Aerodynamics Analysis of F-16 Aircraft
... When consider the normal shape of the graphs we could see same change in graph of Figure 9. The value at zero angle of attack is little bit stationary and it is because for lower angles of attack the flow will not separate much over the airfoil. But when the angle of attack increases the flow will s ...

Blade Element Theory for Rotor in Hover and Climb
... Blade element theory is similar to the strip theory in fixed wing aerodynamics. The blade is assumed to be made of several infinitesimal strips of width ‘dr’ . The lift and drag are estimated at the strip using 2-D airfoil characteristics of the airfoil at that strip, and what we know about the loca ...

... The lift force is thus forced to be proportional to V and not to V2 as assumed by R&R. This proportionality can also be derived using Bernoulli`s equation for a flow like that pictured in figure 1 in the paper by R&R. The flow in a not rotating frame of reference following the sphere is assumed to b ...

Effect of Weight on Drag and Airplane Performance

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) refers to forces acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity.Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity.Drag forces always decrease fluid velocity relative to the solid object in the fluid's path.
