Abstract: An inlet frame and a method of additively manufacturing the same are provided. The inlet frame includes a forward annular body spaced apart from a rear annular body to define an inlet passageway in fluid communication with a compressor inlet. The inlet frame may define integral wash manifolds and discharge ports for directing a flow of wash fluid directly through the compressor inlet. In addition, inlet frame may define one or more integral annular heating plenums in fluid communication with a hot air source for heating regions of the inlet frame that are prone to icing conditions.
