Troll Canopy´s     Troll Canopy ´s EUR 1,440.00 Troll Base Canopy ; starting at 1440 Euro!TROLL DW Atair aerodynamics who make the renowned Troll base canopy. The Troll is a low aspect ratio 7-cell canopy that is built with the highest quality materials and is heavily reinforced in crucial high load areas such as bridle attachment points and suspension lines. This enables it to withstand the heavy demands of modern day BASE-jumping. The Troll’s unique aerofoil is slightly tapered on the upper surface. This makes for a more efficient wing with less drag. All Troll canopies have Dacron lines, a unique tail pocket design that allow the lines to be securely stowed. All Troll canopies are made of F111 fabric. Troll canopies are available with or without MDV technology, the choice depends on what kind of jumps you plan on doing ( see MDV section) The profile of the Troll allows comfortable openings, great canopy rides and precision landings. A great match for an Adrenalin container. Standard with Troll * Tail pocket * 2 brakes setting * Control and Tail Gate lines in different color * Big mesh slider * Tail Gate (BR) * Black lines option MDV System Atair aerodynamics is on the cutting edge of parachute design in general and this has become very clear with the introduction of MDV technology. The valve system on the Troll is called Mono Directional Valve technology or MDV technology. It is unique in that it is a zero-p tubular shaped funnel that is about 6" long. They are attached to mesh inlets on ribs 2, 3,4, 5 & 6. This design allows the air to flow in during pressurization and also during deep brake decent, the valve closes when air is rushing in from the nose and avoids back pressure coming from the tail. The Troll in its standard form is already a very stable canopy. The MDV Troll only offers more stability by increasing the range in which you can fly in deep brakes before you actually reach the stall point. The canopy has a great flare in both its standard form and with the MDV technology. As far as openings go... although the MDV inlets have increased the speed in which the canopy pressurizes slider up as well as slider down. Obviously, the true benefits of having inlets are for slider down jumps. Slider down, it offers single stage pressurization and slider up it opens a bit faster than the standard Troll. If you are going to do many terminal jumps at a given time, it is advisable to switch sliders to a marquisette mesh (small hole mesh slider). This helps take the edge off of the opening without compromising consistency. Sail sliders have been know to cause opening/heading inconsistencies on BASE jumps and we don't advise their usage. MDV technology offers superior pressurization; giving the jumper control over the canopy immediately. Control = Confidence! Canopy size Picking the right canopy size is very important. The recommended weights apply for normal use only. If you jump at in the mountains or perform jumps with difficult landing areas, we recommend you stay in the lower range, close to the minium recommended weight. Weight = jumper with clothes and shoes * 185 min 55kg max 65kg * 205 min 60kg max 70kg * 225 min 67 kg max 77 kg * 245 min 73 kg max 83 kg * 265 min 79 kg max 89 kg * 285 min 86kg max 96kg * 305 min 92kg max 102 kg [Add to Cart]  [View Cart]     OSP The New Canopy Ready to Order EUR 1,700.00 Atair is proud to introduce the OSP Slider Down BASE canopy, its design is *O*ptimized for *S*lider down *P*erformance. The canopy utilizes a revolutionary new leading edge slat technology to keep the air flow over the canopy attached even during very steep deep brake approaches. The OSP also incorporates a new thicker profile to further improve deep brake flying characteristics as well as a shorter line set to promote faster openings and better on-heading performance. The OSP design also has the advantage of reducing the forward speed of the canopy after opening which helps object avoidance in the case of an off heading opening. A steeper descent on the order of one to one is desirable as for slider down jumps the landing area is generally underneath or close to the object. Thus not only is a low forward speed beneficial, but a low descent rate also. The canopy profile of the OSP has been specially selected to enable steep landing approaches, generating high lift even when the flow is partially separated. The maximum lift coefficient is further increased through the use of a SLOT formed by a leading - edge auxiliary airfoil called a SLAT. The first 10 % of the leading-edge is made of ZP fabric which covers the leading edge of the canopy and creates the slot. The air flows from inside of the canopy through the slot and over the airfoil. This results in a delay of airflow separation. Use of the SLAT allows the airfoil to be flown at a higher angle of attack before stall will occur and thus achieves a higher maximum lift coefficient . The SLATs are applied to the leading edge of cells #3, #4 and #5, because rectangular wings stall in the middle first. The OSP is intended for slider down and sub-terminal slider up jumps (ideally for 5 to 8sec delay slider up). Jumping the OSP for full terminal jumps is possible but not recommended as the openings may become uncomfortable. [Add to Cart]  [View Cart]
