    • A guidance method for a powered ballistic missile involves using an onboard computer to numerically simulate the flight path of the missile in real time, using a model with at least 3 degrees of freedom. The results of this simulation are used to update in real time an aim point and/or a predicted intercept point. An iterative process may be used in adjusting the aim point and/or the predicted intercept point. The process may be carried out until a specified number of steps have been completed, and/or until a specified heading error threshold of the aim point and a specified time of flight threshold have been achieved. The use of real time updating of an aim point of the missile advantageously takes into account variations in missile velocity and position due to individual variations in the rocket motor of the missile.
    • 用于动力弹道导弹的指导方法涉及使用机载计算机实时模拟导弹的飞行路径,使用具有至少3个自由度的模型。 该仿真的结果用于实时更新瞄准点和/或预测的截距点。 迭代过程可用于调整目标点和/或预测截点。 可以执行该过程直到指定数量的步骤已经完成,和/或直到目标点的指定航向误差阈值和指定的飞行时间阈值达到。 使用实时更新导弹的目标点有利地考虑到由于导弹的火箭发动机的个体变化导弹速度和位置的变化。

    • A projectile (10) comprises a cylindrical body (12) with a first (leading) end (14) and a second trailing axially opposed end (16). An internal cavity (18) is formed between the ends (14 and 16) and holds a volume of propellant material (22). The first end (14) is closed by a nose (20) that is fixed to the body (12). The end (14) is sealed with a base seal (26) that seats a primer (24) for igniting the propellant (22). The primer (24) is located inboard of the second end (16) and the base seal (26) to reduce the likelihood of accidental activation. Seals (30) are formed about the body (12) for maintaining gas pressure of deflagrating propellant. The seals (30) may be formed integrally with the body (12) or separately from the body (12) and seated in respective grooves (40) formed circumferentially about the body (12). Also disclosed is a breech sleeve (810) shaped to complement the breech of the weapon and a throughway (816) defined by an internal surface, the projectile being able to pass through the throughway (816).
    • 射弹(10)包括具有第一(前)端(14)和第二后轴向相对端(16)的圆柱体(12)。 在端部(14和16)之间形成内腔(18),并保持一定体积的推进剂材料(22)。 第一端(14)由固定到主体(12)的鼻(20)封闭。 端部(14)用一个底座密封件(26)密封,底座密封件(26)安置用于点燃推进剂(22)的底漆(24)。 底漆(24)位于第二端(16)和底部密封件(26)的内侧,以减少意外激活的可能性。 围绕主体(12)形成密封件(30),用于维持爆燃推进剂的气体压力。 密封件(30)可以与主体(12)一体形成或与主体(12)分开形成,并且位于围绕主体(12)周向形成的相应的凹槽(40)中。 还公开了形状为补充武器的后膛和由内表面限定的通道(816)的后膛套筒(810),所述弹丸能够通过通道(816)。

    • A projectile having variable kinetic energy contains multiple propellant charges (14) that are able to be individually selected for ignition. Each charge (14) has a selectable initiator (15) that may be triggered by a wired or wireless firing system, preferably an inductive system, in order to determine the kinetic energy of the projectile. The projectiles are axially stacked for firing from the barrel of a weapon, with nose portion (11) shaped to seal against tail portion (12) of a leading projectile. Ignition gas exit ports (17) are located in nose portion (11) for propulsion of a leading projectile from the weapon. Alternative, the ports may be located in tail portion (12) for propulsion of each respective projectile. Charges (14) may be distributed around the longitudinal axis of body (10) of the projectile.
    • 具有可变动能的射弹包含能够单独选择点火的多个推进剂电荷(14)。 每个充电(14)具有可选择的启动器(15),其可以由有线或无线发射系统触发,优选地是感应系统,以便确定射弹的动能。 抛射体被轴向地堆叠以从武器的枪身射出,其中鼻部(11)成形为密封着前导射弹的尾部(12)。 点火气体出口(17)位于鼻部(11)中,用于推进前方的射弹从武器。 替代方案,端口可以位于尾部(12)中,用于推进每个相应的抛射体。 充电(14)可以围绕射弹的主体(10)的纵向轴线分布。

    • Methods and apparatus are provided for a low shock separation joint. The separation joint comprises a male member, a female member, and an explosive device. At least one projection is formed on the male and female members. Surfaces of the at least one projection on the male and female members are mated to one another to prevent separation under compressive and tensile forces. The explosive device is placed within a cavity of said female member. A method for reducing shock in a separation joint is provided. An explosive device in the female member of the separation joint is detonated. A volume increase of the explosive device bends flanges of the female member away from one another. Surfaces in intimate contact with one another are moved out of contact with one another to decouple the male member from the female member.
