GEARED ARCHITECTURE FOR GAS TURBINE ENGINE

A turbofan engine includes a fan section. A turbine section is in driving engagement with the fan section through a geared architecture (48A). A flexible support (96A) supports the geared architecture (48A) relative to an engine static structure (36). A deflection limiter (150A) includes at least one of an axially extending branch or a radially extending branch. A flexible output shaft (120) is in driving engagement with the fan section and driven by the geared architecture (48A). A speed change mechanism for a gas turbine engine is also disclosed.
