STALLING A RAM-AIR

Ram-Air wings stall just like rigid wings.

Angle of attack is adjusted my using the toggles, which connect to the trailing edge of the wing. I've stalled the parachute here, a Falcon-170 (wl-1.17:1), by holding both toggles down as far as I could. In a steady-state stall the angle of attack reaches nearly 90-degrees before stalling. Once stalled, the AoA increases to 90-degrees and air deflected from the drooped trailing edge causes the parachute to collapse.

The descent rate at this moment is slowed purely by drag like a round parachute. Because ram-air parachutes have much smaller dimensions than round parachutes, this is NOT a landable condition.
