[57] ABSTRACT

Hydro-turbine driven electrical generating unit. contained ina water tight bulb housing and submerged in a water current.is comprised of a rigid frame supporting a rotating system.consisting of a combination of turbine runner. turbine shaft.turbine shaft seal. bearings. speed-increasing transmission.generator. and couplings. and a central terminal block for theconnection of power. measuring and control cables andtubes. The generating unit can be tested. adjusted and

maintained outside of the bulb housing and the generatingunit can be lifted and installed into or removed from the bulbhousing . The bulb housing contains small side wall openingscorresponding with the connection points between the gen-erating unit and the bulb housing.
