Airfoils are designed so that the flow over the top surface ... Therefore, to find the velocity V_e, we need to know the density of air, and the pressure difference (p_0 - p_e). The density can be ...

Humanity has long been obsessed with heavier-than-air flight ... starting with how it is linked with the pressure distribution around airfoils. We also cover a few different explanations of ...

The rounded profile of a bird’s wing creates an airfoil, which generates lift and ... Briefly put, the flapping of their forewings creates a low-pressure vortex above the wings, and their ...
