Abstract
A turbine vane assembly includes a flow path ring, an airfoil heat shield, and a seal. The flow path ring is made of ceramic matrix composite materials. The airfoil heat shield is made of ceramic matrix composite materials. The seal resists passage of gases through a gap formed between the flow path ring and the airfoil heat shield along an interface at the airfoil aperture.
