Abstract
A swirler includes an inner body defining a swirl axis. A plurality of swirl vanes extend outward from the inner body. The swirl vanes define respective swirl slots therebetween for imparting swirl on a fluid passing through the swirl slots. A method of making swirlers includes additively manufacturing a stack of swirlers.
Claims10
A method of making swirlers comprising:
- additively manufacturing a stack of swirlers wherein each swirler includes:
- an inner body defining a swirl axis;
- and a plurality of swirl vanes extending outward from the inner body, wherein the swirl vanes define respective swirl slots therebetween for imparting swirl on a fluid passing through the swirl slots;
- wherein additively manufacturing the stack includes building an external ring and an inner point inside the external ring and additively manufacturing the vertical stack in a vertical build direction from the external ring and inner point;
- wherein the inner body of a lower most swirler in the stack originates from the inner point;
- additively manufacturing a support rod aligned with the swirl axis of the swirlers, wherein the support rod is between adjacent swirlers in the stack so that the inner bodies of swirlers in the stack can be built up, each starting from the central support rod and diverging therefrom in the vertical build direction;
- and
- separating the swirlers from one another by machining away the central support rod.

- wherein an external tube outboard of the swirl vanes is built up from the external ring to support the stack from outside;
- and
- machining the external tube away to separate the swirlers from one another.
