Wing Area Effects

Answers

Aeronautics Logo

  1. Go to the Foilsim Software Program and set initial conditions as follows:
    Airspeed = 100 km/h, Altitude = 5000 m, Angle = 1 deg , Thickness = 12.5, Camber = 12.5, Area = 10 sq. m.

    What is the Lift? 4757 Newtons

     

  2. Change the area as shown in the following table and record the associated lift for each area to complete the table.
    Wing Area(sq. m)
    Lift(Newtons)
    10
    4,757
    20
    9,513
    30
    14,270
    40
    19,030
    50
    23,780
    60
    28,540
    80
    38,050
    TABLE 1 
  3. Construct a graph of Wing Area's effect on Lift with an Independent Variable (X) of Wing Area and a Dependent Variable (Y) of Lift. Label each axis correctly to include units. Print out graph from FoilSim Program.

     

  4. Interpolate the lift for a wing area of 70 sq. m. What is the lift? 33,299 Newtons

     

  5. Extrapolate the lift for a wing area of 100 sq. m. What is the lift? 47,575 Newtons

     

  6. What is the shape of the curve formed by this relationship? A line

     

  7. Write the equation for this relationship! Y = 475.75 X where Y = lift and X = area

     

  8. Based on the relationship between lift and area of a wing, how would you increase the lift on a wing? Increase the Area of the Wing!!!
