    Abstract: A combustor may include a combustor shell, a particle collection panel, and a combustor panel. The combustor shell may define a plurality of first impingement holes, the particle collection panel may include a plurality of particle collection chambers and may define a plurality of second impingement holes, and the combustor panel may define a plurality of effusion holes. The particle collection panel may be disposed inward of the combustor shell and the combustor panel may be disposed inward of the particle collection panel. Each particle collection chamber may have a closed inward end and an opening defined in an outward end. The particle collection chambers may be configured to entrap particulates.

    Abstract: A hydrostatic seal configured to be disposed between relatively rotatable components. The seal includes a base. The seal also includes a seal housing. The seal further includes a shoe operatively coupled to the base and extending axially from a forward end to an aft end. The seal yet further includes a plurality of teeth extending radially from a sealing surface of the shoe, one of the teeth being a longest tooth that extends furthest radially from the sealing surface, the axial distance from the forward end of the shoe to the longest tooth being greater than a radial distance from a radial tooth tip to the sealing surface.

    IPC: F02C7/18

    Abstract: A method of designing a gas turbine engine includes locating purge openings in fluid communication with a first stage cavity. At least one of a cover plate or a rotor disk is positioned adjacent the first stage cavity and radially inward from the purge openings. A portion of a rotor blade is positioned radially outward from the purge openings. A mass flow rate of cooling air through the purge openings is selected based on a radial location of the purge openings to create an air barrier between a radially inner side of the purge openings and a radially outer side of the purge openings.
