Abstract: A gas turbine engine (10) includes a compressor section, a turbine section, and an accessory gearbox (100). A turning unit (200) for the gas turbine engine includes an output assembly (204) configured to be mechanically coupled to the gas turbine engine, and an electric motor (202). The electric motor is operable to rotate, through the output assembly, one or more components of the compressor section or the turbine section at a rotational speed less than about fifty revolutions per minute during a shut-down condition of the gas turbine engine.

Abstract: A heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a housing defining a heat exchange plenum having a first fluid inlet and a first fluid outlet separated along a transverse direction. A plurality of heat exchange banks pass through the heat exchange plenum between a top side and a bottom side of the housing substantially along a vertical direction, each of the heat exchange banks comprising a plurality of heat exchange tubes. A plurality of collector manifolds are positioned at the top side and the bottom side of the housing, each collector manifold defining one or more connecting ports providing fluid communication between adjacent heat exchange banks.
