    • A fin deployment system for missiles and munitions that deploys and activates straight flat fins for roll control authority. The fin deployment system employs numerous design features, among which are the following: A wrap-around fin concept generates space-savings within a projectile body whereby the fins are arranged in a wrapped configuration around a boomtail structure. The fins may be constructed of a super-elastic material; the system eliminates mechanical means of deploying the wrapped fins, eliminating the need for springs to deploy the fins. The fin deployment achieves substantial space savings for increasing the onboard towing capacity of electronic packaging or lethality in the missiles and munitions systems, while at the same time providing a good roll control authority during flight by enabling a straight fin deployment resulting from the use of super-elastic materials.

    • A kinetic energy penetrator with a longitudinal axis may include a forward segment having a lateral surface, a rear surface, and at least one air bleed channel extending from the lateral surface to the rear surface. A second segment may be disposed aft of and torsionally engaged with the forward segment. The second segment may include a front surface adjacent the rear surface of the forward segment. The forward and second segments may each be asymmetric about the longitudinal axis of the penetrator. When the penetrator is in flight, bleed air through the bleed channels may impinge on the front surface of the second segment. The second segment may separate from the front segment. Kinetic energies of each of the forward and second segments may be less than about 75 joules upon impact with a ground surface.

    • A variable drag projectile stabilizer is utilized by a training projectile to match the trajectory of a tactical projectile for up to 3 km while having a range limitation of 8 km. The stabilizer applies supersonic flow phenomena to alter the aerodynamic characteristics of a training projectile while in free flight to fulfill this requirement. The stabilizer uses a cowling supported by struts to provide tail lift and ensure a stable flight path. Supersonic flow is established through ducts formed by the cowling and struts when launched from a weapon. The flow remains supersonic until the projectile reaches the desired range but then quickly becomes subsonic (choked) due to shock waves emanating from interior angles in the ducts. The geometry of the ducts can be designed to create different shock wave patterns within the ducts. The variance of leading edge location, leading edge angle, cowling intake angle, and flight Mach number influences the shock patterns within the ducts and consequently, the range of the projectile.
    • 训练射弹使用可变拖弹弹稳定器,将战术射弹的轨迹与距离限制为8公里相距3公里。 稳定器采用超音速流动现象来改变训练射弹的空气动力特性,同时在自由飞行中满足这一要求。 稳定器使用由支柱支撑的整流罩来提供尾部提升,并确保稳定的飞行路径。 超音速流动通过从武器发射时由罩和支柱形成的管道建立。 流体保持超音速,直到弹丸达到所需的范围,然后由于管道内角发出的冲击波,迅速变为亚音速(窒息)。 管道的几何形状可以设计成在管道内产生不同的冲击波形图案。 前缘位置,前缘角,整流罩角度和飞行马赫数的变化影响管道内的冲击模式,从而影响射弹的射程。
