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.
Claims20
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 one fuel channel defined through the tube body between said inlet and said outlet, the outlet of the fuel channel being in fluid communication with the manifold;
- and
- at least a portion of the tube body being offset from said plane.
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 channel providing fluid flow communication between first and second ends of the tube body, the channel defining a channel axis extending between said first and second ends, at least a portion of the channel axis defining a tube body plane which is spaced apart from the manifold plane.
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 means for providing fluid flow communication between first and second ends of the tube body, and means for offsetting at least a portion of the tube body from the manifold 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;
- and
- an inlet tube having a tube body extending between an inlet and an outlet, the outlet being engaged with the internal fuel manifold ring 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.
