Abstract: A turbomachine has at least one rotor blade row designed for extremely high work coefficients (high-load), which—in its center section and/or averaged over the blade height—provides for an essentially swirl-free relative outflow. The respective rotor in its trailing edge area is essentially orientated in meridional direction, with the mean or averaged exit metal angle of the rotor blade ranging from −10 to +5 degrees.

Abstract: A propulsive force controlling apparatus controls a propulsion system attached to a hull of a marine vessel. The propulsion system includes a motor, a propulsive force generating member which receives a torque from the motor to generate a propulsive force, a clutch mechanism which is switched between a coupling state which permits transmission of the torque from the motor to the propulsive force generating member with virtually no slippage and a decoupling state which prohibits the transmission of the torque from the motor to the propulsive force generating member, and a clutch actuator which actuates the clutch mechanism. The propulsive force controlling apparatus includes a target propulsive force acquiring section which acquires a target propulsive force to be generated by the propulsion system, and a clutch controlling section which controls (via intermittent coupling control, for example) the clutch actuator on the basis of the target propulsive force acquired by the target propulsive force acquiring section.

Abstract: There is described a fluid flow concentrating device suitable, for example, for concentrating the flow of tidal waters or of wind, which comprises a hollow body closed at one end and open at the other. The body has a fixed circumferential wall composed of a plurality of fixed spaced vanes and a nozzle located at the open end of the wall. Fluid moving from outside the device through the vanes to the inside of the body creates a vortex within the body and a fluid flow axially of the body through the nozzle. In certain preferred embodiments a turbine is located for rotation in a direction opposite to the direction of rotation of the vortex about a vertical axis, centrally within the nozzle downstream of the fluid flow. The turbine can be used to drive a generator or a motor to, for example, propel a marine craft, or, the augmentor can be used on a aircraft to assist the lift of a wing, or, in another application, can be used with a jet turbine engine to improve both the intake to and the thrust from the engine.

Abstract: A foldable electric fan, comprising: a fan head, a support tube and a base, a turnover mechanism for turning the fan head up or down is provided between the top of the support tube and the fan head, is disclosed. Further, the base is foldable, and the electric fan can be arranged into a desk fan or a floor fan by turning the fan head up or down, and can be used for several different purposes in more broad fields. The fan head and the base of the electric fan can be folded-up, which reduces the space it occupies and cuts down the cost of package and transportation. Moreover, the foldable electric fan effectively reduces the inconvenience of traditional electric fans which need to be detached into several parts during package and transportation, and then assembled together for use.

Abstract: The fan impeller (10) comprises a hub (14) and blades (12) extending radially outward from the hub, the blades having a flattened airfoil profile cross section with a leading edge (24) and a trailing edge (26) between which a chord is defined. The blade (12) has a relative thickness that reached its maximum value (Emax) in the first quarter of the length of the chord measured from the leading edge (24), the relative thickness being defined by the ratio between the thickness of the blade and the length of the chord. The invention finds an application particularly in motor vehicle engine cooling fan impellers.
