Abstract
A core compartment ventilation device is provided. The core compartment ventilation device comprises a fireproof sealing member for substantially sealing a core compartment in a nacelle for a gas turbine engine and a chimney configured to be in fluid communication with the fireproof sealing member for conducting hot air from the core compartment to the external atmosphere via the fireproof sealing member. A gas turbine engine and nacelle including the core compartment ventilation device are also provided.
Claims20
A core compartment ventilation device comprising:
- a fireproof sealing member for substantially sealing a core compartment in a nacelle for a gas turbine engine;
- and
- a chimney in fluid communication with the fireproof sealing member and extending radially outward from the fireproof sealing member to discharge hot air from the core compartment to an atmosphere external to the nacelle.
A gas turbine engine comprising:
- a fan duct including a fan duct inner structure that surrounds a core engine and encloses a core compartment;
- a pylon structure coupled to the core engine;
- and
- a core compartment ventilation device for sealing the core compartment against fire and for ventilating hot air from the core compartment to an external atmosphere, the core compartment ventilation device comprising:
- a fireproof sealing member;
- and
- a chimney in fluid communication with the fireproof sealing member, wherein the chimney extends radially outward from the fireproof sealing member and is located between the fan duct inner structure and the pylon structure.
A nacelle for a gas turbine engine connected to a pylon structure, the nacelle comprising:
- an upper bifurcation;
- a lower bifurcation;
- a fan duct inner structure extending between the upper bifurcation and the lower bifurcation, wherein the upper bifurcation, the lower bifurcation, and the fan duct inner structure define, at least partially, a core compartment located between an engine core of the gas turbine engine and the upper bifurcation, the lower bifurcation, and the fan duct inner structure;
- and
- a core compartment ventilation device in fluid communication with the core compartment, the core compartment ventilation device comprising:
- a fireproof sealing member;
- and
- a chimney in fluid communication with the fireproof sealing member and extending radially outward from the fireproof sealing member.
