摘要：
A gas turbine engine includes a first airflow structure (23) and a second airflow structure (36) disposed aft of the first airflow structure (29). The second airflow structure (23) includes a leading edge region (72). A thickness of the leading edge region (72) is based on a thickness of a wake (64) in the airflow produced by the first airflow structure (23) when the airflow passes between the first airflow structure (23) and the second airflow structure (36).
