  for a given aspect ratio. This is illustrated 
  by the lift curve comparison of figure 3.15 
  Any 
  for 
  reduction of lift curve slope implies the 
  wing is less sensitive to changes in angle of 
  attack. This is a beneficial effect only when 
  the effect of gusts and turbulence is con- 
  sidered. Since the swept wing has the 
  lower lift curve slope it will be less sensitive 
  due 
  to gusts and experience less “bump” 
  to gust for a given aspect ratio and wing 
  loading. This is a consideration particular 
  to the aircraft whose structural design shows 
  the gust load 
  a predominating effect of 
  spectrum, e.g., transport, cargo, and patrol 
  types.

  (2) “Divergence” of a surface is an aero- 
  elastic problem which can occur at high 
  dynamic pressures. Combined bending and 
  twisting deflections interact with aerody- 
  namic forces to produce sudden failure of 
  the surface at high speeds. Sweep forward 
  will aggravate this situation by “leading” 
  the wing into the windstream and tends to 
  lower the divergence speed. On the other 
  hand, sweepback tends to stabilize 
  the 
  surface by “trailing” 
  and tends to raise the 
  divergence speed. By this tendency, sweep- 
  back may be beneficial in preventing di- 
  the anticipated speed range.
