Litespeed S


The king posted Litesport hang glider performs similarly to a non-kingposted glider, but handles like an intermediate glider, making it suitable for many pilots whether competitive or recreational. Gerolf Heinrichs, the design engineer, has utilised many of the technical advantages of the Litespeed to design the thick leading edge tube, fipeglass wing tips, and the CAD/CAM design and manufactured sail, providing a clean and tight leading edge surface for high speed glides. The Litesport uses a 7075 alloy frame with the 62mm (2 7/16in) leading edge with curved glass tips from the Litespeed. The thicker and stiffer tubing assists with leading edge wind deflection experienced at high speed as well as providing a sturdy mounting point for the dive strut.

The cross bars are manufactured from a high-grade carbon fibre, which have been further enhanced for the new Litespeed. The carbon fibre spars are manufactured utilising yachting American Cup technology. Each carbon fibre spar is constructed of pre-impregnated fibre cloth and cured in a pre-heated oven at 120 degrees Celsius for 1.5 hours. The lay-up schedule incorporates unidirectional fibre, biaxial fibre, and woven cloth, which are laid in a sequence that optimises strength, flexibility and weight.

Bridging the gap between flex wings and rigid wings in terms of performance, the Moyes Litespeed provides high speed capabilities, sink rate and climb rate by being lighter than earlier models. The Moyes Litespeed still provides strength, durability and structural integrity, designed by Gerolf Heinrich, an Austrian team pilot and a certified aerodynamicist.

The sail is designed and manufactured with the same CAD/CAM system used for the Litespeed. The sail is precision cut and assembled, providing an extremely smooth and clean wing surface. The Litesport's standard sail is constructed from Powerib (Dacron). Alternatively, a high performance PX10 Mylar sail is available.
The Powerrib (Dacron) material provides a slightly more forgiving flight, whereas the Mylar sail, which is considerably stiffer and therefore provides higher performance. The Mylar sail is constructed with a PX20 leading edge and PX10 used on the remaining top surface. PX20 is a thicker Mylar material to the lighter PX10. While the Powerrib has traditionally been considered more durable, the new PX Mylar materials have advanced considerably and would now match the Powerrib in this area.

The battens of the Litespeed are also constructed from the 7075 alloy. The upper surface battens are contained within the sail using a spring-loaded retention device. This method provides easy installation of the battens while ensuring a clean trailing edge, further minimising drag. The under surface battens are installed through a small hole in the sail and are held in place by a recess in the batten sleeve.

The Litesport's kingpost adopts a G-String compensation system, which requires only one luff line and a single dive stick to minimise drag and weight. As the VG is pulled on, the kingpost mounting point for the top side wires is lowered. The single luff line is secured to the top side wire instead of the kingpost as with conventional gliders.

Another significant contributor to the diverse useable speed range on the Moyes Litespeed is the dive stick design. The dive sticks are attached and pivot from the leading edge, however the cable support for the dive stick is attached to the carbon fibre spar. With this design, when VG is off, the dive sticks are optimally positioned to provide low speed stability and handling. However, as VG is applied, the dive sticks will lower, flattening the trailing edge and providing a more aerodynamic profile to improve the gliders high speed capabilities. Despite the extra functionality, the VG system is extremely easy to operate.

The mounting point of the luff line is set 250mm forward of the trailing edge, providing a more reliable reflex action from the luff line. On most kingpost gliders when the luff lines apply pressure, the trailing edge curls up. With the Litesport's system, the trailing edge is raised evenly, which has proved favourable during certification testing.

The diverse range provided by the VG and G-string systems are a key feature of the Moyes Litesport. When the VG is off, they provide a loose, flexible wing with a raised trailing edge for launches, landings and thermalling. When the VG is applied, they provide a tight, flat sail for high speed glides. The superior handling of the Litesport is also complemented by the low wing tip inertia due to the gliders low weight design. As less hardware is used in the wings (ie. One dive strut and one luff line only) the glider feels more responsive, easier to turn and even easier to straighten.

Glider stability is enhanced with a slightly increased sweep angle, inbuilt sail twist and advanced dive strut design. The positioning of the luff line in from the trailing edge also offers more reliable reflex when required.

The glider comes standard with aerodynamic uprights and a standard speed bar with rubber grips. The A-frame is made of an aerodynamic 7075 alloy tubing. The Litesport can be optionally fitted with a Fast base bar made of aerodynamic alloy tubing or the Zoom A-frame.

Gerolf Heinrichs won the last day at the Australian Open 2002 and Jon Durand Jnr won the entire Australian NSW State Championships 2002 flying the Litesport.

The third generation of the innovative Moyes Litespeed range is the Moyes Litespeed RS. This glider has been specifically designed for racing and offers a larger wing span and higher aspect ratio providing enhanced glide and climb characteristics. The Litespeed RS top sail surface is fully constructed from PX Mylar cloth and is standard as a full white surface with Titanium Oxide finish to reduce UV effects on the sail. An optional smoke inlaid sail is also available. The smoke inlaid sail uses a lighter semi-transparent dark Mylar cloth in the centre of the wing surrounded by white PX Mylar. In addition to being aesthetically pleasing, the smoke inlaid sail reduces the weight of the sail by approximately 1.5kgs. The under surface is made from Dacron, and is divided into three areas which can be customised to suit the colour requirements of the pilot.

The Moyes Litespeed RS is supplied standard with full aluminium leading edges, carbon fibre cross bars, standard aerofoil uprights and a round base bar. The glider flies extremely well in this configuration, however glider weight can be reduced and handling improved through the inclusion of an extensive range of performance options.

If using the standard uprights, an aluminium aerodynamic FAST base bar can be added. The preferred option is to upgrade the A-frame to the Moyes Zoom uprights and carbon fibre speed bar. The Moyes Zoom uprights feature an extremely aerodynamic profile constructed from extruded aluminium and presented with an electrically etched black finish. The Moyes Zoom carbon fibre speed bar uses the same aerodynamic profile as the Zoom uprights. The base bar is hand laid using pre-impregnated carbon fibre cloth and is pressure cured at a high temperature to ensure an attractive and durable finish.

A range of carbon fibre performance options are available when ordering the Moyes Litespeed RS. These include carbon fibre outer leading edges, carbon fibre inner leading edges, carbon fibre dive sticks, carbon batten set and carbon fibre leading edge inserts. Except for the carbon batten set, all these options are hand laid using pre-impregnated carbon fibre and pressure temperature cured to provide light yet strong components. The carbon fibre options provide a stiffer and lighter alternative to the standard aluminium components, contributing to the handling and performance of the glider.

Moyes Litespeed 4S

 

Moyes Litespeed "S".
The "S" refers to the sail cut design being applied to the Litespeed. Sail area has been removed from the chord or root of the sail and redistributed to the mid and outer wing. This results in an "S" shape along the trailing edge - or in more technical terms - a "super-elliptic" wing planform.

The sail cut is intended to counteract the typical mid-wing lift deficit of flexible hang gliders. The creation of a super elliptic wing planform in other words just compensates chord wise for the inevitable washout of flex wings - resulting in a better, more elliptic lift distribution.  A wider mid wing and tip cord allows more of the outer wing to create lift along the wing span - the glider's effective aspect ratio thus increases without additional span. The nominal gain in glide and climb is expected to be only about 1.5%, however a major improvement of the new Litespeed S comes much more from a significant improvement in slow speed manoeuvrability.

The Litespeed S can be flown 2-3km/h slower with this enhanced manoeuvrability becoming more apparent as more VG is engaged. Thermalling in light lift with up to 50-70% of VG, and very efficient dolphin style flying are the key advantages that top pilots will achieve with this new model.

In addition to the new cut sail, Moyes have also introduced a range of new high performance options including a carbon fibre outer leading edge, carbon fibre dive struts and a lighter redesigned carbon cross bar. All these options reduce the overall weight of the glider by about 2kg. With the weight reductions mostly towards the mid wing and tip, the wing's roll inertia is reduced significantly. This leads to an amazing gain in handling, especially at slower glide and thermalling speeds, especially at tighter VG settings. Since overall measures of the wing frame have been kept unchanged, all these performance options are fully modular and interchangeable with the standard aluminium components so pilots can select the options that best suit their individual needs.
A new size was also added to the Litespeed range. The new Moyes Litespeed 3.5 offers a smaller sail on a Litespeed 4 frame, offering the perfect glider to pilots in the 70kg weight range.
