A. About the Z-ONE
Materials
The use of high-tech materials guarantees a long life and a damage-resistant,
reliable glider. These are our pre-requisites for quality manufacturing of
Firebird gliders. Appropriate care and maintenance of your equipment will
guarantee its longevity and years of flying pleasure.
Firebird's canopys use 40 g/m2 Porcher Marine Ripstop Nylon with Softfinish
for the top and under sail, Hardfinish for the ribs, and an especially water
resistant coated top sail. The cloth has been chosen for its excellent UV
resistance and tear strength.
Our DHV approved lines are made of ARAMID-Centers with a polyester
sheaths. These materials have been tested rigorously in order to pass DHV
certification.
Canopy Construction
The canopy of the Z-ONE has 40 cells. The specially-cut cell entries on the
leading edge guide the Rammed air created through the air flow into the
canopy.
The profile of the Z-ONE is due to the profile and diagonal lines which connect
the top ands under sail and thus equalize and distribute the pressure on the
sail evenly. Pressure equalizing openings in the cell walls permit a
homogenous distribution of pressure throughout the canopy. The basic
construction and design of the Z-ONE give it its notable stability even in
extreme situations.
