초록

A noise-suppressing air inlet having two coaxially arranged airflow channels to supply inlet air to a gas turbine engine is disclosed. The outer airflow channel has an annular cross-sectional geometry and is formed between the inner wall of a tubular outer cowling which forms the forward portion of the engine housing and the outer wall of a tubular inner cowling that is coaxially mounted within the outer cowling. The inner airflow channel is formed between the inner wall of the inner cowling and a forward projecting central hub of the gas turbine engine....
