Beschreibung
Zusammenfassung:	The present invention provides a turbine vane for a gas turbine engine (10). The turbine vane (30) may include a composite airfoil structure (46). The composite airfoil structure (46) may have an opening. The turbine vane (30) may include a spar (48). The spar (48) may have a body (58), which may be disposed within the opening. A standoff structure (68) may be disposed within the opening. In some non-limiting embodiments, a cooling air gap may be defined between the body and an internal surface of the composite airfoil structure (46).
