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.

- 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.
