A propulsion system for an aerial vehicle with a suppressed radar observability comprises one or more rotors (100) with rotor blades (no); a fuselage (200), a tubular channel structure (300), and a shielding structure (400). The fuselage (200) provides a support for the one or more rotors (100) and at least one integrated engine (210) to drive the one or more rotors (100), wherein the rotor blades (110) protrude radially outwards from the fuselage (200). The tubular channel structure (300) circumferentially extends around the fuselage (200) and covers the protruding rotor blades (110), wherein the tubular channel structure (300) includes an inlet (310) and an outlet (320) between which the rotor blades (110) are arranged to drive a propulsion airflow (F). The shielding structure (400) is formed at the inlet (310) and/or at the outlet (320) for radar signals to suppress radar detection of the rotor blades (110).
