A replacement vibration absorbing device for replacing a wear wrap on a flexbeam includes a sleeve having a plurality of layers of vibration absorbing material, wherein an edge of the sleeve is cut so that the sleeve may be installed around a generally central portion of a flexbeam.

Vibration absorbing device for flexbeams

A fiber-optic sensor system includes a structure having a fiber-optic cable operatively connected thereto. The system includes a network controller with an interrogator operatively connected to the fiber-optic cable to receive optical energy indicative of a characteristic of the structure therefrom and convert optical energy to electrical energy and electrical energy to optical energy for data communication. A sensor and/or a data source are operatively connected to the fiber-optic cable through the network controller to transmit data through the fiber-optic cable and receive data therefrom.

Systems and methods for integrated, multi-functional, fault tolerant sensing and communication

Embodiments are directed to receiving, by a computing device comprising a processor, an anticipated usage input, a load input and a strength input associated with a unit, calculating, by the computing device, a baseline reliability value based at least in part on the anticipated usage input, the load input and the strength input, receiving, by the computing device, usage data associated with use of the unit, generating, by the computing device, an updated reliability value based on at least some of the inputs used to calculate the baseline reliability value and the usage data, and determining, by the computing device, a lifetime for the unit based on the updated reliability value.

Reliability maintaining serial number credit process

A method of repairing a damaged portion of a rotor blade includes filling the damaged portion with a filler material. A pre-cured patch assembly is applied over the damaged portion, the patch assembly including one or more laminate packs positionable at at least one of an upper rotor blade surface and a lower rotor blade surface and one or more overwrap plies positionable over the upper rotor blade surface and the lower blade surface. A repair structure for a damaged portion of a rotor blade includes a volume of fill material disposed at the damaged portion.
