Calculation of Subsonic Flutter Derivatives for Arrowhead Wing with Control Surfaces

  • Doris E. Lehrian
  • Published 1967


An oscillatory lifting-surface theory for subsonic flow (Ref. 1) is used to calculate the aerodynamic forces on an oscillating arrowhead wing of aspect ratio 2 with trailing-edge control surfaces of varying span. The collocation method is outlined for simple harmonic motion of arbitrary mode and frequency and is applied for modes of plunging, pitching and… (More)
