Abstract: Braze brackets utilized in connection with securing tubes and ducts to turbine engines are described. In one embodiment, the bracket includes a mounting plate having a curved braze surface. A plurality of tangs extend from the mounting plate. The specific dimensions for the braze surface and the tangs are selected depending upon the duct or tube to which the bracket is to be secured and the main bracket body to be used in connection with the bracket. In one embodiment, the curved braze surface has a semi-cylindrical geometric shape, and the tangs extend substantially radially from edges of the braze surface. The tangs are spaced along the edges of the braze surface.

Abstract: A design system for designing a tube for a gas turbine engine is described. The system including, in one embodiment, a computer workstation having a plurality of executable modules stored therein. The modules include a tube design module for routing a tube between tube fittings, a tube editing module for editing tube assembly geometry, and a tube detailing module for preparing detail drawings.

Abstract: A design system for designing brackets for gas turbine engines is described. The system may be implemented with a computer workstation and includes a part model library and a drawing note library. The computer workstation is configured to receive a bracket model in electronic form as input and has a number of executable modules stored therein. The system outputs a bracket master model and detail drawings. In one embodiment, the modules include a bracket intelligence builder module for generating intelligence data for the bracket model, a bracket unfolding module for unfolding a bracket model to a flat pattern, a bracket folding module to fold a bracket flat pattern, and a bracket minimum material check module to check for minimum distances between bracket pattern features. Other modules also are described and may form a elements of the system.

Abstract: A tubular wear sleeve includes radially outer and inner surfaces, with the inner surface having at least one protuberance extending radially inwardly therefrom for being received in a complementary indentation in a fluid carrying tube for restraining relative movement therebetween.

Abstract: An adjustable loop clamp assembly provides improved retention of electrical cables, tubes or hoses. The clamp assembly comprises a flexible strap with first and second ends. A base, having an elevated platform, a lower platform, a midsection, and two side supports, receives a second end of the strap in an aperture of the midsection. The first strap end is securably affixed to the elevated platform of the base. Support holes in the side supports receive pin portions of a locking cam, the locking cam further comprising a handle portion and a cam portion. A mount bolt is receivable in alignable apertures of the lower platform and the handle portion.

Abstract: A coupling assembly for fluid carrying tubes in a gas turbine engine include first and second fittings fixedly joined to respective ones of the tubes. The first and second fittings include respective first and second mating flanges which are joined together by a clamping band which is adjustable therearound. The first and second flanges include oppositely facing first and second flat faces, with the first flange having a counterbore extending inwardly from the first face, and the second flange having a pilot tube extending outwardly therefrom for being inserted into the counterbore. An annular seal is disposed between the first and second fittings for providing a leak-proof coupling upon clamping together of the two fittings by the clamping band.

Abstract: An expansion joint for connecting first and second fluid-carrying pipes comprising first and second annular couplings which are operably affixable to respective ones of the pipes. In a preferred embodiment the couplings include cylindrical bores of substantially the same diameter disposed relative to one another to form a passage for providing flow communication between the pipes. An annular bellows extends between the couplings for accommodating relative axial movement and angular misalignment between the pipes and is disposed radially outward of the passage to capture any fluid leaking between the interfacing surfaces of the couplings. A second cylindrical bore of a first one of the couplings engages an outer spherical surface of the second coupling to allow the second coupling to pivot in a manner which accommodates angular misalignment between the pipes.
