Just like any other airfoil.
circular arc is a segment of the circumference of a circle
The radius is the distance between the centre of a circular arc and a point on the arc.
no it wont work because it has to be symmetrical
No. The air flow path across the top of the airfoil must be longer than the path below.
If the arc is circular, such a figure is a semicircle or half circle.
As long as the arc isnt a full circle, just 1, if it is a circle, infinite.
The area bounded by an arc of circle and two radii is known as a "circular sector"
An airfoil typically consists of a leading edge, a trailing edge, an upper surface, and a lower surface. These parts work together to generate lift as air flows over the airfoil, allowing an aircraft to stay aloft.
It is the distance around an outside of a round 180 circular object
A part of a circle (the area) bounded by an arc and a chord is termed a circular segment. A link can be found below.
the ground is an type of airfoil
It depends on what the airfoil is made of.
