Sealing system for a rotary machine and method of assembling same

A rotor assembly for a rotary machine comprising:

• a row of rotary components spaced circumferentially about a rotor disk, each said rotary component comprising:
• a platform comprising a first side channel and an opposite second side channel;
• a shank extending radially inwardly from said platform;
• and
• a dovetail region extending radially inwardly from said shank;
• and
• a plurality of axial seals, each of said axial seals sized and shaped to be received in, and sealingly interface with, said first side channel of one of said rotary components and said second side channel of an adjacent one of said rotary components.

A method of assembling a rotor assembly, said method comprising:

• coupling a plurality of rotary components in a circumferentially extending row of rotary components, wherein each rotary component includes:
• a platform including a first side channel and an opposite second side channel;
• a shank extending radially inwardly from the platform;
• and
• a dovetail region extending radially inwardly from the shank;
• and
• receiving each of a plurality of axial seals within the first side channel of one of the rotary components and the second side channel of an adjacent one of the rotary components in the row, each of the axial seals sized and shaped to sealingly interface with the first and second side channels.
