  • R&D team comments

    APOLLO BI's designer Alexandre Paux explains how and why APOLLO BI is different from Metis 3.

    “Traditionally, when I create a tandem glider, I pay a lot of attention to making it very suitable for the commercial pilots. That is to say I design in specific characteristics such as super easy take-off and landing and a roll rate which must be easy on the passengers stomach.

    “The priorities when designing a performance tandem such as APOLLO BI, are quite different.

    APOLLO BI is built with the ability to be flown far and comfortably for many hours at a time. That means lighter handling, larger speed range, better glide & more feedback from the air.

    Sure, handling is sharper and a little less forgiving than our METIS 3, and launching is more demanding because of the shark nose and thinner lines, but this compromise is giving the performance increase and sublime feel in the air to a very special and specific glider for the skilled tandem pilot to really enjoy and excel with.”

  • Story behind the new design

    Our Sport-line Series is all about beautifully crafted performance enhanced products.

    We meticulously produce these products to include all our very latest innovative details and features that combine and add up to make class leading and cutting edge differences, without compromise, that our performance minded customer’s desire.

    We seriously believe that true performance comes from the right match of pilot and wing. The same statement equally and firmly, applies also to safety.

    And so, the Sport, Comfort & Light lines were born to perfectly address these statements and allow our design team to fulfill many different pilots’ needs, whilst offering the most suitable product for the individual pilot. Choosing the most suitable product becomes an easy, pleasurable and logical experience for any level of pilot.

    You will find the same philosophy flowing throughout all our products, whether it be a glider, reserve, harness or the smallest of items such as a speed bar or brake handle.

    Our young and dynamic additions to our traditional design team have injected the Sport-line with passion and performance, based upon a solid design platform which has evolved for over 25 years at Sky.

    The APOLLO BI was born from these philosophies and strong beliefs, a true Sky thoroughbred which honestly defines our Sport line glider series.

    Whilst this glider is cutting edge and certainly not for inexperienced pilots, it offers the skillful pilot the ultimate performance and in-flight experience within its class whilst retaining the slick handling that Sky pilots around the world adore.

    Design Features

    New nose, new foil, new line distribution, higher aspect ratio. Welcome to the world of Sport-line. We wanted to produce a wing that was truly technologically enhanced, stylish and class leading. It comes in the form of APOLLO BI.

    Creating APOLLO BI with a drag reducing 3 line concept and at the same time creating a stable nose section at higher speeds meant that our story was just beginning.Load distribution dictated that a slightly thicker profile was required compared to our previous models. We kept this foil clean with our Triple 3D cut, a double 3 D cut on the top surface and single on the lower.

    The new V Bridge internal structure is required to deal with load distribution whilst reducing ballooning and flattening of the cells.

    Our LEO (Leading Edge Optimisation) was derived at after extensive testing.

    A closer look reveals its unique structure and blend of materials which offer both aerodynamic and practical advantages.The shape of the nose and the air intake position is optimized for excellent pressure values throughout the speed range whilst the nylon rods, Hypalon and Mylar help to maintain nose stability due to its extended distance beyond the A line attachments. Traditionally, leading edge nylon rods are a point for abrasion so we moved the rods slightly inboard from the top surface to fix this and kept the rigidity by using the composite structure.

    Finally, cell supporting mini ribs in the trailing edge are the finishing touches to complete a very clean and thus efficient foil.The blend of all these innovations work together in harmony to produce APOLLO BI's stunning handling and performance.
