Abstract
A hydraulic turbine having means for admitting air to the turbine draft tube. An annular air chamber about the draft tube has a plurality of circumferentially spaced openings into the interior of the draft tube. The pressure of the air in the air chamber is maintained below the maximum pressure of the water in the draft tube and above the minimum pressure of the water in the draft tube. This results in air entering the draft tube only at the areas of lowest water pressure and water entering the air chamber at areas of highest water pressure.
