A gas turbine engine (20) comprises a fan rotor (85), a lower speed compressor rotor (90) and a higher speed compressor rotor (96), and a lower speed turbine rotor (94) and a higher speed turbine rotor (98). The lower speed turbine rotor (94) rotates the lower speed compressor rotor (96), and rotates a gear reduction (88) to, in turn, rotate the fan rotor (85). The higher speed turbine rotor (98) rotates the higher speed compressor rotor (96). An electrical generator (102) is driven to rotate with one of the lower speed turbine rotor (94) and the fan rotor (85).

An electrical power generation system consists of a ceramic hot face liner of a gas path enclosure thermally and mechanically connected to thermoelectric elements mounted on a conformal thermally conducting layer on the liner. Cooling channels connected to the backside of the thermoelectric elements provide a thermal gradient across the elements and resulting electrical power output. Clamps to maintain thermal and physical contact of all elements in the system are provided to maximize power generation.

An object of the invention is to provide a motor rotor structure for an electric turbo charger which can be manufactured at a low cost while ensuring the assembly quality of a motor rotor for an electric turbo charger by fixedly fitting, over a shaft, a rotor core having electromagnetic steel sheets pre-formed as an integrated stack in such a manner as to prevent the rotor core from rotating relative to the shaft. The motor rotor structure for an electric turbo charger is characterized by including: a rotor core (80) which is rotated by a magnetic field formed by a stator placed in a housing; a shaft (100) configured to rotate a compressor impeller (3) and the rotor core (80) together; and a bearing which supports the shaft (100) rotatably, wherein the motor rotor includes: the rotor core (80) which has electromagnetic steel sheets previously integrated as a stack; a stopper portion (28) which is formed at an intermediate portion of the shaft (100) in the thrust direction of the shaft to restrict axial movement of the rotor core (80); and a pressing unit (28, 43) which presses the rotor core (80) fitted over the shaft (100) against the stopper portion (28), the pressing unit preventing a circumferential phase shift between the shaft (100) and the rotor core (80) by a pressing force thereof, wherein the rotor core (80) has an inner sleeve (81) fitted over the shaft (100) and the plurality of electromagnetic steel sheets (67) which are fitted over the inner sleeve (81) and stacked on one another in a thrust direction of the inner sleeve (81), wherein the pressing unit (28, 43) presses the inner sleeve (81), and wherein the bearing arrangement (83 , 84) consists of ball bearings and the rotor core (80) has a side surface which is opposed to the ball bearings and which is formed with a flange portion (82) extending radially from an open end peripheral edge of the inner sleeve (81), wherein an elastic member (28) is interposed between the flange portion (82) and a bearing (83) of the ball bearing arrangement (83, 84).

Die Erfindung betrifft ein Verfahren zum Prüfen einer Überdrehzahlschutzeinrichtung einer eine Gasturbine (2), einen Generator (4) und eine Dampfturbine (3) aufweisenden Einwellenanlage (1), wobei das Verfahren die Schritte aufweist: a) Betreiben der Einwellenanlage (1) bei deren Nenndrehzahl und unter einer an den Generator (4) angeschlossenen elektrischen Last, wobei die Last derart gering gewählt wird, dass nach einem Abwurf der Last die Drehzahl der Einwellenanlage (1) derart ansteigt, dass die Drehzahl unterhalb einer Dampfturbinengrenzwertdrehzahl bleibt, die niedriger als eine Gasturbinengrenzwertdrehzahl ist, wobei die Überdrehzahlschutzeinrichtung derart eingerichtet ist, dass ein erster Überdrehzahlschutz ausgelöst wird, sobald die Drehzahl der Dampfturbine (3) die Dampfturbinengrenzwertdrehzahl erreicht, und ein zweiter Überdrehzahlschutz ausgelöst wird, sobald die Drehzahl der Gasturbine (2) die Gasturbinengrenzwertdrehzahl erreicht; b) Abwerfen der Last; c) Erhöhen des Massenstroms des in die Dampfturbine (3) eingeleiteten Dampfs und/oder des in die Gasturbine (2) eingeleiteten Brennstoffs derart, dass die Drehzahl der Dampfturbine (3) die Dampfturbinengrenzwertdrehzahl erreicht; d) Prüfen, ob der erste Überdrehzahlschutz ausgelöst wird.
