Improvements in or relating to energy generation

Resumen de: GB2637454A

A turbine rotor has two blades 7, 8 connected to each other at a rotor hub with a connection which allows independent turning of each of the first and second blades about a pitch axis. The rotor blades’ centre of effort of thrust may be offset from the pitch axis to induce a ‘nose-down’ pitching moment of the blades. The connection between the blades may be resilient 22 so that blades individually pitch ‘nose-down’ to alleviate excessive thrust loads. Because the blades pitch individually, they can respond to the load acting on each blade and so adapt to non-uniform flow. The blades may also passively flip so that they can be used in bi-directional e.g. tidal currents.
