摘要： A method (100) for detecting a burner failure in a gas turbine engine (10) that has a combustor (16) and a turbine (40) disposed downstream of the combustor (16). The combustor (16) has a plurality of burners (50) arranged annularly. The method (100) includes providing a plurality of temperature sensors (60) arranged annularly at an outlet (45) of the turbine (40); obtaining a plurality of temperature signals (62) from the plurality of temperature sensors (60); determining a plurality of validated temperature signals (64) from the plurality of temperature signals (62); determining a temperature focus (65) at least based on the plurality of validated temperature signals (64); improving the temperature focus (65) such that the temperature focus (65) is within a tolerance range (66); and performing at least one hazard protection action (90) at least when the temperature focus (65) crosses a predetermined threshold (68).

摘要： A fuel injector (18) for a hydrogen combusting aircraft gas turbine engine has at least one air through-passage (44, 52) extending axially from a front face (40) to a rear face (54). The injector further comprises a fuel manifold (42) in communication with a hydrogen fuel feed line (38). A plurality of fuel outlets (64) is provided surrounding the or each air passage (44, 52) and an annular fuel gallery (76) is provided around each air through passage (44, 52) configured to supply the fuel outlets (64), the annular fuel gallery (76) communicating with the fuel manifold (42).

摘要： Described herein is a non-contact excitation system for a spin rig comprising: a plurality of test piece elements for attachment to a test piece for rotation about an axis of rotation of the spin rig; and a plurality of exciter elements arranged around the axis of rotation, wherein the test piece elements and the exciter elements are magnetically attractive; wherein the test piece elements and/or the exciter elements comprise magnets; and wherein, in use, the exciter elements are arranged around the test piece; wherein each exciter element is axially and radially offset from the plurality of test piece elements. Also described is a method of testing a test piece using the system.
