A warhead casing includes a nose region, a tail region, a tubular body region, and a central cavity extending along a lengthwise axis and having a first axial end and a second axial end. An aft wall is formed integrally with the tail region and extends radially toward the lengthwise axis to define the second end of the central cavity, and includes an aperture configured to receive a fuse device. A method of manufacturing a warhead casing includes forming a nose portion, a body portion, and a tail portion. The tail portion includes a circumferential outer wall defining an inner cavity, and an aft wall integrally formed with the circumferential outer wall and extending radially inward to define an axial end of the inner cavity. At least one of the nose portion or the tail portion is joined to the body portion.

A projectile and a projectile mount having a central bore into which the projectile is mounted and includes rotational formations functionally engaging between the projectile and the projectile mount which in use provides rotational motion to the projectile around an axis of rotation by the propulsion of the projectile along the axis of rotation.

A round of ammunition including projectiles formed in a stack and having an offset center of mass. Upon discharge, the projectiles are subject to a complex flight path and increased drag, providing advantages in controlling pattern and depth of penetration at a distance.

The archery arrow having improved flight characteristics of the present invention is designed to improve the accuracy of the arrow which is equipped with a dampening medium within the central bore of the arrow shaft. The dampening materials in an embodiment may include, but not be limited to, silicon, epoxies or urethanes and selection of various dampening materials may provide for varying degrees of stiffness. The dampening effects of internal dampening materials decrease the initial deflection distance of the arrow and also serves to decrease the deflection with each oscillation. In addition, the dampening medium adopted in the present invention provides for an arrow having a selectable center of gravity location that has improved flight characteristics. Thus, the dampening materials adopted in the present invention provide for a selected location of center of gravity and a desired attnuation of oscillations.

Embodiments of a projectile are disclosed herein. According to various embodiments, a projectile includes a substantially solid core of a material, and two or more petals attached to the core. The two or more petals can be formed from the same material used to form the core and can include a trocar tip. A cavity can be bound by the core and inner surfaces of the plurality of petals.

A projectile or bullet for a firearm. The projectile tumbles upon impact with a target. The projectile may be tailored to control the location of the tumbling.

A projectile incorporates one or more spoiler-tabbed spinning disks to effect flow around the projectile and thus impart steering forces and/or moments. The spoiler tabs may be deployed only during steering phases of travel thus minimizing the drag penalty associated with steering systems. The disks are driven by motors and informed and controlled by sensors and electronic control systems. The spoiler tabs protrude through the surface of the projectile only for certain angles of spin of the spinning disk. For spin-stabilized projectiles, the disks spin at substantially the same rate as the projectile, but the disks may function in fin-stabilized projectiles as well. Any number of such spinning flow effector disks may be incorporated in a projectile, with the manner of functional coordination differing slightly for even and odd numbers of disks.
