A light aircraft is flying at a speed of 60 m/s in ISA conditions for an altitude of 2000 m. The aircraft has a mass of 750 kg and a rectangular planform (zero sweep) wing of 15 m² area, 9 m span and 160 mm thickness. Due to the fuselage, 85% of the wing is exposed to the air. A 20% increment should be applied to the friction factor to account for wing surface roughness. u= 1.750 x10 kg/ms. Calculate the skin friction drag coefficient for the wing. Keep 5 decimals. Question 18 An aircraft has a wing area of 70 m2 and a wing loading of 2500 N/m?. The air density could be taken as 0.45 kg/m3. The drag equation for the aircraft is given as: Cp=0.016+0.055 C? Calculate its minimum drag speed in m/s. Keep 2 decimals. A light aircraft is flying at a speed of 60 m/s in ISA conditions for an altitude of 2000 m.
