Abstract
A scroll or torus has a variable thickness and variable radius structure rib support. The scroll or torus may be suitable in high temperature applications while avoiding the high stress found with conventional constant radii ribs and the weight penalty found in stainless steel scrolls and torus. The scroll or torus may be used, for example, on a turbo compressor machine in aircraft environmental control systems.
Claims10
A scroll or torus comprising:
- a plurality of ribs connecting the scroll or torus to a housing, wherein the ribs have a variable fillet radii.
A scroll or torus for a turbo compressor machine, the scroll or torus comprising a plurality of ribs connecting the scroll to a housing, wherein the ribs have a variable fillet radii and a variable thickness.
A method for controlling stress of a scroll or torus mounted on a housing, the method comprising:
- connecting the scroll or torus to the housing with a plurality of ribs;
- and
- forming the ribs with a variable fillet radii.
