Abstract

The present invention is directed to methods for constructing a flange on a pipe using an additive manufacturing process, such as directed energy deposition, powder bed fusion, friction-stir, or diode laser cladding. The flange can be constructed on a pipe comprising an oxide dispersion strengthen or nickel-based alloys, in particular a precipitation strengthened nickel-based alloy, such that the pipe maintains its inherent mechanical and metallurgical properties, including hardness, tensile strength, yield strength, fracture toughness, creep strength, fatigue, which would otherwise be reduced based upon typical welding of a flange to the end of the pipe. The flange can be constructed around the exterior of a pipe at the end of the pipe to allow use of the flange in connecting the pipe via bolting to other piping components, such as another pipe with a corresponding flange, a valve flange, a pump flange, or any other type of flange.

Abstract

The invention provides various designs of an apparatus and method for attemperating a gas stream temperature. The apparatus of the present invention provides a body through which a gas stream passes that permits, as desired, a second gas, such as gas outside of the gas duct or such as ambient air, to be added to the main gas stream to attemperate the temperature of the main gas stream. The body or device may be referred to as a variable eductor having a plurality of openings through which a second gas may pass into the main gas stream. The openings may be opened or closed, and the variable eductor provides control over which openings and the degree to which each opening is opened. In some designs the variable eductor is inserted between two portions of a gas duct. The variable eductor has widespread application, such as downstream of a gas turbine to attemperate the exhaust gas temperature during startup.

Abstract

In general, the present invention is directed to methods for enhancing or improving the performance of a gas turbine. Generally, the present invention provides a method for adding additional air directly to a specific area within the compressor section of the gas turbine. In some embodiments, a separate or auxiliary air compressor can be used to provide a compressed air stream that is fed to certain points within the compressor section of the gas turbine in addition to the air normally being fed to the compressor inlet. By adding such additional air the total mass flow rate of air ultimately going to the combustion section of the gas turbine is increased, thereby providing for a corresponding increase in power output of the turbine section of the gas turbine.

Abstract

A method of eliminating dissimilar metal welds has been disclosed. The method includes the steps of providing a first part having a first alloy composition; providing a second part having a second alloy composition different from the first part; connecting a containment structure to the first part; pouring a powder into the containment structure such that the powder is in contact with the first part; positioning a portion of the second part in the containment structure such that the second part compresses the powder between the first and second parts; and performing hot isostatic pressing (HIP) to consolidate the powder and join the first and second parts together.

Abstract

The present invention provides a modification to the EBW process, which is referred to as a slope-out methodology, the results in the formation of a "slope-out portion" located generally in that region of the overall weldment located at the end of the ordinary EBW welding process for joining two components. The slope-out portion overlaps with the initial weld of the workpiece for a given distance or length along the weld and effectively eliminates the keyhole and provides a weldment that has minimal to no defects, particularly in the slope-out portion. The slope-out methodology begins by adjusting various parameters related to the electron beam to essentially decay the beam. In general, the focus position of the electron beam is moved from under-focused (focal position in the bulk of the material) to over-focused (focal position ahead of the workpiece surface) as the overlapping weld is made.

Abstract

A sensor-enabled aerial vehicle carries spatial electric and magnetic field detection sensors and a processing system that employs algorithmic methods to process sensor data. The sensors effectively detect electric and magnetic fields that emanate from energized objects, and the algorithmic methodology analyzes the sensor data to distinguish whether the energized object is unintentionally energized. The aerial propulsion system is enclosed within two electrically conducting hemispheres that are electrically insulated from each other. Alternatively, the hemispheres may be suspended below the aerial vehicle. The hemispheres function as a large area electric-field collection surface, wherein a small alternating current (AC) developed between the two hemispheres is proportional to the collected AC electric fields.
