A drainage structure includes: a main body including an intake flow path; a compressor impeller disposed in the intake flow path; an accommodation chamber formed in the main body at a position upstream of the compressor impeller in a flow of an intake air; a movable member disposed in the accommodation chamber; and a connecting passage connected to the accommodation chamber.

A blade for an engine includes an airfoil body having a pressure side and a suction side, a base, and a rib located on the pressure side of the airfoil body. The rib includes a radially outer surface inclined radially outwardly with respect to the pressure side of the airfoil body and a scoop formed by the radially outer surface. The radially outer surface is inclined radially outward with respect to a normal axis to the pressure side of the airfoil body. The rib is angled at a positive angle with respect to the platform. An engine for and a method of directing ingestion material in an engine may employ the rib.

A cleaning system for cleaning gas paths in an engine core of a gas turbine engine is provided. The cleaning system includes a source of an engine cleaning liquid; an engine cleaning mist forming unit that vapourises the engine cleaning liquid to form an engine cleaning mist and delivers the engine cleaning mist into the engine core of the gas turbine engine; at least one delivery device configured to deliver the engine cleaning liquid to the engine cleaning mist forming unit; a pump configured to draw the engine cleaning mist through the engine core to clean the gas paths within the engine core; and a mist collecting arrangement including a condensing chamber. The mist collecting arrangement is configured to collect the engine cleaning mist that has passed through the engine core and condense the collected engine cleaning mist in the condensing chamber.

This turbine stator vane extends in the radial direction which intersects the flow direction of steam, and includes a pressure surface facing the upstream side in the flow direction, and a suction surface facing the downstream side in the flow direction. A plurality of grooves are formed in at least the pressure surface, the grooves extending outward in the radial direction toward the downstream side. At the periphery of the grooves in the pressure surface, formed is a hydrophilic uneven region having greater hydrophilic properties than the pressure surface. The downstream-side ends of the plurality of grooves are connected to slits for capturing a liquified component of the steam.
