WebJun 10, 2024 · Some wetted area estimates depending on the aircraft class are given in Raymer . However, no data for UAVs is available. ... Wing, tail, fuselage, and tailboom only contribute between 40 and 64% of the total parasitic drag share, despite having about 90% of the entire airframe wetted area. Tailboom drag is rather small and does not exceed … WebThis then becomes 3.88 / 174 = 0.0223, being the drag coefficient for the fuselage based on gross wing area. We can also estimate the wetted surface area based on the Hoerner analysis, where the areas will be in inverse ration to the drag coefficients. Using his drag coefficients, Cd = 0.009 based on wetted surface area (to be found) Cd = 0.032 ...

WebMay 30, 2007 · Since the A358 wing area is 442 sq. m and the 789's appears to be 368, the wetted area drag of the A358 wing is about 20% higher than the 789. Since wing wetted area ranges between 30% and 40% of total wetted area, this means the 789 has a 6% to 8% advantage in wetted area drag and by extension, a 6% to 8% advantage in zero lift … WebSep 28, 2024 · The fuselage slenderness ratio (ratio of length-to-diameter).
