  • Blade with optimized vibration behavior
    Patent number: 6503053
    Abstract: A blade with optimized vibration behavior for turbomachinery components in an axial-type construction having a solid, thin and elongated blade body, the blade, at a distance from both a radially inner blade body end and a radially outer blade body end, having at least one plate-like rib which is disposed in an upright position on the blade body surface and is oriented in a neutral manner with regard to the flow and is also integrally connected to the blade body on one of the suction and pressure sides of the blade.

  • Nozzle ring for a gas turbine
    Patent number: 6431830
    Abstract: A worked nozzle ring for a gas turbine, in particular an aircraft engine, having at least one shroud and at least one blade sheet arranged thereon, whereby, in order to create a worked nozzle ring that is easy to manufacture, the blade sheet comprises, at the frontal side, at least one two-dimensionally profiled connecting space region that is placed in a profiled opening formed in the shroud by beam cutting and is connected therewith.

  • Device for controlling the throat areas between the diffusor guide vanes of a centrifugal compressor of a gas turbine engine
    Patent number: 4740138
    Abstract: This device provides the diffusor guide vanes with bypass ducts which establish communication between the pressure and suction sides, which can be sealed by means of shut-off elements, which take the form of bimetal components or at least are connected to such a component, and which are deformed flap-fashion as a function of temperature.

  • Apparatus for controlling the flow of leakage and cooling air of a rotor of a multi-stage turbine
    Patent number: 4571937
    Abstract: A muilti-stage turbine having shrouded turbine blades which has a stationary guide grid arranged between the rotor shroud and the turbine casing. By virtue of the construction of the guide grid, leakage and cooling air (escape air) of the rotor blade can be adapted to the low whirl of the main stream passing through the rotor to effectively prevent misaligned entry into the following turbine stage.
