    • A missile includes a payload assembly that has a pair of nosecones. The nosecones may be optimized for different environments and/or phases of flight, for example, having different shapes, different shell materials, different types of seals, and/or different separation mechanisms. The first (outer) nosecone may have a more streamlined shape, be made of more thermally-protective material, and may meet less stringent sealing requirements, than the second (inner) nosecone. Separation of the outer nosecone from the payload assembly may cause backward movement of a center of pressure of the payload assembly, bringing the center of pressure of the assembly closer to a center of gravity of the assembly. This may make the payload assembly easier to maneuver, for example, reducing or eliminating the need for intervention by an attitude control system, to maintain the payload assembly on a desired course.
    • 导弹包括一个有效载荷组件,它有一对无效的。 对于不同的环境和/或飞行阶段,例如具有不同形状,不同的外壳材料,不同类型的密封件和/或不同的分离机构,可以优化鼻锥体。 第一(外)鼻锥可以具有更加流线型的形状,由更多的热保护材料制成,并且可以满足比第二(内)鼻锥体更不严格的密封要求。 外部鼻锥与有效载荷组件的分离可能导致有效载荷组件的压力中心向后移动,使组件的压力中心更接近组件的重心。 这可以使得有效负载组件更容易操纵,例如,减少或消除对姿态控制系统的干预的需要,以将有效负载组件保持在期望的过程上。

    • A separable structure includes composite material that is separated or severed by a reactive pyrotechnic material. According to one embodiment, the structure includes a pair of composite laminate structural portions, each including multiple layers of composite material. The portions each extend into an overlap region, within which the composite layers of the two structural portions may be alternately placed, overlapping one another. A reactive material is also placed within this overlap region, for instance being in layers between pairs of the composite material layers. The reactive material may be ignited to cause destruction of the pyrotechnic material, and a matrix or resin material of the composite materials layers in the overlap region. This causes the structure to sever or separate along a line of separation within the overlap region. The separation may occur without need to sever fibers of the composite material.
    • 可分离结构包括由反应性烟火材料分离或切断的复合材料。 根据一个实施例,该结构包括一对复合层压结构部分,每个复合层压结构部分包括多层复合材料。 这些部分各自延伸到重叠区域中,两个结构部分的复合层可以交替放置在该重叠区域内,彼此重叠。 反应性材料也被放置在该重叠区域内,例如在复合材料层对之间的层中。 可以点燃反应性材料以引起烟火材料的破坏,并且重叠区域中的复合材料层的基质或树脂材料层。 这导致结构沿着重叠区域内的分离线断开或分离。 可能发生分离而不需要切断复合材料的纤维。
