| 摘要 |
The invention concerns a squirrel-cage type turbine whereof the bars are linked to profiled blades (2), each of which being arranged, when the turbine is not operating above the water surface, such that it remains perpendicular to the radius (R) with which it is associated. Said turbine is immersed in a water current perpendicular to its shaft (3), by being mounted either on a floating craft (7) or on a heavy base (8) anchored on the floor of the water expanse. Its omnidirectional character enables it to operate in so-called rotary tidal currents. Said turbine, even if there is a large number of them beneath the water surface, can be entirely invisible and not obstruct navigation, thereby preserving the integrity of natural sites. The blades, or their linkage with their associated bar, are flexible and elastic so as to be better adapted to the angles of attack of the relative flow on each blade, for energy gain and very easy starting.
