I have a long running argument with a person about the 'pod' looking things under the wings of the A380 (and other commercial jets). What i am talking about are the 5 or so 'pod' looking things that sit under each wing. I suspect that they encase hydraulics.
I believe they encase the motors for the flaps and slats. In that case so they are aerodynamic 😀
Jon pretty much hit it. They are a part of the engine system that help run the flaps, slats, spoilers, and the rest of the systems in the wings.
They also house the hinges associated with flap deployment. They could also theoreticaly help the airflow under the wings, not unlike flow fences.
Thanks for your help guys!!
