Abstract: A method of isolating a turbine shroud from propeller loads in an engine having an outer case with a mount defining a mount plane and an attachment location within the mount plane, the mount configured for attachment of the engine to an aircraft at the attachment location to transfer the propeller loads. The shaft of the engine is supported with a portion of the outer case extending from the mount and defining a load path for the propeller loads. The turbine support case is attached to extend free of the load path, by attaching the turbine support case to the outer case only through a connection along the plane, the connection defining a pivot point allowing a limited relative pivoting motion around the pivot point between the turbine support case and the mount. The turbine shroud is located by directly connecting it to the turbine support case.

Abstract: A turboprop engine including an annular outer case including a mount ring for attachment to an aircraft along a plane to transfer loads from a propeller and having an annular flange extending radially inwardly therefrom within the plane, an annular turbine support case received within the outer case and connected to the outer case only through a direct connection with the annular flange allowing a limited relative pivoting motion between the turbine support case and the mount ring, and a turbine section including a rotor closely surrounded by a shroud with an annular tip clearance being defined therebetween, the shroud being directly connected to and located by the turbine support case. A method of isolating a turbine shroud from propeller loads in a propeller engine is also disclosed.

Abstract: A gas turbine engine including a gas generator module and a reduction gearbox module. The gas generator module has an axis which extends longitudinally along a centreline of the gas generator module, and the reduction gearbox module has an axis which extending longitudinally along the centreline of the reduction gearbox and is offset from said generator axis. The reduction gearbox is driven by an intermediate shaft angled relative to the turbine output shaft.

Abstract: A convectively-cooled hydraulic fluid tank system comprises a hydraulic fluid tank and a fluid cooler incorporated into the hydraulic fluid tank. The fluid cooler includes a vortex chamber having a wall made of a heat conductive material. An inlet is provided to direct incoming pressurized hydraulic fluid tangentially onto the inner surface of the vortex chamber wall to create a swirled flow of hydraulic fluid against the inner surface of the wall. A cooling structure extends from an exterior surface of the vortex chamber wall to promote heat dissipation.

Abstract: A power plant and transmission arrangement for a helicopter wherein the helicopter engine is integrated to the helicopter transmission to form therewith a single unit rigidly mounted to the helicopter frame. By so integrating the engine to the helicopter transmission the center of gravity of the engine can be placed closer to the rotor mast of the helicopter, thereby enhancing the stability and the handling characteristics of the helicopter.

Abstract: A method of paring a document, marked up using a given markup language before use of the document by an application such as a web browser, the document comprising markup and data, by identifying markup which is not used by the application; and creating a pared document using the same markup language, comprising other portions of the markup other than the identified portion. By tailoring the document to the application, the time that is required to download the document can be reduced, which is useful for users who are using slow links such as a connection through a cellular phone, and where the users device has limited display capabilities, meaning that much of the document cannot be used by the users application.

Abstract: Using a server to provide access to a plurality of unrelated types of services, to a user communicating from a remote terminal to the server, by detecting a service access command sent from the user, the service access command comprising an indication of a service type, the service access command having a syntax which uses only alphanumeric characters, or "#" or "*" characters. Interpreting the command involves extracting the service type, to detect if the command further comprises one or more parameters relating to the service, extracting any such parameters and initiating the provision of the selected service. By having a server which understands commands in a form having a syntax using a limited set of characters, service access from telephones or terminals with smaller keyboards, becomes easier.
