Patent number: 11879350Abstract: A gas passage for a gas turbine engine, which allows for quicker and easier determination of the condition of a liner within the gas passage without the need for dismantling the entire gas passage, or irreparably damaging large sections of the liner. The gas passage comprises a casing with one or more plugs which are at least partly coated in a material matching the material composition of the lining, which can be removed from the gas passage in order to analyse the condition of the lining material.Type: GrantFiled: October 7, 2022Date of Patent: January 23, 2024Assignee: Rolls-Royce plcInventors: Glen Pattinson, Daniel P. Everington

Publication number: 20230374667Abstract: A method for improving the corrosion and fatigue crack resistance of an article that has a surface. The method involves: providing a dry powder having one or more anti-corrosion materials; pressurising the dry powder to 1 to 5 MPa in an inert gas; pre-heating the surface of the article to a temperature of 50 to 900° C. and cold-spraying the surface of the article with the dry powder at a particle velocity of 300 to 1200 m/s so that a corrosion and crack-resistant coating is formed on the surface of the article and the surface is modified to an average depth of 10 to 100 ?m.Type: ApplicationFiled: April 24, 2023Publication date: November 23, 2023Applicant: ROLLS-ROYCE PLCInventors: Glen PATTINSON, Matthew C APPLETON

Patent number: 8876466Abstract: A seal is provided between first and second relatively movable members. The seal comprises a liner attached to the first relatively movable member which liner is abraded by the second relatively movable member. The abradable liner comprises a metallic, open porous structure formed by fusing a metallic feedstock with an energy beam to build up sequential deposits of the fused feedstock.Type: GrantFiled: March 12, 2012Date of Patent: November 4, 2014Assignee: Rolls-Royce PLCInventors: Glen Pattinson, Andrew Hewitt

Patent number: 8650753Abstract: A seal (48) between a compressor rotor blade (26) and compressor casing (28) comprises an abradable structure (59) on the compressor casing (28). The abradable structure (59) comprises a metallic foam (60) having pores (66, 68). The metallic foam (60) has a first a region (62) and a second region (64). The first region (62) of the metallic foam (60) is arranged adjacent to the compressor casing (28) and the second region (64) of the metallic foam (60) is spaced from the compressor casing (28) by the first region (62) of the metallic foam (60). The pores (68) of the second region (64) of the metallic foam (60) contain an abradable material (70) and the pores (66) of the first region (62) of the metallic foam (60) do not contain an abradable material.Type: GrantFiled: October 8, 2009Date of Patent: February 18, 2014Assignee: Rolls-Royce, PLCInventors: Christopher Sellars, Glen Pattinson, John T Gent

Publication number: 20130004261Abstract: A first element (10) adapted to selectively engage a second element (20), wherein the first element comprises a coating (12) and at least an engaging portion (14) of the first element is coated in said coating, wherein the coating is formed by vapour deposition to provide a thermo-chemically stable layer for temperatures up to 800° C. The coating (12) may comprise one or more of a nitride, oxide or carbide of titanium, chromium or aluminium.Type: ApplicationFiled: June 20, 2012Publication date: January 3, 2013Applicant: ROLLS-ROYCE PLCInventors: Glen PATTINSON, Michael ROBINSON
