Specifications Problems
If so instructed by your teacher, print out a worksheet page for these
problems.
Use the program
FoilSim
to answer the following questions:
 Design an airfoil
(wing) that can supply at least 15,000 lbs. of lift at an altitude of
40,000 ft. with a minimum airspeed of 230 mph.
Airfoil Data:

230 mph

40,000
ft.






 Using graph paper,
plot the pressure of the air as a function of (versus) the altitude.
 What does this
graph tell you about the relationship between the air pressure and the
altitude?
 Using graph paper,
plot the temperature of the air as a function of (versus) the altitude.
 What does this
graph tell you about the relationship between the air temperature and
the altitude?
 Design an airfoil
that maximizes lift but minimizes the wing area at an airspeed of 230
mph.
