Wing
Area Problems
If so instructed by your teacher, print out a worksheet
page for these problems.
 Using the picture
and dimensions provided, calculate the area of the Wright Brothers wing
section and the F18 Blue Angels wing. Record your answers in the data
table.
 Open the
FoilSim
program. Set your airspeed =100, altitude =2,500, angle=5.0, thickness
=12.5, and camber=0. Change the area by plugging in the values you calculated
for each wing area and record the resulting lift force in your data
table.
 Graph your results
with the calculated values for area on the xaxis and the lift force
on the yaxis. (Be sure to label your graph.)
 What is the relationship
suggested by this graph?
 Find and record
the slope of your graph.
 Using the calculated
slope, write the equation for the line (on your graph) using the form
L = Constant * A, where L is the lift, constant is the slope,
and A is the area.
 Using your equation,
calculate the lift produced by the Boeing 747 and Concorde (area
given in table). Record your answers in the table.
 Using your equation,
calculate the area of the Space Shuttle compound wing (lift given
in table). Record your answer in the table.
 Design a trapezoid
wing that will generate a lift force of 121,000 lbs. Your wing span
(distance from wing tip to wing tip) may not exceed 95 feet.
