Aircraft Adapter

Similar to what we discussed earlier about duct reducers in HVAC systems, in aviation, there might be adapters or connectors designed to transition between different sizes of air ducts within the aircraft.

To get more specific information about an aircraft duct adapter, it would be helpful to know the context or the specific application you are referring to. Additionally, consulting the aircraft's documentation or contacting the manufacturer or relevant aviation authorities would provide more accurate details about the components used in the specific aircraft model.
