Abstract: A flow-management system may comprise a center body impermeable to air. A conical surface of the center body may face forward. A blocking surface of the center body may be coaxial with the conical surface and may comprise an annular recess. An annular ring may be aft of the center body and fluidly coupled with the blocking surface. A tube may encase the center body and annular ring. The annular ring may comprise an air-foil shape to direct a pulse to the blocking surface. The blocking surface may comprise a central peak and a circular ridge separated by the annular recess.
Abstract translation: 流量管理系统可以包括不透气的中心体。 中心体的锥形表面可能面向前方。 中心体的阻挡表面可以与锥形表面同轴并且可以包括环形凹部。 环形环可以是中心体的后部并且与阻挡表面流体连接。 管可以包住中心体和环形环。 环形环可以包括将箔脉冲引导到阻挡表面的空气箔形状。 阻挡表面可以包括由环形凹部分开的中心峰和圆形脊。

Abstract: An inlet manifold for a multi-tube pulse detonation engine includes a vaneless diffuser disposed in a first zone to collect an air discharged from a compressor; a vaned diffuser including a plurality of guide vanes disposed in a second zone to slow the air from the compressor; a plenum disposed in a third zone located next to second zone to provide the air from the compressor to chambers; and a splitter disposed in a fourth zone to split the air from the compressor into an airflow required by each pulse detonation tube for detonation.
Abstract translation: 用于多管脉冲爆震发动机的入口歧管包括设置在第一区域中的无叶漫射器，以收集从压缩机排出的空气; 一种叶片式扩散器，包括设置在第二区域中的多个导向叶片，以减缓来自压缩机的空气; 设置在靠近第二区域的第三区域中的气室，以将空气从压缩机提供到腔室; 以及设置在第四区域中以将来自压缩机的空气分成每个脉冲爆管所需的气流用于爆炸的分流器。

Abstract: The engine (10) includes at least one firing tube (12) wherein an exhaust stream (32) from the firing tube (12) drives a turbine (30). A scroll ejector attenuator (40) is secured between and in fluid communication with an outlet end (28) of the firing tube (12) and an inlet (76) of the turbine (30). The attenuator (40) defines a turning, narrowing passageway (72) that extends a distance the exhaust stream (32) travels before entering the turbine (30) to attenuate shockwaves and mix the pulsed exhaust stream (32) into an even stream with minimal temperature differences to thereby enhance efficient operation of the turbine (30) without any significant pressure decline of exhaust stream (32) pressure and without any backpressure from the attenuator (40) on the firing tube (12).
Abstract translation: 发动机（10）包括至少一个燃烧管（12），其中来自燃烧管（12）的排气流（32）驱动涡轮机（30）。 涡卷喷射器衰减器（40）固定在燃烧管（12）的出口端（28）和与涡轮机（30）的入口（76）流体连通之间。 衰减器（40）限定了在进入涡轮机（30）之前延伸排气流（32）移动一段距离的转动，变窄的通道（72），以便衰减冲击波并将脉冲排气流（32）混合成均匀的流 从而增强了涡轮机（30）的有效运行，而没有任何明显的排气流（32）的压力下降并且没有来自激发管（12）上的衰减器（40）的任何背压。
