<p>PURPOSE: A pre-mixer, a manufacturing method thereof, and a turbo engine are provided to expand the mixture of gas with fuels to outside from a center rim in a radial direction. CONSTITUTION: A pre-mixer(110) comprises a mixing unit. The mixing unit comprises a rim, a central body(170), and a swirler(160). The rim is formed into the cylindrical shape. The central body is placed in the middle of the cylindrical shape in a flow direction. The swirler comprises vanes extended to the rim from the central body. The vanes determine the rotational motion of an inner flow when the flow of gas and fuel passes through the mixing unit.</p> |
