摘要： A statically stabilized projectile may include a fixed tail boom that may be disposed in the through-bore of a sliding tail boom. The sliding tail boom may translate or extend rearward with respect to the fixed tail boom before the projectile exits a launch tube. The through-bore of the sliding tail boom may include a tapered portion. A tail boom sleeve may be fixed to a rear portion of the fixed tail boom. The tail boom sleeve may include a tapered portion that abuts the tapered portion of the through-bore when the sliding tail boom is in an extended position.

摘要： A projectile includes an elongated forebody and an aft section secured to the forebody. The aft section includes a pair of fins affixed to an aerodynamic, cylindrical section. The lift generated by the low-drag pair of fins is sufficient to counteract most foreseeable angles of attack to be experienced by the projectile. The aft section further includes a bearing that couples the aft section to the forebody of the projectile and is capable of allowing the aft section to rotate freely about the longitudinal axis of the projectile and independently of the forebody. Thus, during flight the aft section rotates into the maximum lift plane and provides a restoring moment to the projectile, thus providing necessary stability to the projectile while imparting minimum drag.
摘要翻译：射弹包括一个细长的前身和一个固定到前身的后部。后部包括固定在空气动力学圆柱形部分上的一对翅片。由低阻力对的翅片产生的升力足以抵消射弹所经受的最可预见的迎角。后部段还包括一个轴承，该轴承将后部部分连接到射弹的前体，并且能够使后部部分围绕射弹的纵向轴线自由旋转并且独立于前体。因此，在飞行期间，后部段旋转到最大提升平面，并为射弹提供恢复时刻，从而为抛射体提供必要的稳定性，同时施加最小的阻力。

摘要： A cartridge for a kinetic energy projectile, where the projectile has a deter of less than a gun bore diameter and the projectile is saboted in order to support and guide the projectile along the gun bore. The sabot 42 has a closing disk 48 which radially extends from the projectile or penetrator 41 to the internal diameter of the gun bore. The closing disk is positioned on the penetrator at a location spaced from an open end 14 of a cartridge case 49. A shell 13 extends from the closing disk to the open end 14 of the cartridge case. The shell 13 is positioned adjacent the internal diameter of the gun bore, and the shell 13 along with the sabot defines a sabot volume. The sabot volume along with the volume defined by the cartridge case is filled with propellant.

摘要： A soft-recovery projectile having an aft portion, a forward portion and a gas seal mounted between the portions. The aft portion includes a recoverable payload such as projectile components or the like. The forward portion includes a parachute that is attached to the payload and is stored in a housing which is separably attached to the payload. The housing includes an explosive charge which is slectively triggered to cause separation of the housing from the payload and deployment of the parachute. A fin assembly, mounted on the housing, exerts a destablizing moment on the projectile when it is oriented with the fin assembly directed into the flight path. The projectile is launched with the fin assembly as the nose and the payload as the tail. After launch, the destabilizing moment will reorient the projectile into a position where the payload is the nose and the fin assembly is the tail. In this position, the fin assembly exerts a stabilizing moment on the projectile. At this point, the parachute is deployed by triggering the charge and thereby separating the housing and fin assembly from the payload.

摘要： 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.
摘要翻译：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。
