Explain what effect an increase in airspeed has on lift, as well as on drag, both induced and parasite - Essay display caseThis equation is derived from Newtons second law of motion whereby the net force on an object is equal to its rate of momentum change (Dole and Lewis, 2000). Thus, as air flow increases crossways an airfoil section, the rate of change of momentum is increased across the upper areas of the wing section, increasing lift (Dole and Lewis, 2000). Bernoullis belief states, an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. This is seen in the equation Pressure+1/2 density(rho) V2= unvaried Noting that Bernoullis equation above is used for non compressible flows (low mach numbers) (FAA, 2001), the equation shows that as velocity increases, if the equation is to remain balanced, pressure must decrease. Thus, as airflow increases across the upper surface of a wing due to speed, lift is increased due to the drop in pressure above the wing. Drag is derived from Newtons third law whereby, for every action there is an equal and antonym reaction (Dole and Lewis, 2000). The action of the airfoil section on the incident airflow creates an opposite reaction, drag. Drag increases as speed increases (FAA, 2001). This is seen in the equation Drag = Cd x(1/2 pV2) x area, where Cd is the coefficient of drag.
