Patent number: 8808847Abstract: A layered composite component is disclosed, the component including: a plurality of stacked layers defining a component thickness between opposed component surfaces and at least one reinforcing element extending from each of the opposed component surfaces the reinforcing elements extending at least partially through the component thickness. Another layered composite component is also disclosed, the component including: a plurality of stacked layers defining a plane and having a primary in-plane axis, wherein the at least one block array of reinforcing elements extends into the component along a reinforcing direction that is angled with respect to the plane of the stacked layers, and wherein the at least one block array is angled in the plane of the stacked layers with respect to the primary axis.Type: GrantFiled: June 18, 2012Date of Patent: August 19, 2014Assignee: Rolls-Royce PLCInventors: Matthew P. Jevons, Robert Backhouse

Patent number: 8573948Abstract: An airfoil has a hollow shell providing external airfoil surfaces, and a corrugated core within the shell. The core contacts inner surfaces of the shell to support the shell. The airfoil is formed by consolidating a hollow shell pre-form and a corrugated core pre-form. At least a part of the hollow shell has a leading edge shell portion and/or a trailing edge shell portion which, before consolidation of the pre-forms, is a unitary body having a shape which wraps around the respective edge.Type: GrantFiled: October 27, 2009Date of Patent: November 5, 2013Assignee: Rolls-Royce, plcInventor: Matthew P. Jevons

Patent number: 8556579Abstract: The present invention relates to a reinforcing tip cap for an aerofoil blade. The tip cap comprises a body for attaching to the tip of an aerofoil blade and a plurality of abrading elements fixed in the body for abrading a surface against which the tip cap rubs in use.Type: GrantFiled: May 12, 2010Date of Patent: October 15, 2013Assignee: Rolls-Royce PLCInventor: Matthew P. Jevons

Patent number: 8540487Abstract: The present invention relates to an actuatable seal (14) for an aerofoil blade tip, for providing a seal between the blade tip (12) and an adjacent surface (10) over which the blade tip passes in use. The seal comprises a flexible member that is arranged in use to be mounted on the tip of a rotating aerofoil blade and to flex towards the surface under the action of centrifugal force when the blade rotates. The seal further comprises an actuator means provided on the flexible member and operably arranged in use to deflect at least a portion of the flexible member away from the surface.Type: GrantFiled: June 17, 2010Date of Patent: September 24, 2013Assignee: Rolls-Royce PLCInventors: Kristofer J. Bottome, Matthew P. Jevons

Patent number: 8506257Abstract: The present invention relates to an aerofoil (20) comprising a leading edge portion (22) and a flexible thin-walled portion (26) that is rearwards of the leading edge portion, defining a cavity (28), and a shape-forming insert (30) for inserting into the cavity. The shape-forming insert at least partly defines the profile of the aerofoil such that changing the shape of the insert changes the profile of the aerofoil.Type: GrantFiled: June 7, 2010Date of Patent: August 13, 2013Assignee: Rolls-Royce PLCInventors: Kristofer J. Bottome, Matthew P. Jevons

Patent number: 8281666Abstract: The present invention relates to a Test apparatus (10) for testing the interaction between through-thickness compression and shear in a test piece (16). The apparatus comprises first and second chocks (12, 14) arranged in use to securely retain a test piece, and first and second races (18, 20) which can be controllably urged towards each other to transmit a known force to the first and second chocks. The first and second chocks and the test piece together form a substantially cylindrical body of a first diameter and. The first and second races define therebetween a substantially cylindrical space of a second diameter for accommodating the chocks, and wherein the second diameter is greater than the first diameter.Type: GrantFiled: June 24, 2010Date of Patent: October 9, 2012Assignee: Rolls-Royce PLCInventor: Matthew P. Jevons
