Astral 4


The team of Günther Worl and Manfred Kistler introduced the Astral for 1998.

Dedicated work on proven profiles (Astral and Arcus) as well as unconventional methods with Research and Development (Inboard Camera) have resulted in the Astral 2.

The goal was for improvement in climb and glide ratio, as well as improved stability, for ambitious recreational pilots. A result is dampened reaction from the glider in turbulence and extreme situations. This puts the Astral 2 at the bottom end of the DHV 2 class. Diagonal ribs (cross tapes) over three cells on the Astral 2 without line attachments results in increased performance in all respects. In addition, a 5 riser system and split A´s allows a most efficient speed system (excellent glide at speed with maximum stability) and split A´s makes the glider extremely user friendly.

The Astral 2 is the most stable accelerated glider Swing has ever produced. The lines are now Betech for the best possible quality. The main reason for this change is better characteristics in overall performance and stability, particularly regarding its resistance to stretch. A 3-year/300 flight hours guarantee is offered by Swing.

The Swing Astral is aimed at pilots who want top performance from their wing but still retain the pure flying fun and uncomplicated handling. The Astral is fitted with V-tapes, and the number of cells, the line geometry and profile place the Astral very close to our performance wing Ventus. An extremely easy glider to launch combined with a very direct handling, the Astral is very stable in flight and has a large speed range.

The Astral 3 was intended for all pilots, ranging from the motivated social pilot to the serious but safety-conscious. As performance is concerned, the Astral 3 is positioned at the top of the intermediate gliders.

The Astral 3 is the first product from the design and development team of Michael Hartmann and Dr. Stefan Müller. The simulation software used to develop this wing is unique in the paraglider business and attention can be directed to distortions in the canopy right from the paraglider's development phase.

Following intensive development work, a new combination of materials is used on the Astral 3 for the first time.
It uses a 44 g/m light nylon fabric with a special silicone and polyurethane coating from Perseverance for the top surface. WT 7 from Toray I is used for the bottom surface. This combination of materials allows moisture to escape from the inside of the paraglider by diffusion, despite a good porosity reading for the top surface.

Compared with its predecessor, the Astral 3 has improved thermic flight characteristics and new, very direct handling where there is low control pressure. The precise, defined handling allows gentle turning in weak thermic conditions and easy turns with good banking in strong conditions.

The Astral 4 is the third coup for Swing's test team made up of Michael Hartmann, Manuel Croci and Christian Amon. The successful concept of the Mistral 3 was further developed and optimised for a DHV-2 glider as the Astral 4.

The Astral 4's can be stabilised very easily in turbulent conditions, it has almost no tendency to shoot forward and can be precisely centred in thermals. After it has begun to turn, it follows the desired path with precision.

On launch, the glider can be steered very well and it rises evenly above the pilot even in difficult conditions, and there is little tendency to overshoot.

The top surface of the Astral 4 is made from a highly UV resistant double-layer siliconised fabric, cell construction is from diagonal segments, and a system of load-bearing tapes in the bottom surface help the wing to maintain its profile. The load-bearing tapes allow ideal energy transfer from the lines to the wing, so as to avoid unnecessary hesitation and wrinkling in the bottom surface.

The canopy has 57 cells and an aspect ratio of 5.55. The design allows the lines to be reduced to two levels, i.e. main lines and top lines which reduces the overall resistance of the wing and increases glide performance.

Swing presented the Astral 5 in the sport class (up to DHV 2) and features an aspect ratio of 5.7, with direct and well-balanced handling, it uses the same profile as the Stratus 7 competition glider. The Astral 5 was in production in 2008.

The Astral 6 intermediate has an aspect ratio of 6.4 and a very impressive glide angle. At all times, the Astral 6 progresses comfortably and reliably and minimal steering adjustment is needed to maintain the desired bank angle.

High Arc Technology (high aspect ratio with strong canopy curvature) was successfully transferred from the competition scene to an intermediate glider. In addition to the measurable performance and aeronautical advantages, it gives the Astral 6 its distinctive and elegant high-performance appearance. The new HAT concept allowed Michael Hartmann’s development team not only to make it as ideal as possible for competition and XC, but also to satisfy all LTF 2 manoeuvres.

The Astral 6 featrew Flex Sticks: lightweight leading edge reinforcements with high form stability. The use of lighter materials has reduced the canopy weight to just 5.6kg for a size 24 glider, and yet it has 57 cells. The Riser – completely reworked, new shackle form, and brake handle – with soft neoprene cover and four possible levels of stiffness plus swivel.
