摘要： A bullet for a rifle, an artillery shell, or even a missile is all subject to drag. The vacuum created as air moving at high speed passes over the end or past any change of angle of a projectile or missile slows the projectile or missile. Placing dimples or depressions, or the inverse thereof, around the circumference and or along the length of a bullet to create vortices to disrupt the air flow will fill the area where partial vacuums form with air. The streamlined boat tail bullet design, as an example, reduces this form drag by allowing the air to flow along the surface of the tapering end. The resulting aerodynamic advantage is currently seen as the optimum shape for rifle technology. This invention will also further reduce drag and increase range, velocity, and trajectory.
摘要翻译：用于步枪，炮弹，甚至导弹的子弹都会受阻。空气高速运转的真空越过了过去或过去，射弹或导弹的任何角度变化都会使射弹或导弹减速。在圆周上和/或沿着子弹的长度放置凹坑或凹陷或其倒数以产生涡流以破坏空气流将填充部分真空与空气形成的区域。作为示例，流线型的船尾弹丸设计通过允许空气沿着锥形端部的表面流动来减小这种形式的阻力。所产生的空气动力学优势目前被看作是步枪技术的最佳形状。本发明还将进一步减少阻力并增加范围，速度和轨迹。

摘要： Active superhydrophobic surface structures are actively-controlled surface structures exhibiting a superhydrophobic state and an ordinary state. Active superhydrophobic surface structures comprise an outer elastomeric covering defining an exposed surface, a controlled group of MEMS (micro-electro-mechanical system) actuators at least covered by the elastomeric covering, and, a controlled region of the exposed surface corresponding to the controlled group. The controlled region has a superhydrophobic state in which the controlled region is textured. The controlled region also has an ordinary state in which the controlled region is smooth (i.e., less textured than in the superhydrophobic state). Active superhydrophobic surface structures may be part of an apparatus that includes a controller and/or one or more sensors. The controller, sensors, and the controlled region may form a feedback loop in which the active superhydrophobic surface is actively controlled.

摘要： A viscous drag-reducing surface is provided that achieves harmony between an object and the environment (liquid or gas) through which the object moves. Rather than opposing the effects of friction, the surface according to the present invention eliminates friction by bonding the environment to the object. The pressure generated on the object by the environment as the object moves through the environment effectively compresses the local environment onto the surface. Once compressed against the surface, the local environment in contact with the surface becomes static relative to the surface whereas the environment that is not in contact with the surface achieves a laminar flow. Friction is thereby significantly reduced, since friction between like substances (i.e. the in-contact environment and the environment that is not in contact with the surface) is minimal.
摘要翻译：提供粘性减阻表面，其实现物体与物体移动通过的环境（液体或气体）之间的和谐。不是反对摩擦的影响，根据本发明的表面通过将环境粘合到物体来消除摩擦。物体通过环境移动时，由环境产生的压力有效地将局部环境压缩到表面上。一旦压在表面上，与表面接触的局部环境相对于表面变得静止，而不与表面接触的环境达到层流。摩擦因此显着降低，因为类物质之间的摩擦（即接触环境和与表面不接触的环境）是最小的。
