WING CHARACTERISTICS. 



Example. We will take an overall span of 36 feet, of which 

 2 feet 6 inches is rounded off in plan at each tip : gap, 5 feet ; 

 chord, 6 feet ; stagger, 3 ; R.A.F. I 5 section. We will take the 

 model test data for this wing given on page 87. 

 Then aspect ratio = \ = 6 ; 



gap/chord = J = '834 ; 

 stagger = 3; 



wing tip rounding = _ > = -417 of chord; 



dimensions = 120. 



We can now fill up, with the aid of pages 88 to 97 the 

 following table : 



The figures in the last column are now in the form required 

 for use in machine performance calculations.
