Extract

This note attempts to clarify some basic ideas, and correct some common misunderstandings, on wing flexure-torsion flutter. Topics include:

  • (i) an understanding of the physics of wing flexure-torsion flutter through a number of specific examples,

  • (ii) an examination of the energy interpretation of the physics of flutter, indicating its limited usefulness,

  • (iii) a discussion of the significant differences between wing flexure-torsion flutter and the Duncan flutter engine,

  • (iv) a graphical representation to assess the contribution of various parameter to flutter onset,

  • (v) subcritical response below the critical flutter speed,

  • (vi) some practical wing flutter considerations.
