Manifold for gas turbine

A turbine engine, comprising;

• a gear assembly;
• a mounting plate having an interface configured for attachment to a gear housing;
• a flow plate attached to the mounting plate and configured to provide a plurality of flow passages between the mounting plate and flow plate;
• at least one fluid inlet configured to receive fluid from a supply;
• and
• at least one fluid outlet configured to direct the fluid into the gear housing,
• wherein the flow plate comprises a ring-shaped structure with a center opening defining a center axis and a first ring portion defined by a first inner peripheral surface extending circumferentially about the axis and a first outer peripheral surface spaced radially outwardly relative to the first inner peripheral surface,
• wherein the mounting plate comprises a notch-shaped structure with a center opening concentric with the center axis and a second ring portion defined by a second inner peripheral surface extending circumferentially about the axis and a second outer peripheral surface spaced radially outwardly relative to the second inner peripheral surface, the second outer peripheral surface having a plurality of radially extending tabs interspersed by notches, the radially extending tabs configured for attachment to the gear housing and
• wherein the plurality of flow passages comprises at least a first flow passage formed adjacent to the first and second inner peripheral surfaces and a second flow passage formed adjacent to the first and second outer peripheral surfaces, the first and second flow passages extending circumferentially around the first and second ring portions to at least partially surround the central axis,
• wherein the at least one fluid inlet is disposed on one of the plurality of radially extending tabs,
• wherein one of the mounting plate and the flow plate comprises a first groove and a second groove, wherein the first groove and the second groove are defined along a diameter relative to the central axis and
• wherein an other of the mounting plate and the flow plate comprises a first engagement member installable in the first groove and a second engagement member installable in the second groove.
