Beschreibung
Zusammenfassung:	Apparatus and systems for a cooled gas turbine engine flowpath component are disclosed. In some embodiments, the flowpath component includes a spar and a coversheet. The spar may include a suction-side wall extending from a leading edge to a trailing edge and a pressure-side wall extending from the leading edge to the trailing edge, each wall having an outer surface. The coversheet may be positioned on the spar to at least partially enclose the spar, the coversheet having an engagement surface positioned to face the outer surface of the suction-side wall and the outer surface of the pressure-side wall. The spar and the coversheet cooperate to form a number of passageways configured to cool the flowpath component.
