(25 marks) A jet aircraft has the following dat =80000NS=35m^(2),
C_(D)=0.025+0.05C_(L)^(2),C_(D)=0.025+0.05C_(L)^(2),c=1.6s^(0.2)(N)/(N)h,W_(f)=30000Ns=0.6 30(m)/(s) during the range.
At sea level: r_(0)=1.225k(g)/(m^(3))
(15 marks) Show that for SST, the lift-to-drag ratios is given by
E=(2znE_(m))/((1+n^(2)z^(2)))
