  configuration properties will beas follows: 
  
  slowed gradually 
  through a series of very 
  weak oblique shock waves to a speed just 
  above sonic velocity. Then the subsequent 
  normal shock to subsonic could be quite weak. 
  Such a combination of the weakest possible 
  waves would result in the least waste of energy 
  and the highest pressure recovery. The ef- 
  ficiency of various types of diffusers is shown 
  in figure 3.20 and illustrates this principle. 
  
  (1) The wing will be of low aspect ratio, 
  have noticeable taper, and have sweepback 
  depending on the design speed range. The 
  wing sections will be of low thickness ratio 
  and require sharp leading edges. 
  
  (2) The fmelagc and naceller will be of 
  high fineness ratio (long and slender). The 
  supersonic pressure distribution may create 
  significant lift and drag and require con- 
  sideration of the stability contribution of 
  these surfaces. 
  
  An obvious complication of the supersonic 
  
  to 
  the wing-low 
  aspect ratio, tapered, swept 
  and of thin section with sharp leading edge. 
  The controls will be fully powered and ir- 
  reversible with all movable surfaces the 
  most likely configuration. 
  
  (3) The t&Z surfaces will be similar
