Abstract
An inlet tube supplies fuel to a manifold of a combustor in a gas turbine engine, the manifold defining a manifold plane. The inlet tube comprises a tube body having a channel providing fluid flow communication between first and second ends of the tube body. At least a portion of the channel defines a tube body plane which is spaced apart from the manifold plane.
Claims13
An inlet tube for supplying fuel to a fuel manifold in a gas turbine engine, the fuel manifold lying in a plane substantially perpendicular to a central axis of the fuel manifold, the inlet tube comprising:
- a tube body defining a central axis extending between an inlet of the tube body and an outlet of the tube body;
- at least a first and a second fuel channel defined through the tube body between said inlet and said outlet, the first and second fuel channels being located side by side within the tube body, outlets of the first and second fuel channels being in fluid communication with the manifold;
- and
- at least a portion of the tube body being offset from said plane of the fuel manifold.
An inlet tube for supplying fuel to a manifold of a combustor in a gas turbine engine, the manifold defining a manifold plane, the inlet tube comprising:
- a tube body having a first and a second channel therein providing fluid flow communication between first and second ends of the tube body, the first and second channels respectively defining a first and a second channel axis extending between said first and second ends, at least a portion of the channel axis defining a tube body plane distinct from the manifold plane, the first and second channel axes being offset from one another and extending at least partially within the tube plane.
A fuel manifold assembly for a combustor in a gas turbine engine, the fuel manifold assembly comprising:
- an internal fuel manifold ring having at least one fuel flow passage, the internal fuel manifold ring defining a manifold plane substantially perpendicular to a central manifold axis;
- the ring having a radially-outer periphery;
- and
- an inlet tube having a tube body defining at least first and second fuel channels therein extending side by side between an inlet and an outlet of the tube body, the outlet being engaged with the internal fuel manifold ring at the radially-outer periphery and being in fluid flow communication with said fuel flow passage, at least a portion of the tube body defining a tube body plane which is spaced apart from the manifold plane and within which the first and second fuel channels lie.
