Trailing edge

Elevators and ailerons may be combined as elevons on tailless aircraft.

A sharp trailing edge is always employed in an airfoil.

[3] George Batchelor has written about: Other sharp-edged surfaces that are attached to the trailing edges of wings or control surfaces include: Other equipment that may be attached to the trailing edges of wings include: The trailing edge is where the upper and lower surfaces of a wing meet.

The angle between the upper and lower surfaces at the trailing edge is called the trailing edge angle.

[5] In two-dimensional flow around a uniform wing of infinite span, the slope of the lift curve is determined primarily by the trailing edge angle.
