In an aircraft a fluid handling device having a plurality of separated fluid handling working chamber groups with separated fluid outlets of each of said working chamber groups. Each fluid handling working chamber group has a plurality of individual fluid-handling spaces which together deliver the discharged fluid into the common fluid outlet of the respective working chamber group. Each working chamber group has an actuator means for actuating the respective displacement means, which move the working fluid into and out of the respective individual fluid handling spaces. Each fluid outlet of each working chamber group is connected by a respective uninterrupted fluid line directly to an associated fluid motor for revolving the same, while at least one propeller is associated with each respective fluidmotor to be driven by the same. The actuator means of more than one working chamber group are connected together for assuring equal or at least at all times proportionate actuation of the displacement means of the plurality of the working chamber groups. Thus equal or at least at all times proportionate rate of flow are forced out of the said separated fluid outlets through said fluidlines for forcing the said fluidmotors to revolve with equal or at least at all times proportionate rotary velocity of said fluid motors and propellers, whereby fluidstreams of equal or at least at all times proportionate thrust are generated and applied in substantial symmetric locations on the body of the craft to drive the same steadily in the desired direction.
