    Abstract: PROBLEM TO BE SOLVED: To provide a mounting tool which heightens the rigidity of a rotor integrated with a blade (IBR) during the process that the air foil shape of a rotor blade for a gas turbine engine is in the final stage of machining. SOLUTION: A fixture 10 includes a rigid ring 12 surrounding the periphery of an IBR 14, and the ring 12 supports a taper pin 16 and is positioned in the space between blades 20. The space is formed by a casting process from a medium such as plaster or plastics in such a way that the ring is secured to the IBR, and thereby the structural integration is heightened. In the condition that the pins 16 are installed in every other inter-blade spaces, the blade surfaces confronting the spaces with no pin provided are subjected to machining process. Then a casting medium is melted and the pins are removed from the IBR, and in the condition that pins are installed in those spaces which are machined first, the blade surfaces confronting the spaces with pins removed are subjected to machining, followed by removal of pins again.

    Abstract: A fan blade includes first and second titanium portions that are secured to one another with an aluminum alloy braze. A method of manufacturing a fan blade includes providing first and second titanium portions, applying an aluminum alloy braze to at least one of the first and second titanium portions, and heating the fan blade to melt the aluminum alloy braze and join the first and second portions to one another to provide a fan blade with an airfoil exterior contour.

    Abstract: A fixture for use in the final machining operation of the integral bladed rotor (IBR) of a gas turbine engine comprises a rigid ring (12) for surrounding the outer periphery of the IBR (14) and supporting tapered pins (16) that fit into the space between the blades (20) and then molded therein with a plaster or plastic medium for securing the unit to the IBR for enhancing its structural integrity. The method of finishing the airfoils of the IBR includes inserting the pins in alternate spaces and working half of the blade surfaces in the pinless spaces and then removing the pins and inserting pins in the previously worked spaces and then molding the pins in place. The other half of the bladed surface is then worked in the pinless spaces until the airfoils are finally contoured. The unit is removed and heated to melt the residual cast medium to produce the finished product.

    Abstract: Cooling tubes (2) are positioned within a structural jacket (10) to form a tube bundle (25), and a liner (30) is positioned within the tube bundle thereby sandwiching the tubes between the jacket and the liner. The tubes are then subjected to high internal pressure and inflated while the liner is simultaneously subjected to the same high pressure, thereby forcing the tubes into intimate contact with adjacent tubes, the liner and the jacket. The tubes, liner and jacket are then subjected to ultrasonic vibrations to bond the tubes and jacket into an integral structure.
