Abstract

A gas turbine engine includes an engine static structure housing that includes a compressor section and a turbine section. A core nacelle encloses the engine static structure to provide a core compartment. An oil tank is arranged in the core compartment and is axially aligned with the compressor section. Fan and core nacelles define an annular bypass flow path. The core nacelle provides a core compartment and includes an opening into the core compartment. The oil tank is arranged in the core compartment and includes a portion aligned with the opening that is exposed to the bypass flow path. The engine static structure is supported relative to a fan case by a radial structure. The oil tank is mounted to the engine static structure. An oil fill tube is mounted to the fan case and is fluidly connected to the oil tank.

Claims (8)

1. A gas turbine engine comprising:

an engine static structure housing a compressor section and a turbine section, and a combustor section arranged axially between the compressor section and the turbine section;

a core nacelle enclosing the engine static structure to provide a core compartment; and

an oil tank arranged in the core compartment and axially aligned with the compressor section, wherein the oil tank includes a wall having fins extending through slots in the core nacelle into a bypass flow path.

2. A gas turbine engine comprising:

fan and core nacelles defining an annular bypass flow path, the core nacelle providing a core compartment and including an opening into the core compartment; and

an oil tank arranged in the core compartment and including a portion aligned with the opening and exposed to the annular bypass flow path, wherein the oil tank includes a wall having fins extending through slots providing the opening and into the annular bypass flow path.

3. The engine according to claim 2 , wherein the oil tank includes an exterior surface arranged in the opening, the core nacelle having an outer contour facing the annular bypass flow path, and the exterior surface following the outer contour.
