Considering the characteristics of large slenderness ratio structure, it is reasonable to simplify the dynamics of a HALE aircraft as the plunge, pitch, and flap motions of a planar airfoil. The ...

Airfoils work because the higher speed of air going over the top surface results in lower air pressure than the slower air beneath. If you drilled a hole top to bottom in an airfoil, which direction ...

Illustration of the airflow along an airfoil that exhibits leading-edge stall behavior. Notice the formation of a “short bubble” at a critical point along the leading edge. When the AOA is increased ...

The multiple lifting line method LIFTING_LINE is a potential-flow-theory based program, which computes the aerodynamic coefficients of a given configuration consisting of one or more nearly ...
