    摘要： The present invention blocks and/or attenuates the upstream travel of acoustic disturbances or sound waves from a flight vehicle or components of a flight vehicle traveling at subsonic speed using a local injection of a high molecular weight gas. Additional benefit may also be obtained by lowering the temperature of the gas. Preferably, the invention has a means of distributing the high molecular weight gas from the nose, wing, component, or other structure of the flight vehicle into the upstream or surrounding air flow. Two techniques for distribution are direct gas injection and sublimation of the high molecular weight solid material from the vehicle surface. The high molecular weight and low temperature of the gas significantly decreases the local speed of sound such that a localized region of supersonic flow and possibly shock waves are formed, preventing the upstream travel of sound waves from the flight vehicle.

    摘要翻译： 本发明使用高分子量气体的局部注入来阻止和/或衰减来自飞行车辆或以亚音速行驶的飞行车辆的部件的声学干扰或声波的上行行程。 还可以通过降低气体的温度来获得额外的益处。 优选地，本发明具有将高分子量气体从飞行器的鼻子，翼，部件或其他结构分配到上游或周围空气流中的手段。 用于分配的两种技术是从车辆表面直接喷射和升华高分子量固体材料。 气体的高分子量和低温显着地降低了本地的声速，从而形成了超音速流动和可能的冲击波的局部区域，从而防止来自飞行器的声波的上游行进。
