4. Technical Description:
Construction of the canopy:
The canopy of the Voyager Biplace is made of Porcher Marine Skytex Ripstop Nylon-fabric Art. 9017 E77a and
Skysport D70. In this synthetic fabric a reinforced thread-net is woven in, which stops the fabric from further
tearing and is increasing the firmness at the seams. The coating makes the fabric water-repellent, UV-stabile
and air-impermeable.
The Voyager Biplace consists of 46 cells. The wingtip (stabilisator) is pulled downwards and is intergrated in
the canopy.
The aeration of the canopy is done through the openings on the bottom side of the profile-nose. The lateral
aeration is done through exactly dimensioned openings (cross ports) in the profile-gill.
Every carrying profile-gill is suspended from 4 Line-attachement-points, which are reinforced in the profile
itself.
Between the single groups of main lines are taut ribbons sewn in, which are regulating the tension of the sail.
At the profile´s nose reinforcements are sewn in, which gives the canopy more stability.
On the entry- and trailing-edge of the canopy a special ribon with low elongation is sewn in, which offers a
cunning, by our design-software calculated, tension-distribution along the canopy.
Suspension-system/Line-system:
The lines of the Voyager Biplace consist of polyester-covered HMA Aramid and polyester-covered and
uncovered PES / Dyneema, depending on where the line is placed. The strengths of each line depend also on the
place where the line is built-in, and are varying between 100
The lines are differing depending where they are built-in like follows: Top-lines (up at the canopy), middle-
section-lines (between main- and top-lines), main-lines (down at the riser), stabilisator-lines (at the wingtip)
and brake-lines (up at the trailing-edge) and main-brake-lines (at the brake-handle).
The lines are differentiated in A / B / C / D level and the brake.
Within the levels always 2 top-lines are combined to one middle-section-line. On the main-line level always 2
middle-section-lines are combined to overall 6 main-lines per level, which are mounted to the maillon rapides
shackles at the corresponding riser.
The stabilisator-lines are mounted to the B-riser together with the B-level.
The brake- or steering-lines are combined to the main-brake-line in the same way.
The lines of each level are coloured differently to make it easier to differentiate and check it.
The complete riser of the Voyager Biplace consists of 5 risers on each side.
The A-riser is splitted in a main(A)-riser and a sub(A´)-riser (also called outer- or baby A´riser). On the A-riser
2 main-lines are attached, on the A´one main-line is attached.
On the B-riser per side 3 B-main-lines plus one stabilisator-line are attached.
The C-riser takes in always 3 C-main-lines, the D-riser takes in 2 D-main-lines.
The main-brake-line is running through a pulley at the D-riser to the brake-handle.
The maillon rapide shackles at the risers are made of stainless steel and are secured with an plastic-inlay
against unintentional opening and against a slipping of the lines.
The complete geometry of the lines is shown on the single line plan, which you find a few pages behind.
Speed-system:
The Voyager Biplace M and the Voyager Biplace S (for tandem-flights) have got a Trimmersystem at the D-
Riser.
The trimmer elongates the C and D-Riser and reduces thereby the angle of attack of the canopy, what increases
the trim-speed.
In normal flight all risers have the same length (37cm with the shackles). If the Trimmer-system is activated the
C-risers gets up to 2,5cm, the D-risers up to 5cm longer. The length of the A- and B-riser does not change
and 340 daN.
.
Functionality and handling:
The trimmers influence the take-off and flight-behaviour! In normal-flight-position all risers have the same
length, that means the trimmers are pulled down. To accelerate the glider the adjustment-buckles of the trimmer
have to be pushed. Thereby the C/D-risers are getting longer, the angle of attack of the paraglider decreases, and
the trimm-speed gets higher. The adjustment-buckles can be adjusted steplessly from “completely closed” up to
“completely opened”. Both trimmers always have to be adjusted symmetrically to the same position at both
risers. The adjustment of the trimmer-position also offers the possibility to optimize the takeoff-characteristics,
depending on the take-off-weight and wind-situation.
For single-seated flights the Voyager S can be equipped with longer risers with a speed-system which can be
activated by the legs of the pilot. As soon as this speed-system is released it automatically returns in normal
position. This riser-version does not have trimmers.
This speed-system for single-seated flights of the Voyager S shortens the A/B/C risers and reduces the angle of
attack of the canopy. In normal flight all risers have the same length.
Before take-off the Brummel-hooks of the harness´speed-bar are connected to the Brummel-hooks of the
speed-system at the risers. You have to take care that the line of the speed-bar is running free.
Before the first use of the speed-system you have to adjust the length of the speed-bar´s line correctly.
