WING CHARACTERISTICS 



of k c and L/D for values of X from 'I to I'O as required for use 

 in our table. For convenience a few of the best wings for 

 various types of machine are given hereunder in the required 

 form.* 



Tests on 6 : i Aspect Ratio Monoplane Models with Square 

 Tips. 3 Inch Chord Tested at 40 Feet per Second. 



Examples. For numerical examples illustrating the methods 

 of this chapter, see Chapter XVI., page 152, and Chapter XXII., 

 page 187. 



Theory. For theoretical explanations see Chapter II., page 

 13- 



* It is to be noted that a wing which falls entirely inside one of the wings here 

 given when L/D is plotted on L is completely inferior to the outer wing. There 

 are many wings which on this test are inferior to the wings here given, hut probably 

 few which are better : hence the small number of examples given.
