An electric-motor radiator fan of a motor vehicle has a fan shroud with a motor holder. An electric motor is inserted in the motor holder. A heat shield plate is arranged on the end side of the electric motor. The heat shield plate is placed onto a projection of the motor holder by way of a cut-out, and the heat shield plate is pivoted around the projection, which forms an axis of rotation, in such a way that the heat shield plate is forced at least in sections into at least one holding contour of the motor holder in a positive locking and/or friction-locking manner.

The invention concerns a turbine nozzle, comprising a plurality of angular nozzle sectors (6) each angular sector (6) comprising two inner and outer platform sectors, connected together by a plurality of radial blades (63), each inner platform sector (62) being rigidly attached to a radially inner foot (621), this nozzle comprising an annular collar (5) on which the nozzle angular sectors are fastened end-to-end circumferentially, this collar (5) comprising a cylindrical ring (50) the radial inner face (51) of which comprises an abradable material (53). This nozzle is characterised in that the radially inner foot (621) of each inner platform sector comprises a radial tab (622) and in that the annular ring (50) comprises a plurality of L-shaped pads (55), each pad delimiting a slot (553) for receiving the tab (622), so as to ensure the fastening by coupling of the collar on each nozzle angular sector.

A turbine assembly for use with a gas turbine engine includes a bladed wheel assembly, a vane assembly, and an inner seal. The bladed wheel assembly is adapted to interact with gases flowing through a gas path of the gas turbine engine. The vane assembly is located upstream of the bladed wheel assembly and adapted to direct the gases at the bladed wheel assembly. The inner seal is configured to block gases from passing around the vane assembly.

A pump cartridge comprising an external housing including a lateral wall, a first fin extending from a first side of the lateral wall, and a second fin extending from a second side of the lateral wall. The second side of the lateral wall may be opposite the first side of the lateral wall, such that the fins are on opposite sides of the lateral wall. The pump cartridge may be part of a pumping system further comprised of a chassis comprising a pump basin including an interior side wall, a first tab extending inwardly from the interior side wall, and a second tab extending inwardly from the interior side wall and opposed to the first tab. The first fin of the cartridge is reversibly engageable with the first tab of the chassis and the second fin of the cartridge is reversibly engageable with the second tab of the chassis.

Turbomachines and methods for coupling first and second turbomachine components are provided. The components include castellated flange arrangements that provide an improved retention method for retaining the components that is far superior in than bolts and nuts, especially for massive unbalance loading.

A unitized build assembly for a gas turbine engine includes an exhaust duct, a hot section with a locking structure and including a combustor and turbine section. The hot section at least partially circumferentially surrounds the exhaust duct. The build assembly includes a compressor section with an interface structure and is proximal to the hot section. The hot section at least partially circumferentially surrounds at least part of the compressor section and the locking structure is configured to engage the interface structure to limit movement of the hot section relative to the compressor section.

A fan for a gas turbine engine is provided. The fan includes a plurality of fan blades, a disk, and a trunnion mechanism for attaching the fan blades to the disk. The disk can be formed of a plurality of individual disk segments, with the trunnion mechanism attaching one of the plurality of fan blades to a respective disk segment. A retention member is also provided. The retention member includes a means for catching a portion of the trunnion mechanism should a primary attachment system of the trunnion mechanism fail.

The disclosed subject matter concerns with an apparatus for mounting a ceiling fan to a support surface such as a ceiling. The apparatus includes a mounting bracket configured to support the ceiling fan; at least one bracket engaging surface; a canopy cover configured to be detachably mounted to the mounting bracket such that the ceiling fan is disposed below the canopy cover; and at least one cover engaging surface configured to move along the bracket engaging surface in a mounting direction. The apparatus further includes an arresting mechanism, operable as a result of the canopy cover having been moved relative to the mounting bracket in the mounting direction to a required extent, configured to releasably restrict movement of the cover engaging surface relative to the bracket engaging surface in a direction opposite to the mounting direction.

A pump assembly (1) includes a rotor axle (45) extending along a rotor axis (R), an impeller (12) fixed to the rotor axle (45), a pump housing (11) accommodating the impeller (12), and a drive motor including a stator (17) and a rotor (51). The rotor (51) is fixed to the rotor axle (45) for driving the impeller (12). A rotor can (57) accommodates the rotor (51). The rotor can (57) include a rotor can flange (63). A stator housing (13) accommodates the stator (17). The stator housing (13) is secured to the pump housing (11) by a bayonet ring (113). The bayonet ring (113) is resiliently spring-loaded for axially biasing the stator housing (13) towards the impeller (12) against the pump housing (11).
