摘要:
A power generation system (10) includes a processor and memory (40) storing instructions that cause the processor to receive a first set of sensor (42) data indicative of one or more ambient conditions with respect to the power generation system (10), determine whether one of the one or more ambient conditions is above a respective threshold, and send a signal to a valve (58) to open when the one of the one or more ambient conditions is below the respective threshold, such that the valve (58) is configured to fluidly couple a first fluid exiting a compressor (20) to an inlet of the compressor (20).
摘要:
A turbomachine casing assembly comprises a first casing portion for at least partially encasing one or more rotating aerofoil structures of a turbomachine and a second casing portion; the first casing portion being movable with respect to the second casing portion. One or more resilient elements are arranged so as to resist movement of the first casing portion with respect to the second casing portion.

An annulus filler is provided for mounting to a rotor disc of a gas turbine engine and for bridging the gap between two adjacent blades attached to the rotor disc. The annulus filler has a body portion which defines an airflow surface for air being drawn through the engine. The annulus filler further has a front attachment formation which connects a forward end of the body portion to the rotor disc and which allows rotational movement of the body portion thereabout. The annulus filler further has a rear attachment formation which connects a rearward end of the body portion to the rotor disc. The rear attachment formation comprises a spring element which extends between the body portion and the rotor disc. The spring element expands under operational centrifugal loading such that the rearward end of the body portion moves radially outwardly with the body portion rotating about the front attachment formation.
摘要:
Ein erster Aspekt der Erfindung betrifft eine Schutzeimichtung (10) für eine Strömungsmaschine, insbesondere eine Gasturbine, mit einem Sicherungsring (12), welcher radial innenseitig an einem Gehäuseelement (14) der Strömungsmaschine angeordnet ist und welcher ein Durchdringen des Gehäuseelements (14) durch ein Teil eines Bauteils der Strömungsmaschine bei einem strukturellen Versagen dieses Bauteils wenigstens überwiegend verhindert, wobei der Sicherungsring (12) wenigstens in Umfangsrichtung aus einer Vielzahl von Ringsegmenten (16) besteht, welche formschlüssig miteinander verbunden sind. Ein zweiter Aspekt der Erfindung betrifft ein Flugtriebwerk.
