Question
For jet aircraft the range parameter R, is defined as:
2
Rp
=
V L
-
C; D
Show that the speed at which the range parameter reaches its maximum value can
be expressed as
2W 3K
VRpmax
=
where K =
ps Cdo
пае
V
During the cruise condition you may assume that the specific fuel
Consumption C; remains constant. What are the corresponding expressions
for the lift and drag coefficients? What should be the lift to drag ratio during
the cruise at 35000 ft in order to achieve Rpmax? For this segment of the flight,
you may assume that the Oswald efficiency is equal to 0.85.
