Abstract
A turbine wheel on a horizontal shaft is coaxially mounted within a primary nozzle, for support in a river current below a platform carrying electrical power generation equipment. The turbine shaft and primary nozzle are submerged and oriented to enable flow of a portion of river current through the nozzle and past the turbine wheel. The external surface of the nozzle is shaped and has structure to accelerate and/or direct the flow of the adjacent surrounding maintstream river current in a manner to generate a sheath which aids the efflux of that portion of the river current which has passed through the turbine. Part of the said structure is a secondary nozzle surrounding the primary nozzle; the secondary nozzle is arranged to accentuate the control of the surrounding mainstream river current. Bearing means, support means, power take-off means, speed control means and blade shapes are disclosed.
