This examination paper may be taken from the examination room. Answer ai_l two (2) questions: [12. 5 marks] the wing of a light aircraft of 1,440 kg gross weight has the following characteristics: Naca 651-212 a=0. 6 airfoil (see page 2 for airfoil data) The aircraft cruise speed at 3,000 ft altitude (~= 1. 76x10-5 kg/m/s) is 200 km/h. The loading on the wing may be assumed to be elliptic. Determine: lift coefficient, profile drag coefficient and induced drag coefficients at cruise. [3. 5 marks] the flaps up stall speed at 3,000 ft. [2 marks] the sea-level stall speed with the split flaps deflected to 60 deg. [2 marks] the induced angle of attack and induced velocity in cruise condition.
