A seal ring system, comprising: a first plurality of segments (202; 402) forming a first row of segments (202; 402) having an annular shape, wherein each segment (202; 402) of the first row of segments (202; 402) defines a slot, a petal (214; 408) along the slot, and an opening (204; 404; 522) offset from the slot; a retention fastener disposed in the opening (204; 404; 522); wherein a gap (212; 412) being defined between each circumferentially adjacent segment (202; 402) of the first plurality of segments (202; 402); a second row of segments (216; 410) axially adjacent the first row of segments (202; 402) and circumferentially staggered with the first row of segments (202; 402), such that each segment (216; 410) of the second row of segments (216; 410) overlaps circumferentially adjacent segments (202; 402) of the first plurality of segments (202; 402) to prevent air flow through the gap (212: 412); the retention fastener being a retention pin (206; 406; 518) and the opening (204; 404) of said each segment of the first row of segments (202; 402) being larger than the retention pin (206; 406) in a radial direction, such that the first plurality of segments (202; 402) are allowed to move in a radial direction relative to the retention pin (206; 406); and the opening (204; 406) of said each segment of the first row of segments (202; 402) being a racetrack slot in the form of an elongated oval shaped opening, wherein each segment (216; 410) of the second row of segments (216; 410) has a second opening (204; 404; 522) offset from center, and the retention fastener is also disposed in the second opening (204; 404; 522). a first plurality of segments (202; 402) forming a first row of segments (202; 402) having an annular shape, wherein each segment (202; 402) of the first row of segments (202; 402) defines a slot, a petal (214; 408) along the slot, and an opening (204; 404; 522) offset from the slot; a retention fastener disposed in the opening (204; 404; 522); wherein a gap (212; 412) being defined between each circumferentially adjacent segment (202; 402) of the first plurality of segments (202; 402); a second row of segments (216; 410) axially adjacent the first row of segments (202; 402) and circumferentially staggered with the first row of segments (202; 402), such that each segment (216; 410) of the second row of segments (216; 410) overlaps circumferentially adjacent segments (202; 402) of the first plurality of segments (202; 402) to prevent air flow through the gap (212: 412); the retention fastener being a retention pin (206; 406; 518) and the opening (204; 404) of said each segment of the first row of segments (202; 402) being larger than the retention pin (206; 406) in a radial direction, such that the first plurality of segments (202; 402) are allowed to move in a radial direction relative to the retention pin (206; 406); and the opening (204; 406) of said each segment of the first row of segments (202; 402) being a racetrack slot in the form of an elongated oval shaped opening, wherein each segment (216; 410) of the second row of segments (216; 410) has a second opening (204; 404; 522) offset from center, and the retention fastener is also disposed in the second opening (204; 404; 522).
