Morphology

rudder + blade

The meaning is directly derivable from combining 'rudder' (a steering device) with 'blade' (a flat vane); together they denote the flat vane part of a rudder. This noun-noun composition follows normal English compounding patterns and is cross-linguistically transparent, so a B1 learner who knows both words would readily infer the MWE's meaning.

Etymology

The noun rudder blade names the flat, vertical part of a rudder that moves through the water like a fin or knife. When the blade turns it pushes the water and makes the boat or plane change direction, so the name gives a clear picture of 'to steer'.
