摘要： The invention relates to a 3-D measuring device (M) and to a method for three-dimensionally sensing elongate cut-outs, in particular grooves, in particular rotor grooves. The invention is characterized in that (S0; S1) positioning and fastening of an assembly on an elongate cut-out of a body, in particular a rotor, wherein a 3-D measuring head is connected to the assembly and is oriented toward the elongate cut-out for 3-D surface measurement, and (S2) three-dimensional scanning of the surface of the elongate cut-out by linearly guiding the 3-D measuring head along the longitudinal axis of the elongate cut-out are performed.

摘要： A method 200 and a system 10 are presented. The method 200 includes the steps of determining 208 normalized delta times of arrival corresponding to a plurality of blades 12 based upon actual times of arrival corresponding to the plurality of blades 12, and determining 220 static deflections of the plurality of blades 12 by removing effects of one or more common factors from the normalized delta times of arrival corresponding to the plurality of blades 12.

摘要： Radial turbomachine includes fixed case; one rotor disc installed in case and having rotor blades mounted on front face thereof; plurality of elements projecting from case and terminating proximity to rotor disc, wherein projecting elements include seal elements acting against rotor disc are operatively active on rear face of rotor disc or stator blades radially interposed between rotor blades of rotor disc; and one support plate bearing projecting elements and installed in case. Support plate is radially extended across from rotor disc and includes plurality of first circular portions concentric with rotation axis of rotor disc and plurality of second circular portions radially interposed between first circular portions. Several of first circular portions bear projecting elements and second circular portions are more deformable, along radial directions, than first circular portions in manner to allow relative movements between first circular portions when support plate is subjected to action of thermal gradients.

摘要： A method for predicting the remaining useful life of an engine (10) having components (18, 19, 22, 23) that are instrumented with sensors (50) that generate electronic data signals indicative of an operating condition of the component comprises identifying (52) one or more components and at least one failure mode for each component that limit an operating life of the components and engine (10). The method further comprises acquiring (62) and storing data relative to current operating conditions of the components associated with the identified failure mode; and, then determining (68) a remaining useful life of the component based on the data relative to current operating condition of the components, the data relative to historical data of the operating condition associated with the failure mode and a predicted failure mode rate.

摘要： A trip system for a steam turbine is provided which is capable of ensuring a sufficient flow rate when control oil is drained from a main stop valve. The present invention is provided with: an emergency shut-off device (10) for shutting off the supply of control oil; and a drainage device (45) for draining the control oil. The emergency shut-off device (10) is provided with: a chamber (22a) in which a piston (12A) is moved from a normal-operation position to an emergency position; a chamber (22b) through which the control oil is supplied to an ECV (32) during normal operation; a chamber (22c) through which the control oil for the ECV (32) is drained during an emergency; and a chamber (22d) through which the control oil for a TTV (31) is drained during an emergency. Piping through which the control oil is supplied includes: piping (L1) which is connected to chamber (22b); and piping (L2) which is connected in parallel to the drainage device (45), chamber (22a), chamber (22d), and the TTV (31), via an orifice (33).

摘要： Die Erfindung betrifft eine faseroptische Sensorvorrichtung (70), beispielsweise zum berührungslosen Messen von Abständen und Vorbeiflugzeiten, mit einer Sendeanordnung und einer Empfangsanordnung. Die Sendeanordnung umfasst einen ersten Sender zum Aussenden mindestens eines ersten Lichtsignals, wobei der erste Sender mindestens eine Sendefaser (72) aufweist. Die Empfangsanordnung umfasst mindestens N Empfänger, wobei jeder der N Empfänger mindestens eine Empfangsfaser (73, 74, 75, 76) aufweist, in einer anderen Entfernung zu dem ersten Sender angeordnet ist als die jeweils übrigen N-1 Empfänger und dazu eingerichtet ist, ein jeweils zugehöriges von N bei Reflexion des mindestens einen ersten Lichtsignals an einem Messobjekt entstehenden ersten reflektierten Lichtsignalen zu empfangen. Es ist vorgesehen, dass N mindestens 3 ist.
