The coupling load measurement method allows to measure load between a first driving shaft and a second driven shaft connected by a hub coupled both with the first shaft and with the second shaft by at least one flexible coupling element coupled to the hub and to the first shaft and/or to the second shaft; the method comprises, during operation of the shafts, a measurement step of measuring a distance variation respect to a reference distance between a first flange of the hub and a second flange of the flexible coupling element and the step of using the measured distance variation for calculating the load.

A gas turbine fuel nozzle for a combustor of a gas turbine engine comprises a sleeve with an internal duct for premixed fuel gas flow; it further comprises a flame ionization sensor located on the sleeve externally to the duct; typically, the combustor has a single annular-shaped chamber.

A method to monitor a thrust load on a rolling bearing, obtaining a first parameter on the basis of at least a bearing cage rotation speed and of a first race rotation speed of a bearing, and subsequently obtaining a calculated thrust load on the basis of the first parameter and of the first race rotation speed.

Methods and systems providing for characterizing turbine blades, including characterizing the dynamics of one or more turbine blades or stages of a stage in terms of natural frequencies, normalized response intensity, and/or stage modal shape or nodal configuration. Such methods and systems comprise fluid (e.g., oil) excitation of bladed disks and quantitative modeling of the fluid excitation. Additionally or alternatively, such methods and systems may provide for analyzing modal shape or nodal configuration of a bladed disk (e.g., a turbine stage) based on a phase analysis of strain signals acquired from a bladed disk subjected to a fluid excitation, wherein the modal shape or nodal configuration corresponds to modes of blades coupled through a disc or shrouding.
