Main Question or Discussion Point
The forces acting on the glider are the gravitational force, the lift force and the drag (air friction).
The drag () and lift force () are a function of the angle that the wings have with the gliding direction. =122 with: =0.1+3∙10−32
=122 with: =0.2+0.1− 3∙10−32
In the above equations, is in decimal degrees. Calculate and plot the travelled ground distance as a function of the gliding angle .
The gliding angle is the angle of the gliding direction with respect to the ground (see figure 1).
Note that the angle is determined by the wing angle .
What is the optimum wing angle and corresponding travelled maximum distance?
