The following outline is a suggested activity for teachers to use with their students.
LIFT of
an airplane is a function of several variables, among them wing area..
This activity allows students to use measurement, simple ratios, and simple geometry to find the wing area for any plane
chosen from the Plane Gallery. The twelve aircraft in this Gallery
were all photographed from scale models with the scale 1:72.
Given the scale in the picture, the scale of the model, and the actual wingspan, the challenge for the student is to find to wing area of the model and the wing area of the actual plane. (Groups can be assigned to work on different planes.)
Double the result for the total wing area. This is the area used in the "FoilSim" program that calculates the LIFT for that chosen aircraft. Compare the results of your calculations with the Linear Data Sheet. Check units of measure.
