Abstract:
1. A gas turbine entrainment system for mixing combustion gases and non-combustion gases, the entrainment system comprising: an axial body having a first end and a second end; a plurality of helical vanes radially disposed with respect to the axial body, each of the helical vanes having a root attached to the axial body and a tip opposite the root; and a plurality of trenches formed by the helical vanes, each trench radially receiving combustion gases from the tip towards the root, each trench receiving non-combustion gases from the first end of the axial body to the second end of the axial body in a helical flow path to quench the combustion gases with the non-combustion gases.
