Wing Specifications Answers


  1. 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.






    Answers will vary.

  2. Using graph paper, plot the pressure of the air as a function of (versus) the altitude.

     Students will make a graph.

  3. What does this graph tell you about the relationship between air pressure and the altitude?

     The graph will show that pressure decreases as altitude increases. 

  4. Using graph paper, plot the temperature of the air as a function of (versus) the altitude.

     Students will make a graph.

  5. What does this graph tell you about the relationship between air temperature and the altitude?

    The graph will show that temperature decreases as altitude increases.  

  6. 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






    Answers will vary.

  7. 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






     Answers will vary.

  8. Design an airfoil that maximizes lift and altitude at an airspeed of 230 mph.

    Airfoil Data:

    Airspeed
    Altitude
    Angle
    Thickness
    Camber
    Area

    Answers will vary.

  9. How does the lift depend on airspeed?

    Lift increases with airspeed.  

  10. How does the lift depend on altitude?

     Lift decreases with altitude.

  11. How does the lift depend on wing angle?

     Lift increases with wing angle until a certain maximum angle is reached and stalling occurs.

     

  12. How does the lift depend on wing thickness?

     Lift increases with wing thickness.

  13. How does the lift depend on wing camber?

    Lift increases with wing chamber
