ALM ENABLED COMBUSTION LINER ASSEMBLY
Publication/Patent Number: US2020208840A1 Publication Date: 2020-07-02 Application Number: 16/234,016 Filing Date: 2018-12-27 Inventor: Sauer, Kevin   Debruhl christopher d   Assignee: Rolls-Royce Corporation   Rolls-Royce North American Technologies Inc.   IPC: F23R3/00 Abstract: Systems and methods are provided for a combustion liner assembly comprising at least a portion of a combustion liner of a combustor, the combustion liner defining a combustion chamber. A chute integral with at least the portion of the combustion liner is provided, the chute having an inlet, an outlet, and a body extending between the inlet and the outlet. The body of the chute extends towards a midline of the combustion chamber. The inlet is located in an outer surface of the combustion liner, and the outlet opens into the combustion chamber. A cooling channel is provided that extends from the outer surface of the combustion liner along the body of the chute.

COMBUSTOR DOME VIA ADDITIVE LAYER MANUFACTURING
Publication/Patent Number: US2020141579A1 Publication Date: 2020-05-07 Application Number: 16/180,529 Filing Date: 2018-11-05 Inventor: Sauer, Kevin   Dailey, Lewis   Mccormick, Keith   Smith, Duane   Debruhl christopher d   Assignee: Rolls-Royce Corporation   Rolls-Royce North American Technologies Inc.   IPC: F23R3/00 Abstract: A combustor dome may be formed by way of additive layer manufacturing. The combustor dome may further include a raised outer surface and a recessed outer surface on a hot side of the combustor dome. The recessed outer surfaces may be closer to the cold side than the raised outer surfaces. The combustor dome may include a shadow surface defined between the raised outer surface and recessed outer surface. The shadow surface may define a corresponding cooling outlet in fluid communication with an internal cooling channel defined inside of the combustor dome. The cooling outlet may release air from the internal cooling channel to the hot axial side of the combustor dome.

Check valve for propulsive engine combustion chamber
Publication/Patent Number: US9551299B2 Publication Date: 2017-01-24 Application Number: 14/202,397 Filing Date: 2014-03-10 Inventor: Loebig, James C.   Debruhl christopher d   Holdcraft, John D.   Assignee: Rolls-Royce Corporation   Rolls-Royce North American Technologies, Inc.   IPC: F02K7/02 Abstract: A combustion chamber includes an inner wall, an outer wall surrounding the inner wall, and a flow passage between the inner wall and outer wall that permits forward flow and restricts reverse flow. The inner wall has a plurality of effusion holes in fluid communication with the inside of the combustion chamber. The outer wall has a plurality of cooling side holes in fluid communication with a cooling source. The inner wall and the outer wall define a flow passage therebetween that fluidly connects one or more of the cooling side holes with one or more of the effusion holes. The flow passage has a geometric configuration to permit forward flow of gases through the flow passage from the cooling source to the inside of the combustion chamber and to restrict reverse flow of gases through the flow passage from the inside of the combustion chamber to the cooling source. The permitted flow rate is greater than the restricted flow rate.
