Vertical-axis wind turbine with removable sails on tubular armature to power boats or vehicles, uses tubular armature to carry vertical blades that open out to catch wind and fold back when returning against wind

摘要

The vertical-axis wind turbine has a tubular armature structure (1) with mobile blades (10) attached to the periphery. The blades open to catch the wind and close to reduce resistance when returning against the wind. The turbine drives an electric generator (4) through a reduction gear (5). The generator output can be used to supply an electric motor or to charge a battery.
