Abstract: A method and apparatus for internally mounting a fuel manifold within a surrounding casing in a gas turbine engine which involves inserting the fuel manifold into the casing with support elements positioned in a retracted position, displacing the support elements into an extended position, and fastening said support elements to mount the manifold to an inner surface of said casing.

Abstract: A method and device for improved pressure balancing in a bearing chamber pressurization system for gas turbine engines employ a partition member to substantially separate first and second air-oil seals of the bearing housing.

Abstract: A gas turbine diffuser assembly and a method for assembling same, includes providing a loose fit between the diffuser body and the diffuser pipes. Damper members provide a snug attachment.

Abstract: The present invention includes a rotor assembly comprising a shaft, a first component coaxially attached to the shaft for performing a first function in the rotor assembly and acting as a first counterbalance weight, and a second component coaxially attached to the shaft for performing a second function in the rotor assembly and acting as a second counterbalance weight, whereby the first and second counterbalance weights combine to balance the rotor assembly. The present invention also includes a method of balancing a rotor assembly having a shaft and a residual imbalance, the method comprising the steps of coaxially attaching a first component performing a first function and having a first counterbalance weight integral therewith onto the shaft, and coaxially attaching a second component performing a second function and having a second counterbalance weight integral therewith onto the shaft, so that the first and second components counter the residual imbalance.

Abstract: In a gas turbine engine, a fuel inlet tube comprising a body, a channel defined in the body and in fluid communication with a manifold, and a side inlet in fluid communication with the channel, such that fuel entering the side inlet is delivered to the manifold through the channel with a pressure generally directed along a radial axis of the body. Also, a fuel inlet tube comprising a heat shield surrounding at least part of a body, a chamber defined between the heat shield and the body and in fluid communication with fuel leak sources, a drain channel defined in the body in fluid communication with the chamber, and a drain hole defined in the body in fluid communication with the drain channel, such that a leak produces fuel received in the chamber and safely directed through the channel and the hole to allow detection of the leak.
