Abstract
A turbofan engine includes an outer bypass duct and a gas turbine engine having an outer casing. The gas turbine engine is disposed in the outer bypass duct such that a bypass airflow passage is formed between the outer casing of the gas turbine engine and the outer bypass duct. The turbofan engine includes a turbine rear frame link assembly including a set of links coupled between the outer bypass duct and the outer casing to support the gas turbine engine relative to the outer bypass duct. The links are arranged around the gas turbine engine on a plane that is perpendicular to a centerline axis of the turbofan engine. None of the links extends through the bypass airflow passage at a position that intersects a radius extending in a vertically downward direction from the centerline axis.
