Structural metering plate

摘要

A turbine engine trailing edge box utilizes a metering plate for creating a pressure differential across the trailing edge box and to support the trailing edge box. The metering plate creates a pressure drop from the front to the rear of the trailing edge box resulting in a film of cooling air on the surface of a flameholder. Slots for receiving the metering plate are located in corrugations formed on the trailing edge box. Once within the slots, force is applied to the metering plate as a result of airflow through the engine to maintain the metering plate within the slots.
