A turbine exhaust drain system has a sump where liquid collects and a suction pipe having an inlet end fluidly connected to the sump and an outlet end fluidly connected to a core gas path of a turbine exhaust case. In use, the combustion gases flowing through the exhaust case creates a venturi effect to draw the liquid from the sump into the core gas path where the liquid and the combustions gases combine into a mixed flow before being discharged through an outlet end of the exhaust case.

An apparatus and method of reducing a flow of fluid and heat between a first space and a second space in a rotatable machine and an integral seal and heat shield device are provided. The device includes an annular flange configured to couple to the rotating member of the rotatable machine and a multi-walled seal shield member extending axially from the flange. The multi-walled seal shield member is formed integrally with the flange. The seal shield member includes a first wall including a plurality of surface features, a second wall spaced radially inwardly with respect to the first wall, and a cavity formed between the first and second walls. The integral seal and heat shield device also includes a cap end integrally formed and configured to seal the first and second walls. Each of the flange, the seal shield member, and the cap end are formed of a sintered metal.

This steam turbine is provided with a rotor shaft which rotates about an axis, a plurality of rows of moving blades which are fixed to the outside, in the radial direction, of the rotor shaft, and which are disposed spaced apart in the axial direction along the axis, a casing disposed in such a way as to cover the rotor shaft and the plurality of rows of moving blades, and rows of stationary blades which are fixed to the inside, in the radial direction, of the casing, are disposed spaced apart in the axial direction, and which are disposed on a first side, in the axial direction, of each of the plurality of rows of moving blades, wherein the rows of stationary blades are provided with: a plurality of stationary blades which are disposed spaced apart in the circumferential direction, and each of which extends in the radial direction.

A thrust reverser of a nacelle of a turbojet engine of an aircraft extending about a longitudinal axis and including a fixed structure and at least one door which is rotatable between a closed position and an open position and including a downstream frame spaced axially from a downstream end edge of the door by an axial clearance parallel to the longitudinal axis. The thrust reverser includes a system for diverting fluids to the exterior including at least one projection fixed onto the door or the other fixed structure and extending into the axial clearance and towards one of the fixed structure or the door, while leaving an axial gap between a free end of said projection and one of the fixed structure or the door.

An oil accumulator assembly may comprise a scavenge tube including an aperture defined by a break in the scavenge tube and/or an annular cylindrical structure concentrically situated about the scavenge tube. The aperture may be configured to receive oil flowing through the scavenge tube, and the annular cylindrical structure may be configured to accumulate oil flowing through the aperture. The oil accumulator assembly may further comprise a drainage outlet disposed in the annular cylindrical structure. Oil accumulated within the annular cylindrical structure may drain through the drainage outlet in response to an engine being shut down. The oil accumulated within the annular cylindrical structure may fill a portion of the scavenge tube situated within an engine fan case to prevent coking within the scavenge tube.
