    摘要: A method of minimizing nitrous oxide emissions in a gas turbine engine includes a step of monitoring pressure fluctuations within a gas turbine engine combustor and a step of adjusting fuel flow to the combustor if the pressure fluctuations therein exceed a preestablished threshold. The combustor can be operated at the lowest levels of nitrous oxide emissions since the onset of a combustor instability and/or blowout is identified early to allow for corrective action so that such undesirable events are prevented.

    摘要: A heat shield includes a panel having a forward face and an aft face, a circumferential outer side and a circumferential inner side such that the panel subtends a predetermined arc, and a first radially extending side and a second radially extending side each extending from the circumferential outer side to the circumferential inner side. The panel defines an opening extending between the forward face and the aft face, a lip projecting from the forward face and extending around the opening, a rail projecting from the forward face and extending around the lip to define a cavity region between the lip and the rail, and a plurality of holes in the cavity region. Each of the plurality of holes extends from the forward face to the aft face. A region of the panel extending from the lip to the circumferential outer side is free of any aft-projecting features.

    摘要: A cooling system for a turbine exhaust assembly comprises an annular case, a flowpath ring and a splash plate. The flowpath ring is coaxially disposed within the annular case. The splash plate extends axially between the annular case and the flowpath ring. A plurality of cooling fluid apertures is formed in the annular case, in order to provide cooling fluid flow onto the splash plate. A plurality of impingement holes is formed in the splash plate, in order to provide impingement flow onto the flowpath ring.
