    • A supersonic compressor including a rotor to deliver a gas at supersonic conditions to a diffuser. The diffuser includes a plurality of aerodynamic ducts that have converging and diverging portions, for deceleration of gas to subsonic conditions and then for expansion of subsonic gas, to change kinetic energy of the gas to static pressure. The aerodynamic ducts include structures for changing the effective contraction ratio to enable starting even when the aerodynamic ducts are designed for high pressure ratios, and structures for boundary layer control. In an embodiment, aerodynamic ducts are provided having an aspect ratio of in excess of two to one, when viewed in cross-section orthogonal to flow direction at an entrance to the aerodynamic duct. In an embodiment, the number of leading edges are minimized, and may be less than half, compared to the number of blades in the accompanying rotor.
    • 一种超音速压缩机,其包括用于在超音速条件下将气体输送到扩散器的转子。 扩散器包括具有会聚和发散部分的多个空气动力学管道,用于将气体减速到亚音速条件,然后用于膨胀亚音速气体,以将气体的动能改变为静态压力。 空气动力学管道包括用于改变有效收缩比的结构,使得即使当空气动力学管道被设计用于高压比时也能够启动,并且用于边界层控制的结构。 在一个实施例中,当在与空气动力学管道的入口处垂直于流动方向的横截面中观察时,提供具有超过2比1的纵横比的空气动力学管道。 在一个实施例中,前缘的数量最小化,并且可以小于伴随转子中的叶片数量的一半。
