Abstract
A generator assembly for generating power in the downhole end of a drill string used to form a borehole in horizontal directional drilling. The drill string provides a fluid passageway in which the downhole generator is receivingly disposed, at least in part, to subject a rotatable turbine to a pressurized fluid flowing in the fluid passageway, thereby imparting a mechanical rotation to the turbine. The turbine is coupled to a generator so that the mechanical rotation of the turbine is transferred to a power output of the generator.
