Abstract

A system for converting between fluid movement, such as wind, and mechanical rotation is disclosed. The system includes a support which is rotatable about a first axis orthogonal to the direction of fluid movement and at least one panel mounted on the support for rotation about a said axis. The panel includes a matrix of flaps (elementary panels) mounted on the panel framework for rotation about a multiple secondary axes; and retaining hardware serving to resist rotation of the said flaps during a first portion of the rotation cycle of the support and permitting the flaps to rotate freely during a second portion of said cycle. The panel provides a driving torque during said first portion of the cycle and moving freely to an orientation of minimum fluid resistance during said second portion.
