WebNov 3, 2015 · Parasite drag is simply caused by the aircraft's shape, construction-type, and material. For instance, an airplane with a rough surface creates more parasite drag than one with a smooth surface. … WebSep 28, 2024 · The lift coefficient is increased by increasing the angle of attack of the wing or changing the wing curvature by deploying flaps like you see during landing. You will also notice that the magnitude of the lift-induced drag is inversely proportional to the aspect ratio. Therefore as the aspect ratio increases, so the lift induced drag decreases. bmtcs8006.jxgd.mtc.local/redmine

The lifting part is called the induced drag coefficient or, more generally, “drag due to lift,” and it can be seen that this value depends significantly on the wing’s operating lift coefficient. bmtc school 3

"WebNov 7, 2024 · The drag coefficient due to non-lift-dependent drag CD0 (that is friction, parasite, trim, everything but induced drag) is Cdtot minus Cdi So that’s 0.0203 minus 0.0017 which is 0.0186. Which can be used to check the ratio of lift and non-lift drag at the given speed. Normally Cdi will be less than 10% of CD0. " - Parasitic drag coefficient
