Apparatuses and systems are provided herein for non-ducted propulsion systems. The system includes an efficient front housing for high subsonic continuous flight. The plurality of blades are secured to the front housing, wherein the front housing defines a flow path curve extending from a front-most end of the front housing through an axial extent of a front blade root. The flow path curve is described by an axial direction parallel to the axis of rotation and a radius from the axis of rotation. The flow path curve includes a first point having a first radius where the radius reaches a maximum forward of the leading blade root and a second point rearward of the first point, the second point having a second radius where the radius stops decreasing. The ratio of the first radius to the second radius is greater than or equal to 1.029.

    本文为非管道式推进系统提供了设备和系统。该系统包括用于高亚音速持续飞行的高效前壳体。多个叶片固定到前壳体,其中前壳体限定从前壳体的最前端延伸通过前叶片根部的轴向范围的流动路径曲线。流动路径曲线由平行于旋转轴线的轴向方向和距旋转轴线的半径来描述。流动路径曲线包括第一点和第一点后方的第二点,第一点具有第一半径,其中半径在前叶片根部的前方达到最大值,第二点具有第二半径,其中半径停止减小。第一半径与第二半径的比大于或等于1.029。
