Provided is a corrosive environment monitoring device capable of monitoring the condition of a turbine for a long period of time without corrosion damage to a sensor caused by turbine steam. A corrosive environment monitoring device 10 includes: a steam extraction part 11 that extracts steam from inside of a casing 21 of a steam turbine 22 to outside thereof; a condensed water storage part 12 that stores therein condensed water produced by condensation of steam passing through the steam extraction part; and a corrosion factor sensor part 13 that detects properties of the condensed water. The condensed water storage part 12 includes a gap simulation part that simulates a gap inside the turbine and has a predetermined gap capable of storing the condensed water therein, and an annular channel formed on an outer periphery side of the gap simulation part. The corrosion factor sensor part 13 includes one or more sensors capable of measuring the properties of the condensed water, and a switching part configured to be capable of switching between contact and non-contact between the one or more sensors and the condensed water stored in the gap simulation part.

An apparatus and method for assembling an inducer assembly for inducing a rotation on an airflow passing within a turbine engine. The inducer assembly can provide a volume of fluid from a compressor section to a turbine section of the engine. The inducer assembly can include the combination of separate segments to form an annular inducer.

An aircraft engine has a combustor supplied by a hydrogen fuel system and is configured to combust hydrogen and generate water vapor. A water vapor collector receives at least part of the water vapor. A condenser is in fluid communication with the water vapor collector to receive and cool in the condenser the at least part of the water vapor and thereby condense at least part of the at least part of the flow of water vapor. A spray nozzle is in fluid communication with the condenser and operable to spray the condensed part of the at least part of the flow of water vapor onto a component of the aircraft engine.
