After 9 deg., the lift curve slope changes with increasing AOA. Eventually, ... In Part 2, we’ll discuss leading-edge stall. Patrick Veillette, Ph.D.

In this month’s How It Works, we look at the leading-edge wing cuff, a relatively simple concept designed to improve stall-spin resistance and take a bite out of GA accident numbers.

Despite their advantages, adding bionic flaps can also reduce lift, particularly before a stall sets in. Therefore, the investigators tried an approach combining Gurney flaps with bionic features.

These leading edge slats provide the lift necessary at low speeds, ... The droop nose design concept also sees the skin on the front edge of the wing curved, ...

An airfoil that exhibits classic leading-edge stall behavior, such as the NACA 4412, has little or no rounding of the lift curve near maximum lift. The lift coefficient exhibits an abrupt loss of ...
