    Abstract: A ring segment system (100) for a gas turbine engine (10) is disclosed. The ring segment system (100) may be formed from ring segments (50) that circumferentially surround a rotor assembly (40). The ring segments (50) may each include a carrier portion (34) that is coupled to a vane carrier (28), and a heat shielding portion (38) that is detachably coupled to the carrier portion (34). The detachable coupling may allow the heat shielding portion (38) to be uncoupled from the carrier portion (34) and removed from the gas turbine engine (10) axially. The ring segments (50) may further include cooling fluid supply channels (72) that allow cooling fluid to flow from a radially outward facing backside (42) of the ring segments (50) to a radially inward facing front side (46). Additionally, the ring segments (50) may also include ingestion prevention channels (76) that allow cooling fluid to create a barrier over the gap (80) between the ring segments (50) and the adjacent vane (18).

  • Publication number: 20170218729
    Abstract: The feasibility of performing hydraulic fracturing can be assessed by analyzing the effect of skin on the overall deliverability of a reservoir. Aspects of the disclosure provide a method to determine equivalent skin in hydraulic fractured system through a semi analytical correlation obtained by numerical modeling. Two 3D models are considered: a base case without fracture and a complex case with fractures. The base case is simulated by varying matrix permeabilities while the fractured model is run with different sets of varying fracture's lengths, widths, and permeability as well as matrix permeabilities. The two cases are comparatively analyzed and skin is determined. A generalized correlation for determination of skin is derived through application of multivariate regression technique on obtained skins and their corresponding variables.

  • Patent number: 9629055
    Abstract: A system and method for protection against loss of communication of a mobile node crossing a black spot region is disclosed. The system to prevent loss of communication with the mobile node consists of a mobile node, RF coverage map generator, black spot predictor, and a vertical handover process. The mobile node can experience uninterrupted communication across black spots. This is achieved by executing vertical handover before entering a black spot region, which is anticipated by using RF coverage maps and mobility pattern of the mobile node.
