• ## An airplane is cruising at $$50\,m/s$$ at standard sea level in straight and level flight. The airplane has a wing area of $$15\,m^2$$ and a wing span of $$10\,m$$, and has the maximum gross weight of $$1000\,kg$$. The airfoil of the wing has lift slope of $$0.102$$ per degree and angle of attack at zero lift of $$-2.5^{\circ}$$. Considering, $$\tau = 0.1$$, find the angle of attack for the wing. Also, find the induced drag for the airplane, if span efficiency factor is $$0.6$$.

• ## A finite wing has aspect ratio of $$6$$ and taper ratio of $$0.8$$. The airfoil constituting this wing has a lift slope of $$0.102$$ per degree, and angle of attack at zero lift of $$-1.2^{\circ}$$. Assuming that $$\delta =\tau$$ and equals approximately $$0.03$$ , find the coefficient of lift and induced drag coefficients for this wing at an angle of attack of $$6^{\circ}$$.
