Patent number: 11428123Abstract: An engine pod for a gas turbine engine which includes a pod wall having an inside and an outside. The pod wall includes a fixed downstream portion and a displaceable upstream portion which is displaceable in the axial direction between a first upstream position and a second downstream position. At its downstream end facing the fixed portion, the upstream portion forms a radially outer rear edge and axially spaced therefrom a radially inner rear edge, with a recess in between. It is provided that adjacent to the recess, an air-permeable structure is formed in the upstream portion which is intended and configured, in the first upstream position of the displaceable portion, to conduct air flowing in the region of the recess to the inside of the displaceable portion. According to a further aspect of the invention, the axial position of the radially inner rear edge varies in the circumferential direction.Type: GrantFiled: April 20, 2021Date of Patent: August 30, 2022Assignee: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventors: Marco Rose, Gregory Mack, Christoph Richter, Fredi Holste, Carlos Omar Marquez Gutierrez, Jürgen Dierke

Publication number: 20180094582Abstract: A turbofan engine for a civil supersonic aircraft, including: a multi-stage fan, wherein each stage of the multi-stage fan has a fan rotor with rotor blades and a fan stator with stator blades; an inlet flow channel that leads through the fan rotor of the first stage of the multi-stage fan; a primary flow channel that leads through a core engine of the turbofan engine; and a secondary flow channel that leads past the core engine. The inlet flow channel divides into the primary flow channel and the secondary flow channel. It is provided that the fan rotors of all stages of the fan are arranged in the inlet flow channel before it is divided into the primary flow channel and the secondary flow channel.Type: ApplicationFiled: September 29, 2017Publication date: April 5, 2018Inventors: Knut ROSENAU, James Robert MCLEAVY HILL, Marco ROSE

Patent number: 9605621Abstract: The present invention relates to a nozzle with a nozzle surface area and a nozzle rim, on which first and second guiding devices are alternatingly provided in the circumferential direction, where the first guiding devices are of the nozzle-type design and the second guiding devices are of the diffuser-type design. The first guiding devices each have a first azimuthal guide wall and two wall elements, with the first azimuthal guide wall forming a first trailing edge and two first edges to the wall elements. The second guiding devices each have a second azimuthal guide wall and two wall elements, with the second azimuthal guide wail forming a second trailing edge and two second edges to the wall elements. A wall element connects a first guiding device and a second guiding device. The wall elements have a curved course in the axial direction.Type: GrantFiled: November 5, 2013Date of Patent: March 28, 2017Assignee: Rolls-Royce Deutschland Ltd & Co KGInventors: Marco Rose, Rene Spieweg

Patent number: 7516815Abstract: A device for simulating sound produced by certain equipment, for example a rotor-stator arrangement of a turbomachine, or for generation of opposing sound fields for active sound control, including active sound reduction and active sound amplification, comprises flow obstacles (2) provided in a flow duct (1) flown by a fluid at which vortices (5, 6) are shed at a certain frequency depending on the shape and size of the flow obstacles and the velocity of flow. The quantity and spatial arrangement of the flow obstacles is selected such that a periodically spatially and temporally changing pressure field for the excitation of a sound field (8) of a certain modal content is produced by the entirety of the vortices shed. This sound field reacts synchronizingly on the vortex shedding. The resonant circuit so formed, whose vortex shedding frequency is in the range of the resonant frequency of the sound field to be excited, is the sound source.Type: GrantFiled: March 2, 2005Date of Patent: April 14, 2009Assignee: Roll-Royce Deutschland Ltd & Co KGInventors: Marco Rose, Fredi Holste, Frank Arnold, Alastair D Moore
