Morphology
The meaning is directly compositional: a blade that belongs to or is part of a rotor, so knowing 'rotor' (rotating part) and 'blade' (flat/curved vane) makes the combined meaning clear. This noun–noun compound follows a common cross-linguistic pattern of modifier + head, so a B1 learner familiar with both constituents should readily understand it.
Etymology
The compound rotor blade is a plain name that shows the idea: a rotor is the part that 'turns' and a blade is a long, thin piece that moves through the air. So a rotor blade is a long, shaped 'blade' that turns to give 'lift' to a helicopter.
