I like without having the worries
associated with little zip wings. If I have to, I can settle the
Synergy into a back yard or some other off-dz area without much
concern."
The Synergy was designed
specifically to be performance-sensitive depending on its wing
loading. If you load the Synergy in the range of 0.8 to 1.0 lbs/sqft,
the gentle and docile ride is appropriate even for novice
parachutists. As you increase the wing loading toward the maximum of
1.5 lbs/sqft, the Synergy transforms into a quickly responsive and
speedy ride that will prepare you for moving up to higher
performance 9 cell ellipticals.
Easy Openings and Flight
Stability 
Most all 7-cell non-rectangular mains on the market today are made
out of zero-porosity fabric and exhibit a couple of very attractive
characteristics, namely easy openings and rock solid flight
stability. The Synergy has been aerodynamically tuned to maximize
these traits, and at the end of the ride there is still plenty of
energy left to produce a powerful landing flare with a relatively
short toggle stroke.
The Stabilribs
Like all other
canopies in the Ground Zero project, the Synergy is designed and
manufactured with our exclusive Stabilrib technology, wherein the
outboard suspension lines are attached directly to the bottom of the
stabilizer panels, eliminating flight flutter and contributing to
the solid flight control and landing flare. Take a look at the
stabilizers during flight on the canopy you are jumping now, and
then compare that with your experience under the Synergy. The
difference is remarkable, and when combined with the HMA lines, the
result is increased flight efficiency that translates into returning
you to the airport when others just can't make it back.
The Lines The Synergy is lined with
a High Modulus Aramid fiber specially constructed for us to use in
the Synergy and other Ground Zero canopies. The rigging is
continuous, meaning that there are no cascades in the lines between
the links and the canopy. The HMA line is very thin, and the
reduction in parasite
drag is clearly evident to anybody who jumps the canopy. Line drag
is a significant factor in several elements of flight, and any
reduction to drag in any wing is beneficial to higher efficiency
flight. The HMA line wears better than Vectran, has the strength of
Spectra, retains its original trim like Kevlar, and has all of the
good qualities of Dacron without the bulk. HMA line is available in
352, 440, and 946-pound tensile strengths, and the braided diameter
is smaller than either Spectra or Vectran. Our experience during the
past two years indicates that HMA line not only packs smaller, it
also tolerates the slider's friction quite remarkably, while at the
same time retains its linear stability as well as Vectran.
