Patent number: 9670786Abstract: A rotary blade tip insert for incorporation into a rotary blade, for example, a rotary fan blade in a gas turbine engine. The tip insert comprises a sleeve for insertion into a recess provided in said rotary blade. The sleeve has a radially outer end defining an opening, a radially inner end and opposing wall portions extending between said ends. The tip insert further comprises a tip element having a crown portion and a root portion for insertion into the opening of said sleeve.Type: GrantFiled: June 2, 2015Date of Patent: June 6, 2017Assignee: ROLLS-ROYCE plcInventors: Simon Read, Matthew D Curren

Patent number: 9102396Abstract: A mechanical joint for joining two components, the joint having a male part on one component and a corresponding female part on the other component. The male and female parts have respective castellations which intercalate on insertion of the male part into the female part along a direction of insertion. Respective abutment surfaces are formed on the projections of the castellations. The castellations are configured such that, after the insertion of the male part into the female part, the male and female parts can be rotated relative to each other around the direction of insertion to bring: (i) the abutment surfaces into facing alignment and thereby prevent the parts from being pulled apart, and (ii) the indentations of the castellations into facing alignment. The joint has one or more locking members which are insertable into the facing indentations to prevent further relative rotation of the male and female parts.Type: GrantFiled: July 2, 2010Date of Patent: August 11, 2015Assignee: ROLLS-ROYCE PLCInventor: Matthew D Curren

Patent number: 9074478Abstract: A damped assembly within a gas turbine, comprising a first member and a second member mechanically connected via an intermediate vibration dampener which has at least first and second surfaces for contacting the first and second members respectively, wherein either or both of the first and second surfaces include a plurality of raised portions in direct contact with the respective member and a plurality of recessed portions which contain adhesive for bonding the intermediate vibration dampener to the respective member.Type: GrantFiled: August 11, 2011Date of Patent: July 7, 2015Assignee: ROLLS-ROYCE plcInventors: Eric P. Ravey, Matthew D. Curren

Publication number: 20120321443Abstract: A tip treatment bar and associated rotor casing structure, wherein the tip treatment bar includes a solid composite structure having a plurality of layers arranged therein so as to provide the bar with a directional stiffness characteristic. Such a layered composite arrangement can be used to tailor the vibration characteristics of the bar. The tip treatment bar and casing structure may be suited for mounting relative to a fan or compressor in a gas turbine engine.Type: ApplicationFiled: June 8, 2012Publication date: December 20, 2012Applicant: ROLLS-ROYCE PLCInventors: Eric P. RAVEY, Fabienne M. RAVEY, Matthew D. CURREN
