Area Answers
 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. See table shown below.
 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. See table shown below.
 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.) The
graph will be a straight line through the origin.
 What is the relationship
suggested by this graph? This indicates
a directly proportional relationship.
 Find and record
the slope of your graph. The calculated
slope is approximately 14.
 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. L=14A
 Using your equation,
calculate the lift produced by the Boeing 747 and Concorde (area
given in table). Record your answers in the table. See
table shown below.
 Using your equation,
calculate the area of the Space Shuttle compound wing (lift given
in table). Record your answer in the table. See
table shown below.
 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. Answers
will vary. The design wing should not exceed an area of 8643 sq. ft.
FoilSim will accept only whole values for wing area and will round the
answer.
