Orca XX
Orca XX
Orca XX is a universal tandem wing of EN B class and 5,3 aspect ratio (53 cells). It offers exceptionally easy launch, perfect handling and highest passive safety accompanied by performance of a single-seater.
Design and purpose
The paraglider is dedicated both for free-flying with passenger and for light paramotor trikes.
Four-row canopy with rigid cores (Dudek FlexiEdge technology) blends recent experiences of testing other prototypes featuring this technology with long-standing info received over years from happy users of the original Orca.
The aspect ratio and other factors were carefully calculated in order to make full advantage of new technologies, while retaining optimal mix of passive safety, performance and steering for this class.
The aerofoil used in Orca XX has Shark-nose intakes – they help to internal pressure of the canopy stays stable within wide speed range.
Inner reinforcements, structural cores and mini-ribs perfectly shape and stabilize the aerofoil. Mini-ribs on the trailing edge keep it slim and decrease ballooning, radically improving the airflow. Rigging has been redesigned too – total lines length decreased by 15% as compared to Orca, bringing further improvements. All in all, we succeeded in creating a perfectly balanced design, mixing great performance with safety and stability. In turbulence the paraglider behaves very reassuring and predictable, with efficient damping of both longitudinal and lateral oscillations.
OrcaXX easily inflates and rises, without lagging behind. Then it stabilizes and with slight brake action simply flies away. On the landing approach it is enough to brake down a little in order to markedly decrease speed with ensuing soft touchdown. All tandem pilots appreciate those features, so we’ve put quite an effort into polishing them to perfection.
DESIGN
Canopy of the Orca XX body was designed in our CSG (Canopy Shape Guard) system, comprising a number of elements resulting in exceptional coherence and stability of the shape.
Another feature of the Orca XX is the Flexi-Egde technology. The leading edge is closed to the airflow, and its precise shape is kept with laminated cloth reinforcements, incorporating synthetic rods. The rods make the leading edge stiffer and smoother, bringing improvements in many areas – from easier inflation, through stiffening the canopy in flight to improved general airflow.
The intakes are located on the undersurface in the vicinity of leading edge. Their position was chosen very carefully, so that they got maximum ram effect in possibly many flight situations.
The wing tips additionally feature ACS (Auto Cleaning Slots) – as the name suggests, these are dedicated openings automatically removing dirt from inside the canopy.
Careful selection of modern fabrics and design solutions brings about great strength and durability of the Orca XX. All materials used come from marked production batches, and each production step can be verified down to identification of specific worker and controller.
