The invention focuses on how to carry out quieter supersonic flight. Various technologies and methods are developed and specially used for solving the noise problem of supersonic flight. Noise of supersonic flight is propagated from the aircraft to the ground, so that the noise can be effectively prevented from being propagated to the ground by adding an interference medium (202) between the aircraft and the ground. The noise level can also be reduced using specially designed aircraft wings. The specially designed wing portion is inspired from the flight of a bird flock. The actively-emitted impact airflow is used for blowing away the airflow at the front edge of the windward side of the aircraft, or the airflow at the bottom of the aircraft body is guided away through a small hole (901) formed in the bottom of the aircraft body, and noise spread from the aircraft to the ground can also be reduced.

    本专利专注于如何进行更为安静的超音速飞行。有多种技术和方法被研制出来专门用于解决超音速飞行的噪音问题。超音速飞行的噪音是从飞机传播到地面的,所以在两者之间增加干涉媒介(202)可以有效地阻止噪音向地面传播。使用特别设计的飞机机翼同样可以减少噪音水平。这种特别设计的机翼部分灵感是源自鸟群的飞行。使用主动发射的冲击气流把飞机迎风面的前缘的气流吹开,或者利用在飞机机身底部设置的小洞(901)把机身底部的气流导走同样可以减少从飞机传播到地面的噪音。
