Publication number: 20120315131Abstract: An axial turbocompressor having an annular compressor passage which is arranged concentrically around a rotational axis, is delimited radially on the outside by a passage wall, and in which rotor blades, which may be assembled to form a ring, are arranged in a rotatably mounted manner around the rotational axis, is provided. The free-ending tips of the rotor blades lie opposite the passage wall in each case, forming a gap, and the passage wall, in the axial section of the tips, at least partially has a wall structuring and wherein a bleed opening of a bleed passage is provided in the passage wall for the tapping of medium flowing in the compressor passage. In order to enable an exceptionally efficient bleed of medium flowing in the compressor passage, the bleed opening is located in the wall structuring.Type: ApplicationFiled: June 5, 2012Publication date: December 13, 2012Inventor: Dirk MERTENS

Patent number: 8317463Abstract: A fan apparatus includes a blower defining an air outlet at a lateral side thereof, an annular guiding rail and a fastener connecting the blower with the guiding rail. The guiding rail defines an annular groove therein. One end of the fastener is received and slidable in the groove of the guiding rail, whereby the fastener can slide in the groove along a circumferential direction of the guiding rail. The other end of the fastener is connected with the blower, and thus the blower is rotatable with respect to the guiding rail such that an orientation of the air outlet of the blower can be easily regulated.Type: GrantFiled: October 18, 2009Date of Patent: November 27, 2012Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Zhen-Xing Ye

Patent number: 8313285Abstract: An example turbofan engine sound control system includes a core nacelle (12) housing a compressor and a turbine. The core nacelle is disposed within a fan nacelle (34). The fan nacelle includes a turbofan. A bypass flow path downstream from the turbofan is arranged between the two nacelles. A controller (50) is programmed to manipulate the nozzle exit area to control sound propagating from the engine. In one example, the controller manipulates the nozzle exit area using hinged flaps (42) to control engine sound. The hinged flaps open and close to adjust the nozzle exit area and the associated bypass flow rate.Type: GrantFiled: October 12, 2006Date of Patent: November 20, 2012Assignee: United Technologies CorporationInventors: Wesley K. Lord, Zbigniew M. Grabowski

Patent number: 8303242Abstract: A hydropower generating turbine having an impeller housing disposed to receive water, at least one impeller disposed within the impeller housing, at least one adjustable duct pivotally connected to the impeller housing, and, where the duct has a plurality of duct leafs, wherein the duct leafs articulate and cause the duct to converge and diverge for selectively disposing a fluid about the impeller. The ducts may be inflow or outflow ducts, and the turbine may react to a change in the fluid and alter the shape of the impeller. Further, the turbine may have an automated controller where variable change in the flow is detected by a sensor and transmitted to the automated controller to cause a directional shift in the multidirectional turbine.Type: GrantFiled: December 14, 2011Date of Patent: November 6, 2012Assignee: Hydro Green Energy, LLCInventors: Wayne F. Krouse, Frederick E. Becker, Andrew R. Provo

Patent number: 8277175Abstract: A combustion air supply blower includes a blower housing having a housing body and housing cover. The cover is removably attached to the housing body and generally provides access to a motor and fan assembly including a fan and a motor. The motor and fan assembly is removably mounted within the housing body and is captured between the housing body and the housing cover such that, upon removal of the housing cover, the motor and fan assembly is exposed and may then be lifted out of the housing body for easy maintenance, repair, and/or replacement of any portion of the motor and fan assembly. Alternatively, upon removal of the housing cover, the motor and fan assembly may be accessed while remaining within the housing body to complete any maintenance and/or repair of the motor and fan assembly.Type: GrantFiled: April 1, 2008Date of Patent: October 2, 2012Assignee: RBC Horizon, Inc.Inventors: Bobby D.
