Wingtip Feathers Increase Aerodynamic Efficiency — …

 · Wingtip feathers in birds are aerodynamically efficient because of their torsional flexibility. The three birds are shown in different types of flight. The middle is in the downstroke, and its primary flight feathers are positioned to get the full lift. The on the left.

Aerodynamic Lift

Conversely as the angle of inclination decreases, the lift increases and the drag decreases; however, as the angle of inclination is reduced so does the resultant reaction force. If an aerofoil profile is used instead of the flat plate, (see Fig. 14.24(a and b) ), the airstream over the top surface now has to move further and faster than the underneath air movement.

Lift and Drag Force

 · Lift is perpendicular to relative airflow or flight path or drag. There are two types of lift: Positive lift ( acts upward ) Negative lift ( acts downward ) If we consider an aeroplane which have positive lift. The governing equation for lift L = ( 1 /2 ) ρ V 2 S C L Where C L 3).

Lift and Drag

Recall from Bernoulli's equation and continuity equation the faster the velocity of a fluid the lower the pressure and vise versa. As with drag, a lift coefficient can be used to determine the lift force; refer to equation 1. (Eq 1) $C_L=frac{L}{frac{1}{2}ρU^2A}$ C L.

Wind Energy

Wind turbine technologies have evolved over centuries from traditional wind mills to the slick turbines we know today. Developing a wind turbine requires a number of design decisions, starting from the axis orientation, and number of blades to choice of material. Over the years, a dominant design has emerged, which consists of 3 blades, mostly.
