A decade of OSP1 Feedback
The OSP1, originally released in 2007 redefined the BASE canopy market with numerous revolutionary features to improve the opening and flight characteristics - known for its reliable fast openings, precise control, unparalleled deep brake handling and powerful flare. Now it is time for an update incorporating the latest design innovations, the OSP2.
OSP2 is an all-round BASE canopy that brings joy to slider up and excels for slider down. (slow slider recommended for terminal jumps).
Improved Glide
We have refreshed the design retaining all the great features of the original OSP whilst improving the performance envelope.
The OSP2 has a similar horizontal speed as the original OSP and improved glide.
As standard the OSP2 retains the MDV5 , ZP leading edge with SLATS and mini stabilizers from the OSP1.
Better Performance
The ZP leading edge design has been improved using the same split panel technique as seen on the Vision, reducing the sink rate and increasing performance.
The bridle attachment point is moved further back, so that the tension from the PC is applied to all the lines during opening, instead of just the AB lines, this improves the behavior of the deploying canopy and helps reduce the chance of tension knots.
Fine Tuning
The tail pocket design has been improved to reduce weight. The brake lines are now continuous without loops at the cascades and this also helps reduce the risk of tension knots.
The brake settings are now made from Spectra insert loops to improve durability, helping the lower brake lines to last longer.
We have added 3 additional sizes 235, 255 and 275 as many pilots found themselves exactly between 2 sizes.
OSP2 canopy can be ordered in either F111 or PN9 lightweight material. As standard, the OSP2 is equipped with white, or at extra cost, black Dacron lines. Center tail gate and brake lines are made in red colour. We also offer the »Black option« where all reinforcement tapes and thread are in black colour as well as the OSP2 logo on the outer rib. As standard the canopy is equipped with rapid links or optional soft links.
MDV - Mono Directional Valve
Atair has always been at the cutting edge of parachute design and technology, as demonstrated with the introduction of numerous innovations such as the Mono Directional Valve (MDV) technology. MDV is a unique design that allows the air to flow into the canopy via bottom skin vents during the deployment stage and also during deep brake descent. In normal flight, the vents stay closed and do not disturb the internal airflow inside the canopy.
A canopy with MDV offers additional performance by increasing the canopy flight envelope in deep brakes, before reaching the stall. The canopy still has a great flare when equipped with MDV. When making a jump with the slider up, the canopy will inflate a bit faster than normal, but the true benefits of MDV technology are fully exploited on slider down jumps. The Atair MDV system also has a very low packing volume. During deployment, MDV technology provides superior canopy pressurization, reducing the amount of altitude required for canopy inflation and allowing the jumper almost immediate control of the canopy.
SLAT System
The SLAT system is used to increase the maximum lift coefficient and reduce stall speed. Slats are small leading edge airfoil extensions that are forming a slot at the first 10% of the leading edge. Part of the air that is entering the cell is directed through the slot back to the upper side of the canopy, speeding up the airflow and resulting in delayed separation of the airflow, allowing the canopy to maintain lift at lower speeds and a higher angle of attack before reaching the stall, and also reducing vertical speed. The SLATs are applied to the leading edge of cells #3, #4 and #5, because on rectangular platform wings, the stall occurs first at the middle of the span, i.e. on the center cells.
