飞片下的空气形成的“超强高速气流刀”

The "Hypervelocity Airflow Knife" Formed by Air underneath the Flyer

文章描述了一次超乎异常的实验现象:飞片在四周完全临空的空间中高速向下飞行时,飞片下方常压下的空气很难从四周排出,最终在飞片与靶板间隙内受到绝热压缩,产生"超强高速气流刀"。文章详述了实验的过程与现象,并用气体绝热压缩的理论导出了受绝热压缩的气体压力与质点速度值,从而建立了产生"超高速气流刀"的理论。

An unusual experimental phenomenon has been discribed in this article：when the flyer plunges down at a very high speed in a completely opening space,the air of atmospheric pressure underneath the flyer is hard to be discharged and ultimately the ＂ Hypervelocity Airflow Knife＂ has been formed between the gaps of the flyers and target plates by adiabatic compression.The process and phenomenon of the experiment has been recorded in detail.Gas pressure and particle velocity value under adiabatic compression has been calculated through the gas adiabatic compression theory,hence the theory of ＂Hypervelocity Airflow Knife＂ has been established.
