Abstract
A lobe mixer ( ) used in jet engines, is provided with diameter expansion portions ( ) in which the diameters gradually increase in the downstream direction, in which adjacent diameter expansion portions have different diameters from each other, and which guide the core gasses that flow along the inner sides of the adjacent diameter expansion portions, peripherally outwards at different angles. Thus, the gasses are mixed without the thrust of the jet engine being reduced, and the noise of the jet is reduced.
