A rotary body for use in a turbo machine comprising:
- a hub having an outer edge and a plurality of slots formed in the outer edge, the slots having first and second spaced-apart opposing inner surfaces extending from the outer edge to a depth within the hub;
- and
- a plurality of blades secured to the outer edge of the hub, the slots and the blades being arranged such that at least two of the blades are positioned between each pair of adjacent ones of the slots.
A rotary body for use in a turbo machine comprising:
- a substantially circular disk having first and second opposing sides, an outer edge interconnecting the first and second sides, and a plurality of slots formed in the outer edge;
- and
- a plurality of blades secured to the outer edge of the disk, the slots and the blades being arranged such that at least two of the blades are positioned between each pair of adjacent ones of the slots and each slot is positioned between a pair of adjacent ones of the blades, each slot being a first distance from a first blade of the respective pair of adjacent blades and a second distance from a second blade of the respective pair of adjacent blades, the second distance being greater than the first distance.
A method for constructing a rotary body for use in a turbo machine comprising:
- providing a substantially circular disk having first and second opposing surfaces and an outer edge interconnecting the first and second opposing surfaces;
- securing a plurality of blades having first and second opposing, curved surfaces to the outer edge of the disk such that the blades are substantially evenly spaced-apart;
- and
- forming a plurality of slots in the outer edge of the disk such that that at least two of the blades are positioned between each pair of adjacent ones of the slots and each slot is positioned between a pair of adjacent ones of the blades, each slot being a first distance from a first blade of the respective pair of adjacent blades and a second distance from a second blade of the respective pair of adjacent blades, the second distance being greater than the first distance.
