Higher aspect ratio wings result in a lower lift-induced drag coefficient. Weba constant propeller efficiency, and therefore a constant available power value. The general dimensions of the aircraft is given in the three-view in Figure 1. For the parasitic drag calculation, a field trip was made to University Airport to obtain the dimensions of the external aircraft

Engineering:Oswald efficiency number - HandWiki

WebFor conventional fixed-wing aircraft with moderate aspect ratio and sweep, Oswald efficiency number with wing flaps retracted is typically between 0.7 and 0.85. At supersonic speeds, Oswald efficiency number decreases substantially. For example, at Mach 1.2 Oswald efficiency number is likely to be between 0.3 and 0.5. WebThe characteristics of the airplane are as follows: aspect ratio = 6.2, wing area = 181 f t 2, Oswald efficiency factor = 0.91, weight = 3000 l b, and zero-lift drag coefficient = 0.027. The airplane is powered by a. single piston engine of 345 h p … challenger diamond plate tool box

WebMay 2, 2015 · Note that you do not need the planform efficiency (Oswald factor) $\epsilon$ for calculating lift curve slope. That only comes into play when you compute the induced drag of the wing.
