propellerless
Lacking spinning blades
Propellerless describes aircraft or watercraft that lack propellers for propulsion.
The term typically distinguishes jet-powered planes from propeller-driven ones, or boats using jet drives rather than traditional screws: The propellerless design made the craft quieter and safer around swimmers.
