Abstract: Techniques are disclosed for performing dump collection on a computing system. One technique includes detecting an error event on the computing system. After detecting the error event, a subset of hardware registers associated with the error event are determined. One or more hardware units within the computing system to capture data from are determined from a set of rules that specify an association between the one or more hardware units and the subset of hardware registers associated with the error event. Data is captured from each of the one or more hardware units.

Abstract: A turbine engine blade has an attachment root, a platform outboard of the attachment root, and an airfoil extending from the platform. The airfoil has pressure and suction sides extending between leading and trailing edges. An internal cooling passageway network includes at least one inlet in the root and a plurality of outlets along the airfoil. The passageway network includes a leading spanwise cavity fed by a first trunk. A streamwise cavity is inboard of a tip of the airfoil. A spanwise feed cavity feeds the streamwise cavity absent down-pass. A second trunk feeds the spanwise feed cavity.

Abstract: A turbine airfoil includes a span wise extending cavity formed from a ceramic mold and a slot extending from the cooling air cavity to a trailing edge being formed by a refractory metal core. The refractory metal core facilitates the reduction in the size of the slot and also in the reduction in the size of pedestals which pass transversely through the slot to interconnect the pressure side to the suction side of the airfoil. The blade has a cutback feature to expose a back surface on the inner side of the suction side wall with dimples being formed on the back surface so as to enhance heat transfer characteristics thereof. Provision is made for fabricating the dimples by way of a photo etching process.

Abstract: A gas turbine engine blade has a relatively large fillet to improve the characteristics of the air flow thereover. The fillet has a thin wall which, together with an impingement rib, defines a fillet cavity therebetween, and cooling air is provided to flow through impingement holes in the impingement rib and impinge on the rear surface of the fillet. The impingement holes are elongated in cross sectional shape with their elongations being orient in a direction generally transverse to a radial direction.

Abstract: A gas turbine engine blade has a relatively large fillet to improve the characteristics of the air flow thereover. The fillet has a thin wall which partially defines a fillet cavity therebehind, and cooling air is provided to the fillet cavity and is then routed to the outer surface by way film cooling holes. Various design features are provided to enhance the effectiveness of the cooling air being provided to both the fillet cavity and other cavities within the blade.
