Helical Turbine Rotor

The Problem

The rapidly growing worldwide demand for renewable energy provides an unparalleled opportunity for development of new high performance technologies with efficiency and cost being the main driving factors. Tidal & Hydropower feature highly in this mix where methods are applied to convert the potential and kinetic energy stored in a fluid flow into useable electric power. This high profile project was initialised to capitalise on this growing demand through the development of a new type of Helical Turbine Rotor suitable for this energy conversion.

The Approach

The development of a new type of energy conversion device required technological innovation to increase the efficiency and performance of existing machines of this nature. In particular, the use of a ‘conic helix’ type of rotor design was investigated whereby the geometry of the rotor blades were constructed from a mathematical equation of a conic helix.

The Result

The development of this device has progressed rapidly from feasibility stage to concept development whereby an initial prototype tidal power device has already been created and tested. In addition, international and national patent applications have been filed and the project has attracted significant attention from government funding and international investors.
