A ported shroud for a compressor associated with a gas turbine engine includes a primary inlet configured to be in fluid communication with the compressor, and the primary inlet is defined to extend along a central axis of the ported shroud. The ported shroud includes a bellmouth that surrounds the primary inlet, and a port plenum configured to be in fluid communication with the compressor. The port plenum extends along an axis that is transverse to the central axis of the ported shroud and transverse to a direction of fluid flow. The port plenum has a port plenum inlet defined about the axis, and the port plenum inlet is defined through the bellmouth such that a tortuous path is defined to the port plenum inlet. The port plenum including a port plenum outlet downstream from the port plenum inlet configured to be in fluid communication with the compressor.

The present invention relates to a stator of an axial compressor stage of a turbomachine featuring a radially outer blade ring forming an outer ring surface, a radially inner blade ring forming an inner ring surface, and several stator blades connected to the blade rings. It is provided that the outer ring surface and/or the inner ring surface has at least in a partial area a changing radius relative to a central axis of the stator both in the axial direction and in the circumferential direction.

A fan assembly for a gas turbine engine includes a fan including a plurality of fan blades. Each fan blade extends radially outwardly from a fan hub to a blade tip. The plurality of blade tips define a fan diameter. A nacelle surrounds the fan and defines a fan inlet upstream of the fan, relative to an airflow direction into the fan. The nacelle has a forwardmost edge defining an inlet length from the forwardmost edge to a leading edge of a fan blade of the plurality of fan blades. A ratio of inlet length to fan diameter is between 0.20 and 0.45. A nacelle inner surface defines a nacelle flowpath. The nacelle flowpath has a convex throat portion and a concave diffusion portion between the throat portion and the leading edge of the fan blade at a bottommost portion of the nacelle.

A blower assembly includes a housing including an inner shell and an outer shell that define a flow passage therebetween. The inner shell also at least partially defines a cavity. The blower assembly also includes a fan coupled within the housing such that the fan also at least partially defines the cavity. The blower assembly further includes a motor configured to rotate about an axis. The motor is coupled to the inner shell and is positioned within the cavity radially inward of the flow passage.

Provided are a blower, capable of suppressing noise occurring in a stator while significantly improving blowing efficiency, and an outdoor unit using the same. The present disclosure comprises: a bell mouth part spaced apart at a predetermined distance in the radial direction with respect to an outer circumferential end of a propeller fan; and a diffuser part installed on the downstream side of the bell mouth part, and having a flow path area which is enlarged from the upstream side toward the downstream side with a larger magnification rate than the magnification rate of the flow path area in the downstream end of the bell mouth part; and a stator part having a plurality of stators, wherein the stator part is arranged within the diffuser part.

A fan assembly includes an internal housing having an outer internal housing, and an inner internal housing partially disposed within the outer internal housing. The inner internal housing defines an internal cavity, and has a curved exterior surface. Stator blades extend between the inner internal housing and the outer internal housing.

A thrust generating apparatus for controlling an attitude of a movable body includes an outer shell body, a first inner shell body and a second inner shell body, a first fan rotating body and a second fan rotating body, an intermediate shell body, and a driving unit. A outer surface of the intermediate shell body has a shape such that an air flow sent from an opening end inside of any one of the first inner shell body and the second inner shell body is accommodated and flowed out to an outer flow path . When the first fan rotating body is rotated, the air flow suctioned from the outside in the axial direction of the first inner shell body passes through the outer flow path defined by the second inner shell body to be jetted from a second opening end of the outer shell body.

A compressor section for a gas turbine engine according to an example of the present disclosure includes, among other things, a low pressure compressor including a plurality of rotor blades arranged about an axis, a high pressure compressor, and a core flowpath passing through the low pressure compressor. The core flowpath at the low pressure compressor defines an inner diameter and an outer diameter relative to the axis. The outer diameter has a slope angle relative to the axis.

A piping assembly and a refrigeration system. The piping assembly includes: an inlet portion extending along an inlet axis; an outlet portion extending along an outlet axis, wherein a predetermined angle is formed between the inlet axis and the outlet axis; a transition portion being attached between the inlet portion and the outlet portion and defining a transition axis; a cavity extending from the inlet portion to the outlet portion through the transition portion; and a first straightening portion including a plurality of deflector plates attached to an inner wall of the cavity, wherein the first straightening portion includes at least a first deflector plate and a second deflector plate connected at an angle, and the first deflector plate and the second deflector plate are configured to extend in parallel with a part of the outlet axis and a part of the transition axis.

An air moving device includes a housing member, an impeller assembly, and a nozzle assembly. The nozzle assembly can include one or more angled vanes set an angle with respect to a central axis of the air moving device. The air moving device can output a column of moving air having an oblong and/or rectangular cross-section. A dispersion pattern of the column of moving air upon the floor of an enclosure in which the air moving device is installed can have an oblong and/or rectangular shape. The dimensions of the dispersion pattern may be varied by moving the air moving device toward or away from the floor, and/or by changing the angles of the stator vanes within the nozzle assembly.
