The AirDesign DONUT rescue system combines the positive characteristics from both square
and annular (round) rescues. The DONUT is cut like a square canopy, but in the air presents
more like that of a traditional annular. As a result, packing is still as simple as with conventional
round rescue systems.
The DONUT’s revolutionary design provides fast opening times. Its four centre lines create a
higher projected surface, resulting in low sink values. Side vents make the rescue oscillation
stable. Aside from fast open time, stability and low descent rates, the other main factor in
pilot’s minds when considering reserve options is weight. As a result, you’ll be quietly pleased
to know that we have designed and manufactured the new DONUT with lightweight materials.
In many drop-tests we simulated real-life flight behaviour. The DONUT maintains its
demonstrated safe and stable characteristics, even after repetitive tests and water landings.
Summary:
• Fast opening
• Low oscillation, high stability
• Low sink rate
• S imple packing
• Low weight
• Exceptional live test results
