Morphology

single-rotor + helicopter

The phrase is fully compositional: 'single' (one) modifies 'rotor' (rotating blade assembly) to indicate number, and that compound modifier describes the kind of 'helicopter' (an aircraft lifted by rotors). This modifier–noun construction follows a common and predictable pattern in English (and similar patterns across other languages), so a B1 learner who knows the constituent words can readily infer the meaning.

Etymology

Single-rotor helicopter is a helicopter with one big spinning blade on top and a small tail rotor at the back. Picture the top blade giving 'lift' to rise and the tail rotor stopping the body from turning, which is why the name means a helicopter with one main rotor used to lift and keep it steady.
