    Abstract: A gas turbine engine component according to an example of the present disclosure includes, among other things, a wall between first and second wall surfaces. The wall defines at least one cooling passage extending between an inlet along the first wall surface and an outlet along the second wall surface. The outlet has an upstream edge and a downstream edge with respect to a general direction of flow through the at least one cooling passage. The wall defines a plurality of crenellation features along at least the upstream edge. The upstream edge has a first profile established by the plurality of crenellation features, and the downstream edge has a second profile that differs from the first profile. A method of cooling is also disclosed.

    Abstract: A cooling system for a gas turbine engine comprises a passage capable of receiving cooling air, a compartment radially adjacent thereto and axially aligned therewith, an opening therebetween, a valve within the opening, and a heat exchanger received in the compartment. The valve is moveable between a maximum open position and a minimum open position for increasing or decreasing airflow from the passage into the compartment. At the valve minimum open position, a leakage path is provided between the passage and the compartment, whereby cooling air is capable of passing from the passage to the compartment and toward the heat exchanger at all valve positions. A gas turbine engine is also disclosed.
