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.
