Morphology

solid-propellant + motor

The phrase is compositionally transparent: it denotes a motor that uses a solid propellant (solid + propellant) and follows a regular modifier + noun pattern, so the overall meaning can be inferred from the parts. Although technical, a B1 learner who knows the constituents ('solid', 'propellant', 'motor') would reasonably deduce it refers to a motor powered by a solid fuel.

Etymology

Solid-propellant motor comes from the idea that the engine uses a solid propellant — a hard block of 'fuel' placed inside the motor. Imagine a candle burning inside a tube to 'push' the rocket; that's why the name means a rocket engine that carries and burns its solid 'fuel'.
