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 F-18 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 x-axis and the lift force
on the y-axis. (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.
