A fluid turbine designed for increased power output including an annular housing provided with a semispherical dome for directing incoming fluid flow from a fluid source in an angular and downward direction to impinge simultaneously on a plurality of radial, horizontal, rotor blades within the housing fixed to a vertical output shaft. The simultaneous impingement of the incoming fluid on all of the rotor blades quickly overcomes the initial inertia of the blades to rotation and maintains the rotor operating at peak velocity. The housing rotates independent of and coaxial to the rotor blades so as to position its fluid entrance passage normal to the direction of fluid flow and is provided with a plurality of fluid exit passages in its base so that deenergized fluid can be flushed from the housing by the downwardly directed flow which in conjunction with a low pressure area created behind a downwardly directed frontal scoop connected to the housing, which blocks the path of flow of the ambient fluid, causes additional fluid to be continuously drawn into the housing at high velocity to impinge on the rotor blades. The housing is gyroscopically stable and prevents the rotor from cutting back into the ambient fluid, which would retard rotation, while serving as a safety shield against flying debris entrained in the fluid stream.

A fluid turbine for generating power when disposed in a free flowing fluid, comprising a rotor means including a housing, and a plurality of rotor blades within said housing adapted to rotate in a reference plane about a longitudinal axis when exposed to said free flowing fluid, said housing being provided with a first fluid entrance passage therein for allowing fluid to enter said turbine in a direction lying within said reference plane to engage at least certain ones of said rotor blades, said housing being further provided with a second fluid entrance passage therein contiguous with said first fluid entrance passage for allowing fluid to enter said turbine in another direction oblique to said reference plane, means operatively connected to said rotor blades for generating power in response to rotation of said rotor blades, and means on said housing adjacent said first and second fluid entrance passages for directing fluid from said passages in a direction lying essentially within said reference plane to impinge upon said rotor blades, and in a direction oblique to said reference plane toward said blades to impinge upon all of said rotor blades, said means on said housing including side wall means spaced from said reference plane and inclined with respect to said longitudinal axis, said side wall means extending at least approximately two quandrants around the rotational path of said rotor blades to provide a space adjacent said rotor blades for producing spiral flow of fluid within said housing and between said wall means adjacent said rotor blades.
