Pilot Interview Question:

What sources are involved in aerodynamics?

Submitted by: Administrator

There are two sources that are involved in the case of aerodynamics forces and moments that are on the body. These forces are as follows:
► Pressure distribution:
This is the distribution that is over the body surface
► Shear stress distribution:
This is the distribution that is over the body surface
These sources are for the body shapes and it doesn't matter how complex they are. The mechanism that is being used to communicate with the bodies that is moving through a fluid. Both the pressure (p) and shear stress (?) having the dimension force per unit area. This helps the movement of the body through the fluid.
