64.6 Turbine Engine Inlet Systems

64.6.2 Describe the purpose, design and principles of operation of the engine inlet duct. 

Air Inlet Ducts:

While technically part of the airframe, the air inlet ducts are crucial for engine operation and are thus included.

These ducts ensure the compressor receives a consistent, undisturbed flow of subsonic air, which is essential for efficient gas turbine engine function.

The design and construction of these ducts are meticulously matched to the engine's needs.

Any necessary repairs must be executed with precision to prevent airflow distortion, preserving optimal engine performance.

64.6.4 Describe and explain the purpose of a subsonic divergent inlet duct.
