Abstract: A method for fabricating a combustor liner for a gas turbine engine is provided. The method includes providing an annular shell including a plurality of circumferentially extending panels, wherein the plurality of circumferentially extending panels includes a first panel positioned at an upstream end of the shell and a second panel positioned downstream from, and adjacent to, the first panel. The method also includes forming a plurality of primary dilution holes in the first panel and forming a plurality of secondary dilution holes in the second panel, wherein the primary and secondary dilution holes are configured to discharge dilution air into the shell.

Abstract: A behind-the-ear assistive listening receiver having a housing containing an RF receiver. The housing includes a cavity in which two or more crystal carriers are removably insertable. Each of the crystal carriers contains an oscillation crystal tuned to a particular frequency corresponding to an RF frequency desired to be received by the user. A switch is provided for permitting the user to select one of the oscillation crystals to automatically tune for the RF receiver to the desired RF frequency. Each crystal carrier may contain visible indicia indicating the frequency to which it is tuned, and the carriers may be positioned in the housing so that the indicia are generally visible to others when the receiver is worn by the user. The assistive listening receiver may also include a conventional hearing aid microphone for converting ambient sounds into an electrical hearing aid signal. A mixer is provided within the housing for mixing the hearing aid signal with the RF signal to provide a mixed output signal.
