An aircraft has an untwisted wing with an elliptical planform. The wing generates an elliptical spanwise lift distribution. The aspect ratio is 7.9 and the wing span is 15 m. The wing loading (i.e. lift per unit length) is 0.7 kN/m. If the aircraft is flying at sea level at a speed of 38 m/s.calculate the induced drag force in Newtons.
