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....
A noise suppressing air inlet for use in combination with a gas turbine engine that is encased in a housing and includes a compressor stage, said air inlet comprising: a generally tubular outer cowling for forming a forward end of said engine housing and having an annular leading edge, said outer cowling having an inner wall and an outer wall with said inner wall defining an airflow duct for directing airflow to said compressor stage, at least a portion of said inner wall a sound absorbing surface; a generally tubular inner cowling having an annular lead...
