Abstract

The unsteady large amplitude linearized motion of a flexible slender wing in inviscid incompressible fluid is analysed. This extension to large amplitudes is made by assuming small local angles of incidence during motion along a finite amplitude trajectory. As a specific example, the periodic propulsion produced by a flexible slender wing is analysed for large amplitude harmonic motion with small local angles of attack and results for the available thrust and efficiency are presented.
