Abstract

A method classifies a component feature of a component, the component including a blisk or a part of a blisk for a turbomachine, which has been manufactured using a production process. The method includes classifying the component feature as a function of a first feature specification and a second feature specification for a measured variable of the component feature. A second tolerance range of the second feature specification is extended as compared to a first tolerance range of the first feature specification. A second region of applicability of the component for the second feature specification is smaller than a first region of applicability of the component for the first feature specification. The production process reproducibly and/or systematically causes a larger mean deviation of the measured variable in the second region of applicability than in the first region of applicability.

A module for a turbomachine, including a guide blade arrangement, a seal carrier that is situated radially within an inner platform of the guide blade arrangement, seal carrier walls, namely, a first seal carrier wall and a second seal carrier wall, and a sliding body as well as a connecting element. The seal carrier walls have a multipart design with respect to one another, and the second seal carrier wall is fastened to the first seal carrier wall and to the seal carrier via the connecting element. The sliding body holds the seal carrier walls at a distance from one another in such a way that they mutually axially delimit a clearance in which the guide blade arrangement engages via a radially inwardly extending guide pin. A radially inner section of the second seal carrier wall has frictional contact relative to the seal carrier.

Abstract

The invention is directed to a method for cleaning powder residues of an additive layer build-up method away from an at least partly additively manufactured component by a cleaning device, wherein a machine plate and the component arranged thereon are excited to mechanical oscillation during a cleaning process by a vibration actuator of the cleaning device with a set resonant frequency of the machine plate. According to the invention, before the cleaning process is carried out, a resonant frequency of the machine plate is set to the set resonant frequency by an arrangement of a mass element on a securing element of the machine plate.

Abstract

A method for automatically generating an optimized maintenance plan for a fleet of aircraft engines, includes the steps of: acquiring input data on a plurality of engines and providing an existing initial maintenance plan or creating an initial maintenance plan based on the acquired input data. A total maintenance effort for the fleet resulting in an application of the initial maintenance plan is then determined. Next, the engines are sorted into a defined order according to at least one criterion and at least one optimization strategy or heuristic stored as an algorithm in a computer program is applied to each of the engines in the defined order. Next, an optimized maintenance plan for the engines or output data comprising an estimated total maintenance effort of the optimized maintenance plan is output.
