Use 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:

**Airspeed****Altitude****Angle****Thickness****Camber****Area****Lift****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
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
air temperature and the altitude?
- Design an airfoil that maximizes lift but minimizes the wing
area at an airspeed of 230 mph.
Airfoil Data:

**Airspeed****Altitude****Angle****Thickness****Camber****Area****Lift****230 mph**

- Design an airfoil that maximizes lift but minimizes the wing
angle at an airspeed of 230 mph.
Airfoil Data:

**Airspeed****Altitude****Angle****Thickness****Camber****Area****Lift****230 mph**

- Design an airfoil that maximizes lift and altitude at an
airspeed of 230 mph.
Airfoil Data:

**Airspeed****Altitude****Angle****Thickness****Camber****Area****Lift****230 mph**

- How does the lift depend on airspeed?
- How does the lift depend on altitude?
- How does the lift depend on wing angle?
- How does the lift depend on wing thickness?
- How does the lift depend on wing camber?
