摘要： The present invention relates to a bullet including an air-guiding recess, comprising: a head 20; and a tail 30 disposed behind the head 20, and including an odd number of air-guiding recesses 32 formed so as to be curved in the bottom and outer circumferential surfaces thereof. The air-guiding recess 32 is characterized by having a sloped bottom that increases in depth while progressing to the bottom surface of the tail 30. Accordingly, vortex is prevented from being generated at the rear side of the bullet, so as to significantly increase the effective range thereof and simultaneously improve accuracy when shooting same.
摘要翻译：本发明涉及一种包括空气引导凹部的子弹，包括：头部20; 以及设置在头部20后面的尾部30，并且包括形成为在其底部和外周表面上弯曲的奇数个空气引导凹部32。空气引导凹部32的特征在于具有倾斜的底部，其在进入尾部30的底表面的同时增加深度。因此，防止在子弹的后侧产生涡流，从而显着增加有效范围，同时提高拍摄时的精度。

摘要： A method for enhancing an aerodynamic performance of an unmanned projectile. The method including at least one of the following: (a) morphing a cross-sectional shape of the projectile after launch thereof; (b) morphing a longitudinal shape of the projectile after launch thereof; (c) bleeding a fluid at a base of the projectile during flight thereof: (d) varying a base cone angle of the projectile as a function of speed thereof; (e) deploying at least one wing from a body of the projectile after launch thereof; and (f) deploying a fin from the body of the projectile after launch thereof.
