Abstract: A method of manufacturing a hollow component, such as a fan blade for a gas turbine engine, includes the steps of: (a) providing first and second panels and a membrane; (b) providing a stop-off material on at least one of the first and second panels and the membrane to define regions where no diffusion bonding is to take place; (c) assembling the panels and the membrane together so the membrane is between the panels; (d) diffusion bonding the panels and the membrane together. The method is such that when assembled in step (c) the membrane does not extend to at least one edge of the first and second panels, so that in that region the first and second panels are diffusion bonded directly to each other.

Abstract: A torque estimator is disclosed for estimating torque on a machine. A computer system may include a torque estimator module located on the machine. The torque estimator module may be configured to receive a plurality of engine parameters, receive a drivetrain component parameter, determine an estimated torque value at the drivetrain component based on the plurality of engine parameters and the drivetrain component parameter. The computer system also may include an analysis module located on the machine. The analysis module may be configured to receive the estimated torque value and the drivetrain component parameter, and update a histogram data structure based on the estimated torque value and the drivetrain component parameter. The analysis module may also be configured to evaluate the histogram data structure in order to determine if excessive torque is being applied to a drivetrain component.

Abstract: Provision of component structures with line core elements are known but enhancing beyond a certain level of stiffness for impact resistance is difficult in view of manufacturing tolerances and bond region ratios. By providing discontinuous core elements 102, 32, 42 with through bonding creating gaps 39, 49 between them, bond regions 36, 46 are created. In such circumstances enhancement of local impact or load resistance through achieving specific desired support about the bond regions 46 can be achieved whilst remaining flexible (elastic) enough to resist cracking due to high cycle fatigue. In such circumstances within a structure 101, 41 both continuous core elements 40 and discontinuous core elements 42 can be provided and formed by simple plastic deformation in a single process whilst maintaining manufacturing tolerances and acceptability with regard to bond formation.

Abstract: Systems and methods are disclosed for automatically configuring an information management system of a work machine. A configuration method for an information management system includes requesting configuration data associated with one or more control modules. The method also includes receiving the configuration data associated with the one or more control modules in response to the request. The method further includes updating an information management system based on the received configuration data, wherein the update defines one or more operating parameters associated with the information management system.
