摘要： A fan duct seal for a gas turbine engine has at least one seal body with a hollow center. A first opening is formed in the seal body that is in fluid communication with the hollow center. The first opening is configured to receive fan air flow. A second opening is formed in the seal body that is in fluid communication with the hollow center such that cooling flow enters the first opening, moves through the seal body and exits from the second opening. A fan duct for a gas turbine engine and a method of cooling a fan duct seal assembly are also disclosed.

摘要： The present invention has an object of providing a sealing structure for a casing that suppresses the deformation of a center plate of a laminated gasket on a partition wall and ensures the compression amount of a bead on the partition wall, without the center plate being thickened. The object is achieved by a sealing structure including: a case 2, the interior of which is partitioned by a partition wall 25 into an upstream chamber 23 and a downstream chamber 24; a cover 3, which forms a flow path for a fluid that causes the upstream chamber 23 and the downstream chamber 24 to be communicated inside; and a laminated gasket 4, in which a first gasket 41, a center plate 43, and a second gasket 42 are laminated, and that is provided between a butting surface 22a of the case 2 and a butting surface 32a of the cover 3, in which the first gasket 41 and the second gasket 42 respectively include beads 41b and 42b along the butting surfaces 22a and 32a, and the first gasket 41 and the center plate 43 respectively include partition-wall sealing portions 41a and 43a along the partition wall 25, the partition-wall sealing portion 41a of the first gasket 41 includes the beads 41b, and the cover 3 is provided with a contact portion 34 that applies a contact force to the partition-wall sealing portion 43a of the center plate 43.

摘要： In a fan motor, a stator unit of a motor that rotates an impeller includes an annular stator, the center of which is positioned on a central axis, and a housing including an accommodating portion that accommodates a part of a resin portion covering at least a part of the stator. At least one of a bottom face of the accommodating portion oriented to the stator in the axial direction and an inner side face of the accommodating portion oriented to an inner side in the radial direction is provided with a plurality of stepped portions. The stepped portions are different from each other in length in the axial direction when provided in the bottom face, and/or in length in the radial direction when provided in the inner side face. The bottom face, the inner side face, and the stepped portion are covered with the resin portion.

摘要： An impeller includes a shell having a plurality of blades. The shell may also define a cavity. The impeller may further include a backplate that engages at least a portion of the shell. The backplate can include a post which can be coupled to the impeller through a fastener such as a threaded nut. The backplate can be thereafter clamped to the impeller shell. Seals can be provided in the impeller, such as in the backplate. The backplate and impeller shell can be piloted onto each other. In some forms splines can be used to secure the backplate to the impeller shell.

摘要： A gas turbine engine includes a circumferential row of blades, with the blades having respective blade tips. A seal is disposed about the blades. The seal has an abradable layer which the tips of the blades, at times, rub against when the blades rotate. The rubbing produces a maximum temperature at the abradable layer. The abradable layer includes a metal matrix and microballoons dispersed in the metal matrix. The microballoons are formed of a glass that has a glass transition temperature that is approximately 50° F. to 300° F. greater than the maximum temperature.

摘要： A built-in electric air pump for an inflating object includes a pump casing, a switch hand-wheel, a connection pipe, an air passage switching device, an air pump, and an air valve and a power switch. The pump casing includes a box-shaped chamber. The switch hand-wheel is provided at an external lateral side of the panel. The air passage switching device is provided with an internal pipe having a first opening and a second opening respectively arranged at an upper end and a lower end of the internal pipe. The first opening communicates with outside of the inflating object, and the second opening communicates with the air valve. A diaphragm is provided inside the internal pipe. A first venting hole and a second venting hole are respectively provided on internal walls at two sections of the internal pipe above and below the diaphragm. An external sleeve is provided outside the internal pipe. The lower end of the external sleeve is fixedly connected to the pump casing. The lower end of the external sleeve correspondingly communicates with the air valve. A wall of the external sleeve is provided with an air outlet communicating with an air inlet of the air pump and an air inlet communicating with an air outlet of the air pump. An upper end of the connection pipe is connected to and communicated with the switch hand-wheel, and the lower end of the connection pipe is muff-coupled with the upper end of the internal pipe. The diaphragm of the internal pipe contacts a valve rod of the air valve such that the valve is opened by an applied external force and the diaphragm and the value are moved together.
