contestada

an airplane weighing 5500 lb is flying straight and level at msl with a velocity of 220 mi/h. at this velocity the l/d ratio is a maximum. the wing area and aspect ratio are 200 ft2 and 8.5, respectively. the oswald efficiency factor is 0.93. calculate the total drag on the airplane.

Respuesta :

The total drag on the airplane is 97.28

define velocity?

Velocity is the rate of change in position of an object in motion as measured by a certain time standard (e.g., 60 km/h northbound). Velocity is a key notion in kinematics, the branch of classical mechanics that studies body motion.

weight of plane=5500lb

velocity=220m/h

=200x88/60

=292

wing area= 200 ft^2

aspect ratio=8.5

oswald efficiency (E)=0.93

density of air = 1.225Kg/m^3

=0.002377

Drag= 0.5xpxvxAxcd

lift coefficient=0.245

drag coefficient= 0.0024

cd=0.0024+0.0024=0.0048

drag= 0.5x0.002377x(292x292)x200x0.0048

=0.0011885x(85264)x200x0.0048

=97.28 lb

therefore the  total drag on the airplane was 97.28 lb
