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 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 system for controlling the trajectory of a launched projectile. More particularly, a method for correcting the projectile jump displacement of a launched projectile after it is released from a vessel using on-board G-hardened accelerometers orthogonally mounted along the longitudinal axis of the projectile. Deviation from an intended flight path is corrected by firing selected trajectory diverting thrusters mounted around the periphery of the projectile. Eliminating or reducing projectile jump, or the angular deviation of the flight path of a projectile relative to its intended trajectory, will greatly increase the accuracy of gun fired projectiles.
