About the U-TURN JOKER

 

The JOKER redefines the rules of the game – the principle of pure dynamics brings uncompromising extra power with high rotation speed back to the paragliding acrobatics. Once again, it is about a new touchstone. The professional wing combines performance-oriented dynamics with supremely precise handling - „All it takes is a little push“. The JOKER overrides the laws and keeps up the high pressure in the canopy between manoeuvres. Responsible for that are the valves in the bottom sail (PBV), developed by U-Turn, in combination with the pressure-optimized geometry of the leading edge. Despite the high dynamics, the JOKER has a balanced canopy harmony, so the reactions are accordingly soft as well.

The wing performs all acro-manoeuvres very swiftly and especially scores regarding the connections. Through the glider's high dynamics and fantastic turning characteristics, all manoeuvres can be exactly led over to and combined. The response behaviour is direct and very precise. Nevertheless, the wing is condoning if the dimming is slightly off. The compact wing has high internal pressure with minimal control delay and still delivers gentle feedback. The pressure at the stabilos was significantly improved multiple times, creating the base for the outstanding turning features at all negative manoeuvres. The exceptional athlete and Acro-Team pilot Brooke Whatnall was in charge of the development and took care of the elaborate trimming of every size over the course of one year. At this place, we would also like to thank the countless Joker test pilots who voiced their feedback in Organyá and contributed to the perfection of this acro wing. The JOKER is optimized for Twisted Tricks. Therefore, trimmers were left off the risers to keep them clean.

Innovations

Acro constructer legend Ernst Strobl trusts in the U-Turn typical High-Tech design of the leading edge with pressure-optimized opening sizes and the reinforced Precision Profile Nose (PPN) to optimize the flow-around at the nose area. The PPN+ additionally holds the individual cells in shape and ensures the air income through the rods that are worked in in the middle of the openings - in combination with the valves in the bottom sail that‘s ato resolve problems caused by swaying movements quickly pure dynamic weapon. The additional aeration through the Pressure Balance Valves (PBV) in the bottom sail is an innovation by U-Turn. Through the PBV, the wing is provided with the necessary pressure, even in extreme angles of attack in aerobatics. The High-Pressure Crossport Design (HPCD) optimized the lateral aeration and provides a balanced internal pressure for the glider. All line attachment points are multiply reinforced. Like all U-Turn Acro gliders, the JOKER is equipped with the Stabilo Security Function (SSF) to quickly resolve problems caused by swaying movements.

Material

The JOKER is built of very high quality and designed for long durability under extreme loads. The numerous innovations and reinforcements call for a very elaborate production process. At the JOKER U-Turn also trusts in the newest generation of the refined version of the Thriller-fabric PX40. Only materials which passed extensive long-term tests and have shown good values were used in the JOKER. But also, in the processing, everything is done to ensure long durability and form fidelity, which includes multiply reinforced sewings and reinforcements at the line attachment points and V-tapes. The line connections are equipped with Line Loop Protection (LLP). Thereby the Kevlar core is spliced into the connection loop, which prevents snagging of the lines at the point of separation.
