GAS TURBINE ENGINE WITH THIRD STREAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240318613 titled 'GAS TURBINE ENGINE WITH THIRD STREAM

The gas turbine engine described in the abstract includes a primary fan, a secondary fan, and specific airflow ratios.

• The gas turbine engine has a thrust to power airflow ratio between 3.5 and 100.
• The engine also has a core bypass ratio between 0.1 and 10.
• The thrust to power airflow ratio is the ratio of airflow through the bypass passage and the fan duct to the airflow through the core duct.
• The core bypass ratio is the ratio of airflow through the fan duct to the airflow through the core duct.

Original Abstract Submitted

a gas turbine engine is provided. the gas turbine engine includes a turbomachine defining an engine inlet to an inlet duct, a fan duct inlet to a fan duct, and a core inlet to a core duct; a primary fan driven by the turbomachine; and a secondary fan located downstream of the primary fan within the inlet duct. the gas turbine engine defines a thrust to power airflow ratio between 3.5 and 100 and a core bypass ratio between 0.1 and 10, wherein the thrust to power airflow ratio is a ratio of an airflow through a bypass passage over the turbomachine plus an airflow through the fan duct to an airflow through the core duct, and wherein the core bypass ratio is a ratio of the airflow through the fan duct to the airflow through the core duct.
