Compressor stator vane, axial flow compressor, and gas turbine
Within a compressor case, a plurality of stages of high-pressure compressor stators are disposed alternately with a plurality of stages of high-pressure compressor rotors along an axial direction. Each stage of the high-pressure compressor stators includes a plurality of compressor stator vanes. Each of the compressor stator vanes has, on a camber line, a camber reference point in which (θ−θe)/θk is 50% (θ, θe and θk represents a metal angle, an exit metal angle and a camber angle, respectively). In a vane-shaped cross-section, a distance from a leading edge to the camber reference point is set to a 26-38% chord. |

Superplastic forming
An aerofoil structure with a hollow cavity is manufactured by diffusion bonding and superplastic forming. Outer panels are formed of a first material; a membrane is formed of a second material. Stop-off material is applied to preselected areas on at least one side of the membrane or of one of the panels so as to prevent diffusion bonding between the panels and the membrane at the preselected areas. The panels and the membrane are arranged in a stack and a diffusion bonding process is performed to bond together the first and second panels and the membrane to form an assembly. A superplastic forming process is performed at a forming temperature to expand the assembly to form the aerofoil structure. The forming temperature is selected so that the second material undergoes superplastic deformation at the forming temperature and the first material does not undergo superplastic deformation at the forming temperature. |

Methods and apparatus for detecting and preventing compressor surge
Methods and apparatus are disclosed for detecting and preventing compressor surge. A transmitter determines a derivative process value of a compressor. A controller obtains the derivative process value from the transmitter. The transmitter is separate from the controller. The controller compares the derivative process value to a threshold value. The threshold value is indicative of the initiation of a surge event in the compressor. In response to determining that the derivative process value fails to satisfy the threshold value, the controller actuates a valve operatively coupled to the compressor to enable an additional derivative process value of the compressor determined by the transmitter to satisfy the threshold value. |

Performance map control of centrifugal pumps
The present invention relates to a method for controlling a pump, in particular a centrifugal pump, during pumping of a liquid, comprising the following steps: fixing a setpoint value of a flow rate of the pump; measuring an inlet pressure of the liquid upstream of the pump and an outlet pressure of the liquid downstream of the pump; determining a setpoint value of a rotational speed of the pump from a performance map of the pump, wherein the fixed setpoint value of the flow rate and a difference between the outlet pressure and the inlet pressure are incorporated into the performance map as input values; and setting the rotational speed of the pump to the setpoint value of the rotational speed. Furthermore, the invention relates to a corresponding device for controlling a pump. |

Conical screw machine with rotating inner and outer elements that are longitudinally fixed
A conical screw compressor or pump comprises an inner element configured to rotate around a first axis and an outer element configured to rotate around a second axis. An outer surface of the inner element and an inner surface of the outer element comprise cooperating grooves and teeth that intermesh on rotation. The first axis and the second axis are each stationary and the first axis is inclined relative to the second axis. The inner element and the outer element are configured to be, in operation, synchronously rotated, thereby to reduce or eliminate force exerted by the inner element on the outer element or vice versa. |
