A fluid supply system includes a fluid delivery system, a sensor positioned to acquire data regarding an operating characteristic and/or a component characteristic of the fluid delivery system, and a monitoring system coupled to the sensor. The fluid delivery system includes a pump having an inlet configured to receive a fluid, an outlet configured to provide a pressurized fluid to a fluid output, a housing defining a chamber that couples the inlet to the outlet, an impeller disposed within the chamber, and an input coupled to the impeller. The input is configured to facilitate driving the impeller to pressurize the fluid received at the inlet to generate the pressurized fluid within the chamber. The monitoring system is configured to determine a health level of a component of the fluid delivery system based on the data and provide a notification in response to the health level not satisfying a threshold.

A system for controlling the clearance distance between an impeller blade tip of a centrifugal compressor and a radially inner surface of an impeller shroud in a turbine engine. The system comprises a high pressure air source, an air piston mounted between an engine casing and the shroud and adapted to receive high pressure air from the high pressure air source, a mounting arm coupling the shroud and air piston, and a slidable coupling adapted to allow axial movement of the shroud and joining the shroud to an axial member.

Flow control devices and structures designed and configured to improve the performance of a turbomachine. Exemplary flow control devices may include various flow guiding channels, ribs, diffuser passage-width reductions, and other treatments and may be located on one or both of a shroud and hub side of a machine to redirect, guide, or otherwise influence portions of a turbomachine flow field to thereby improve the performance of the machine.

A Centrifugal compressor impeller including a plurality of blades extending from a hub, each blade having a first wall defining a pressure side of the blade, and a second wall defining a suction side of the blade, and a free end defining a tip of the blade, the tip presenting a raised rim aligned to the first wall, the second wall of the blade being at least partially aligned with a surface of the tip free from the raised rim.

A centrifugal blower includes: a centrifugal fan, which includes a shroud ring; and a case. The case includes a cover portion that covers a surface of the shroud ring located on one side in an axial direction. The cover portion includes a recess formed in a cover opposing surface, which is opposed to the shroud ring, and the recess is shaped in a form of a circle. The shroud ring includes at least one projection that is formed in a ring opposing surface, which is opposed to the cover portion. A gap is formed between the cover portion and the shroud ring. A shortest distance between a radially inner end part of the shroud ring and the cover portion is set to be larger than a shortest distance between a surface of the projection and a surface of the recess.

A compressor for a turbine engine includes a shroud having a grooved section including a plurality of groove segments extending radially into a shroud surface. A rotor assembly rotatably supported in the shroud includes a rotor hub and a plurality of rotor blades. Each rotor blade extends radially from the rotor hub and terminates at a blade tip, which is spaced from the shroud surface by a tip gap and defines a non-constant clearance region between a leading edge position and a medial chord position along the blade chord at the minimum tip clearance. The rotor blades generate an aft axial fluid flow through the shroud and the grooved section is formed in the shroud surface upstream of the medial chord positon within the non-constant clearance region for resisting a reverse axial fluid flow through the tip gap when the compressor section is operated at near stall conditions.

An impeller for use in a pump assembly for a fluid circuit of an engine of a vehicle comprises a plurality of projections provided at radially spaced locations relative to a rotational axis of the impeller, the impeller being rotatable relative to a housing of the pump assembly. The projections extend axially from a surface of the impeller and circumferentially about the rotational axis of the impeller. At least one of the projections is configured to be at least partially received in a recess provided in the housing such that a flow path is provided by the projection and the respective recess, wherein the flow path provides a tortuous flow route for fluid between an inlet and outlet of the pump assembly so as to restrict flow of fluid along said flow path and thereby minimise flow of fluid from the outlet back towards the inlet in a direction opposite to the intended direction of flow.

A vane stage with a longitudinal axis designed to be fitted in a turbine engine compressor. The van stage has an annular row of mobile vanes arranged upstream from an annular row of stator vanes. The annular row of stator vanes has a radially internal annular platform bearing radial blades, an upstream annular portion of which is arranged upstream from the blades and is surrounded radially outwards by a downstream annular portion of an annular platform of the upstream row of mobile vanes. The upstream annular portion of the annular platform of the annular row of stator vanes has a radially external annular face from which fins extend, which are distributed around the longitudinal axis and extend radially outwards towards the downstream annular portion of the platform of the annular row of mobile vanes.

One exemplary embodiment of this disclosure relates to a system having a static segment with a circumferentially extending slot. The system further includes a retention clip partially received in the slot, and partially contacting a circumferential end of the static segment.
