Abstract:
The present application thus provides a turbine bucket. The turbine bucket may include a platform, an airfoil extending from the platform at an intersection thereof, and a core cavity extending within the platform and the airfoil. The core cavity may include a contoured turn about the intersection so as to reduce thermal stress therein.
Abstract:
A filter cartridge protective sleeve is provided. The filter cartridge protective sleeve includes a cylindrical body formed of a non-rigid, flexible and resilient silicone material configured to be frictionally retained to a filter cartridge by expanding said body to conform to at least a portion of the filter cartridge. At least one flow opening is formed through the sleeve to permit a flow of water/liquid to the filter cartridge. The sleeve may include indicia elevated from an exterior surface of the body. The indicia and body are integral and formed of the same material.
Abstract:
Blades of increased blade angle may be retrofitted onto existing compressor rotor wheels as replacement blades whereby higher performance and efficiency without replacing the rotor wheel may be achieved. The base attachments of replacement blades are provided with lateral extensions or flanges and the rim of the compressor wheel is provided with recesses straddling the grooves to accommodate the flanges. The leading edge of the replacement blade is positioned circumferentially for support only by the platform extension thereby limiting the mean and vibratory stresses in the leading edge of the airfoil and maximizing damage tolerance.
Abstract:
The present application provides an inner nozzle platform. The inner nozzle platform may include a platform cavity, an impingement plenum positioned within the platform cavity, a retention plate positioned on a first side of the impingement plenum, and a compliant seal positioned on a second side of the impingement plenum.
Abstract:
Entities seeking to promote goods, services, offers, candidates, etc., may elect to use advocates in a social networking environments instead of advertising. Social networking user profile characteristics are analyzed to identify advocates for subjects of advocacy such as brands, products, services, offers, political candidates, etc. Profile characteristics may include the advocate's own profile information as well as profile information of those in the advocate's social network. An advocate may select a subject of advocacy and generate advocacy materials or customized advocacy materials may be created and/or combined with user materials. The advocacy materials may be analyzed using neuro-response data to generate effective and targeted materials for distribution using social networking channels.
Abstract:
Users in a social networking environment are matched with subjects of advocacy, such as products, services, offers, candidates, etc., by evaluating user profile characteristic information. The user may provide advocacy materials and an advocacy system may also generate advocacy materials that may be incorporated with the user's own testimonials. The advocacy materials are distributed using social network channels. A remuneration tracking system monitors distribution of the advocacy materials and analyzes metrics to determine the effectiveness of the distribution. In some examples, the renumeration tracking system monitors redistribution of the advocacy materials, purchase or selection of an offer upon viewing the advocacy materials, and/or commenting or positively valuing the advocacy materials.
Abstract:
A method for assembling a stator assembly for a turbine engine is provided. The method includes providing a blade with a base including an end wall having at least one hole defined therein and providing a shim having at least one aperture extending therethrough. The shim aperture is aligned with the end wall hole, and the shim is secured to the blade base end wall using a fastener. The fastener is inserted through the shim aperture in an interference fit within the end wall hole. The blade and the shim are coupled to a turbine casing.
Abstract:
A method of tuning a compressor stator blade having a base portion and an airfoil portion to achieve a desired natural frequency, includes a) identifying the natural frequency of the compressor stator blade; b) determining a different target natural frequency for the compressor stator blade; and c) removing material from the base portion of the compressor stator blade in an amount and in a configuration that achieves the target natural frequency. A frequency-tuned compressor stator blade includes an airfoil portion and a base portion, the base portion having a substantially solid rectangular shape; and a groove cut across a width dimension of the base portion, the groove having dimensions selected to obtain a predetermined natural frequency for the airfoil portion.
