Abstract: The present invention provides a method of designing a manufacturing geometry for a tip portion of a rotary blade for a gas turbine engine. The method comprises first devising a theoretical hot running geometry of the tip portion at a specified design condition. Next, the theoretical operational forces acting on the theoretical hot running geometry at the specified design condition are calculated e.g. using CFD software. Then, the manufacturing geometry is determined (e.g. using FEA analysis) using the calculated theoretical operational forces.

Abstract: Disclosed embodiments relate to the graphical display of relationships between entities of interest, and specifically between entities in a network of relationships. In such embodiments, multiple icons on an axis between two entities are used to indicate that the entities have multiple relationships. Disclosed embodiments also provide methods of navigating, filtering, and manipulating the display of networked relationships, according to the numerical distribution of relationships and specific combinations of relationships. Disclosed embodiments provide methods of manipulating the display of networked relationships so that relationships between entities can be visually collapsed, and entities can be treated as links between other entities for the purposes of filtering and display.

Abstract: A casing section (30) for rotary apparatus (13, 14) of a gas turbine engine (10) is described. The casing section (30) comprises a partially circumferential casing member (32) and a plurality of radially inwardly extending vanes (34) fixed on the casing member (32).

Abstract: A dolly device for facilitating moving of an object by a user. The dolly device includes a base member being designed for supporting the object when the object is placed on the base member. A pair of side members are oppositely coupled to the base member. Each of the side members is positioned substantially orthogonally to the base member. The side members are designed for engaging the object for inhibiting the object from tipping off of the base member when the object is positioned on the base member. At least one wheel is rotatably coupled to each of the side members. The wheel is designed for rollably engaging a support surface for facilitating movement of the object across the support surface when the object is positioned on the base member and the base member is moved across the support surface by the user.
