    • An exemplary gas turbine engine includes a fan, a compressor section, a combustor in fluid communication with the compressor section and a turbine section in fluid communication with the combustor. The fan includes a first plurality of fan blades supported on a first fan support and a second plurality of fan blades supported on a second fan support. The first and second fan supports are rotatable about a fan axis independently of each other. A geared architecture includes at least one gear driven by the turbine section for rotating about a gear axis that is transverse to the fan axis. The gear drives the fan supports for rotating the respective pluralities of fan blades in opposite directions.
    • 示例性的燃气涡轮发动机包括风扇,压缩机部分,与压缩机部分流体连通的燃烧器以及与燃烧器流体连通的涡轮部分。 风扇包括支撑在第一风扇支撑件上的第一多个风扇叶片和支撑在第二风扇支撑件上的第二多个风扇叶片。 第一和第二风扇支撑件可以彼此独立地围绕风扇轴线旋转。 齿轮架构包括由涡轮部分驱动的至少一个齿轮,用于围绕横向于风扇轴线的齿轮轴线旋转。 该齿轮驱动风扇支撑件,用于以相反的方向旋转相应的多个风扇叶片。
