2. ABOUT THE WING
Who should fly the Freeway?
Freeway is a small universal canopy designed for those who like to have good fun
in the air, including some aerobatics. It is versatile enough to use a few thermals
for a small xc, try some acro, have some fun on the dunes, make a couple of
hops from small hill or simply... indulge in groundhandling for a while.
THE PROJECT
The goal of the Freeway was to focus on its manoeuvrability, thus presenting
pilot with perfect feeling and fun, while keeping good performance so that
staying in the air will be easy when thermalling or soaring. In order to achieve
all that we had to meet several points:
+
easy and playful character in ground training,
+
good pitch stability accompanied with dynamic roll behaviour,
+
120% of usable steering range (brakes operational below stall point),
+
good behaviour in basic acro manoeuvres (SAT, helicopter etc).
+
clean design resulting in good performance data.
The Freeway was to be simultaneously fun and safe – that’s why we
preferred small size for dynamic behaviour and kept modest aspect ratio, so
that it could be certified with really wide weight range (55-100 kg ).
DESIGN
Entire body of the FREEWAY was designed under our
Canopy Shape Guard scheme, combining multiple
subsystems and resulting in exceptionally coherent
and durable body. For more details on individual
subsystems, read on.
Every second chamber is divided in two cells, and the ribs are additionally
supported by VSS (V-shaped supports). Such design practically guarantees
smooth top surface, exact aerofoil reproduction across the entire wingspan,
better load distribution and yet more importantly, as few suspension points as
possible.
All along lower surface there is RSS (Reinforcing Strap System) employed -
a different (than usual ballooning scheme) way of
making the wing more rigid and stable.
On the leading edge we applied the FET (FlexiEdge
Technology). Elastic rods make the leading edge
