Patent number: 10809203Abstract: There is described an inspection device for inspecting a slot of a gas turbine engine. The inspection device comprises: an insert for insertion into the slot; a plurality of imaging devices coupled to the insert; and a processor. The insert is movable along a longitudinal axis of the slot. Each of the plurality of imaging devices is positioned adjacent an external surface of the insert and is configured to capture an image of a portion of the slot adjacent the imaging device. The processor is configured to receive data corresponding to the images captured by the plurality of imaging devices. There is also described a method of inspecting a slot using the inspection device.Type: GrantFiled: January 29, 2019Date of Patent: October 20, 2020Assignee: ROLLS-ROYCE plcInventors: Wei Keong Ten, Murukeshan Vadakke Matham, Iulian Marinescu, Nicholas Weeks, Wei Yi Yeoh, Aswin Haridas

Patent number: 10155236Abstract: A Cold spray nozzle assembly for depositing powder material onto a component surface includes a primary spray nozzle, two or more secondary spray nozzles, and a support mechanism supporting each spray nozzle. Each spray nozzle deposits powder material on a single target point on the surface, a reference plane being defined normal to a surface plane at the target point. The primary nozzle is in a primary plane that is normal to the surface plane, and that defines a primary dihedral angle with the reference plane. An axis of the primary nozzle defines a primary nozzle angle with the surface plane. Each of the secondary spray nozzles is in a corresponding secondary plane, with each being normal to the surface plane and defining a respective secondary dihedral-angle with the reference plane. An axis of each secondary spray nozzle defines a respective secondary nozzle angle with the surface plane.Type: GrantFiled: December 15, 2016Date of Patent: December 18, 2018Assignee: ROLLS-ROYCE plcInventors: Adrian W Y Tan, Erjia Liu, Iulian Marinescu
