A propulsion device for exerting thrust to a fluid, which comprises a central hub (10, 110, 210) having a front end (11) and a rear end (12) and being rotational about a rotational axis (A) extending longitudinally between the front (11) and rear (12) ends, and at least two propulsive arrangements (20, 120, 220) which protrude radially from the hub (10, 110, 210) and which are evenly distributed about the circumference of the hub (10, 110, 210). Each propulsive arrangement (20, 120, 220) comprises a front propulsive element (30) which extends from a front inner end (31) to a front outer end (32). A rear propulsive element (40) extends from a rear inner end (41) to a rear outer end (42). An outer guide element (60) extends from the front outer end (32) to the rear outer end (42). An inner guide (70) element extends from the front inner end (31) to the rear inner end (41) at an inner guide element distance (IG). An elongate front distance member (35) and an elongate rear distance member (45) extend radially from the hub (10) to the inner guide element (60). At least one intermediate propulsive element (50) is arranged between the front (30) and rear (40) propulsive elements and extends radially from the inner guide element (70) to the outer guide element (60). The inner guide element (70), the front distance member (35), the rear distance member (45) and the periphery of the hub (10) define an open space allowing free passage of the fluid.
