Abstract

A flutter exciter includes first and second impellers rotatably connected together by coupling means and rotatable about a common axis in opposite directions, each impeller having at least one vane so that fluid flowing over the vanes causes the impellers to rotate and each to generate a rotating force, the resultant of the rotating forces being an oscillating substantially rectilinear excitation force.
