Stabilo-Line-Security-Function

A further innovation concerns the repair of 

cravattes. Even best pilots are not protected 

against cravattes, for example if they train new 

fi gures or exiting  Choreographies.  

So far most cravattes end at the rescue

 parachute. Because of the high acceleration 

forces in dynamic fl ying, which constantly rise 

with less surface size of the glider. For a pilot, 

who is exposed to these high g-forces, it is not 

dependent on pilot skills and training condi-

tions to fi nd quickly the stabilo line. Th

  e repair 

of the cravatte actually is mostly not a prob-

lem, the challenge is in fast fi nding and the 

Stabilo line. With the „Stabilo LINE Security 

Function“ becomes now substantially simpler: 

Th

  e SLSF is a pulley, by which the Stabilo line 

is pulled and fastened with a rubber line to the 

B-Riser. When getting a cravatte the pilot can 

pull so the Stabilo line by grabbing and pull 

the loose rubber line and open the cravatte.   

High Pressure Crossport Design (HPCD) 

Crossports are of decisive importance for the cross ventilation of a paraglider, as only a wing with 
suffi

  cient internal pressure can shape the profi le optimally. With the High Pressure Crossport De-

sign HPCD), U-Turn has created the perfect conditions to ensure the ideal internal pressure in the 
canopy. During extensive test fl ights we have mainly ascertained that: 1. Th

  e infl ation of the canopy 

and therefore the setup of impact pressure can be considerably optimized by means of diff erentia-
ted crossports. 2. Th

  e eff ect of unintentional defl ation in ambitioned angles of attack or thermally 

demanding conditions can be moderated and controlled. At the same time the level of control com-
mands increases, generelly the feedback of the canopy becomes better. Handle, master.
Th

  erefore, in order to optimize the cross ventilation in the canopy, U-Turn is using crossports of dif-

ferent sizes and diff erent cross section. Diff erent levels of pressure come up in the paraglider. 
In accordance with the physical laws, they are constantly compensating each other in a quick se-
quence. Th

  e individually diff erentiated crossports have two eff ects: On the one hand, the tendency 

to unintentional discharge process is enabled by increased air inlet. Both steps are important for the 
stability of the wing.
Crossports in the modern U-Turn wings diff er depending on whether the cells, where they are inte-
grated, have line contact points or not. Depending on the calcualtion values, the openings are made 
larger or smaller - and also the shape of the openings varies from round to oval.

Where as the focus of the HPCD functionality for more powerful wings is on better stability against 
folding, clear feedback and better control, the category 1 paragliders from U-Turn have as particular 
design objective the minimized surging tendency.
