Claims16
An airfoil assembly defining a primary airflow path for a turbine engine, the airfoil assembly comprising:
- a platform at least partially defining a secondary airflow path fluidly coupled to the primary airflow path, the platform having an upper platform face at least partially defining the primary airflow path;
- an airfoil extending from the platform and into the primary airflow path, the airfoil having an airfoil outer wall defining an airfoil pressure side and an airfoil suction side;
- and
- a deflector provided along a portion of the platform axially forward of the airfoil, the deflector extending into the secondary airflow path, the deflector having:
- an axially forward edge provided within the secondary airflow path;
- an axially aft edge provided upstream of the axially forward edge;
- and
- a deflector wall defining a concave side and a convex side and extending between an axially forward edge and an axially aft edge;
- wherein the deflector is oriented such that the concave side corresponds to the airfoil pressure side.
