According to an aspect, a bearing compartment includes a housing and a spring integrally formed with the housing. An oil passage is internally fabricated within the housing, and the oil passage extends into the spring. Further aspects can include a gas turbine engine with a bearing system and a method of manufacturing a bearing compartment.

Oil passage built into bearing compartment spring

A hybrid electric engine of an aircraft includes a compressor, a turbine operably connected to the compressor via a variable gear ratio gearbox and a combustor configured to drive the turbine via a flow of combustion products. An electric motor is operably connected to the variable gear ratio rear box and configured to input rotational energy into the gearbox. The input of rotational energy into the gearbox from the electric motor changes a rotational speed of one of the compressor or the turbine relative to the other of the compressor or the turbine.

An oil distributor is provided for a bearing chamber. The oil distributor includes an outer annular manifold, which is integrally formed with an interior surface of the bearing chamber and which defines a first interior cavity receptive of pressurized oil which defines a first interior cavity receptive of pressurized oil, an inner annular manifold, which defines a second interior cavity and comprises an interior facing surface defining holes respectively communicative with the second interior cavity and one or more support struts by which the inner annular manifold is supported within the outer annular manifold. Each of the one or more support struts defines interior lines by which the pressurized oil flows from the first interior cavity to the second interior cavity and to the holes.

A bearing compartment includes a housing having an upper housing portion and a lower housing portion, and a support structure fabricated within the bearing compartment. The support structure includes an upper portion within the upper housing portion and a spring section within the lower housing portion. The spring section includes a plurality of struts and is separable from the support structure for use as a spring within the housing.

Support structure and spring for bearing compartment

According to an aspect, a bearing compartment includes a housing integrally formed with a spring configured to deform in response to a force. The housing includes an overhang region that is supported by the spring during an additive manufacturing build process. The spring includes a plurality of struts that extend axially within the housing.

Spring damping for bearing compartment

According to an aspect, a support structure is integrally formed with a bearing compartment. The support structure includes a plurality of vertical supports and horizontal supports. The vertical supports and horizontal supports include one or more features to support machining of the bearing compartment and removal of the support structure from the bearing compartment.

Support structure for bearing compartment

Disclosed is an inlet system for a gas turbine engine that extends along a longitudinal axial centerline, the inlet system comprising: an inner dome, a shroud located axially aft and radially outward of the inner dome with respect to the centerline, a splitter nose located radially inward of the shroud with respect to the centerline, a first plurality of struts radially disposed between the shroud and the splitter nose with respect to the centerline, a second plurality of struts radially disposed between the splitter nose and a bearing with respect to the centerline, a plurality of inlet guide vanes radially disposed between the splitter nose and the bearing with respect to the centerline, and the plurality of inlet guide vanes axially aft of the plurality of second struts with respect to the centerline.

Gas turbine with oil warming anti-ice circuit

A cooling manifold has a plurality of pieces. The pieces extend in a circumferential direction to abutting flanges. The flanges are secured together at circumferential ends of each piece. Cooling channels are formed in between inner and outer walls. Air inlets are formed in the pieces with the air inlets delivering air in the interior. There are fingers on an outer periphery. The fingers are aligned within an air outlet. The air can be delivered into the inlet, cool the interior, and leave through the outlet extending to a main conduit. The main conduit is secured directly to an outer periphery of the cooling manifold.
