Abstract
A gas turbine engine including a turbomachine. The turbomachine including a compressor section, a combustion section, and a turbine section arranged in serial flow order. The turbomachine including an inlet duct defining an engine inlet, a fan duct defining a fan duct inlet, and a core duct defining a core duct inlet. The gas turbine engine including a fan cowl disposed circumferentially around the turbomachine and a heat exchanger defining a portion of the fan duct. At least a portion of the heat exchanger formed integrally with or coupled to the fan cowl.
Claims20
A gas turbine engine comprising:
- a turbomachine comprising a compressor section, a combustion section, and a turbine section arranged in serial flow order, the turbomachine including an inlet duct defining an engine inlet, a fan duct defining a fan duct inlet, and a core duct defining a core inlet;
- a fan cowl disposed circumferentially around the turbomachine;
- and
- a heat exchanger defining a portion of the fan duct, at least a portion of the heat exchanger formed integrally with or coupled to the fan cowl,
- wherein the heat exchanger comprises an inlet, a main body, and an outlet, and wherein the inlet and the outlet are formed integrally with or coupled to the fan cowl.
A gas turbine engine comprising:
- a turbomachine comprising a compressor section, a combustion section, and a turbine section arranged in serial flow order, the turbomachine including an inlet duct defining an engine inlet, a fan duct defining a fan duct inlet, and a core duct defining a core inlet;
- a primary fan driven by the turbomachine;
- a secondary fan located downstream of the primary fan within the inlet duct;
- and
- a heat exchanger located in an aft 50% of the fan duct,
- wherein the fan duct comprises a forward portion and an aft portion, and wherein the heat exchanger forms the aft portion of the fan duct.
