    • A hold-down and release apparatus for a flight termination system having a terminal portion for holding-down and releasing a structural object which has an arrangement for attaching to the flight termination system. The hold-down and release apparatus includes several movable clamping segments provided on the terminal portion of the flight termination system that are engageable in a complimentary fashion with the attachment arrangement on the structural object for releasably attaching the structural object to the flight termination system. The hold-down and release apparatus also includes springs for biasing the movable clamping segments means in a disengaging direction that causes the clamping segments to disengage from the attachment arrangement on the structural object to release the structural object from the flight termination system. The hold-down and release apparatus further includes a release band attached to the movable clamping segments for preventing the disengaging movement of the movable clamping segments such that they remain engaged to the attachment arrangement of the structural object for releasably attaching the structural object to the flight termination system. The release band is held in position by two non-explosive actuators (NEAs), such that either one or both actuators may initiate the release and loosen the release band which allows the movable clamping segments to move under the urge of the biasing, springs to disengage the complimentary attachment arrangement from the attachment arrangement of the structural object, to release the structural object from the flight termination system.
    • 一种用于飞行终点系统的按压和释放装置,具有用于按压和释放具有用于附接到飞行终点系统的装置的结构物体的终端部分。 压紧和释放装置包括设置在飞行终端系统的终端部分上的多个可移动的夹紧段,其能够以与结构物体上的附接装置互补的方式接合,以将结构物体可释放地附接到飞行终点系统。 压紧和释放装置还包括弹簧,用于使分离方向偏置可动夹紧段装置,使得夹紧段与结构物体上的附接装置分离,以将结构物体从飞行终端系统释放。 压紧和释放装置还包括附接到可动夹紧段的释放带,用于防止可动夹紧段的分离运动,使得它们保持接合到结构物体的附接装置,以将结构物件可释放地附接到飞行 终止系统。 释放带由两个非爆炸致动器(NEAs)保持就位,使得一个或两个致动器可以启动释放并松开释放带,其允许可动夹紧段在偏压的推动下移动,弹簧到 将互补的附接装置与结构物体的附接装置分离,以将结构物体从飞行终点系统释放。

    • An improved spool assembly for non-explosive actuators used in electro-mechanical structural separation devices. The spool assembly includes two spool halves each having external surfaces and a generally flat internal surface, a unitary and integral internal member made of an electrically conductive material and having a link-wire portion and two electrical terminal portions, and an external wrap-wire wound around the two spool halves and having a connecting end connected to the link-wire portion of the unitary and integral internal member such that the wrap-wire tightly binds the two spool halves together to form a spool for retaining an external structural member. When an electrical current of a sufficient magnitude is applied through the electrical terminal portions of the unitary and integral internal member, the link-wire portion of the unitary and integral internal member will be heated, which reduces its tensile strength to a magnitude below a tensile stress exerted thereon by the connecting end of the wrap-wire, causing the link-wire portion of the unitary and integral internal member to be broken, which in turn causes the wrap-wire to be loosened, allowing the two spool halves to separate apart which permits displacement of the external structural member.
    • 用于机电结构分离装置中的用于非爆炸致动器的改进的卷轴组件。 卷轴组件包括两个卷轴半部,每个具有外表面和大致平坦的内表面,由导电材料制成并具有连接线部分和两个电端子部分的整体和整体内部部件,以及外部绕线缠绕 围绕两个卷轴半部并且具有连接到整体和整体内部构件的连接线部分的连接端,使得包裹线将两个卷轴半部紧密地结合在一起以形成用于保持外部结构构件的卷轴。 当通过整体和整体内部构件的电气端子部分施加足够大的电流时,整体和整体内部构件的连接线部分将被加热,这将其抗拉强度降低到拉伸强度以下 通过包线的连接端施加在其上的应力,导致整体和整体内部构件的连接线部分被破坏,这又导致包线被松开,从而允许两个卷轴二分隔开 这允许外部结构构件的位移。

    • A high-load capability non-explosive cable release mechanism for retaining the adjacent ends of two cables and releasing them upon receiving a signal from a remote source. The cable release mechanism has a casing for housing two non-explosive actuators (NEAs), which also has a center bore for housing a jaw and ramp assembly. Each NEA is connected to the jaw and ramp assembly for independently operating the jaw and ramp assembly to retain or release the proximal ends of the two cables. Upon receiving the signal by any one or both of the NEAs, the jaw and ramp assembly will release the adjacent ends of the two cables from the casing.
    • 高负载能力的非爆炸性电缆释放机构,用于保持两条电缆的相邻端,并在从远程电源接收到信号时释放它们。 电缆释放机构具有用于容纳两个非爆炸致动器(NEAs)的壳体,其也具有用于容纳钳口和斜坡组件的中心孔。 每个NEA连接到钳口和斜坡组件,用于独立操作钳口和斜坡组件以保持或释放两根电缆的近端。 在通过任何一个或两个NEAs接收到信号时,钳口和斜坡组件将从壳体释放两根电缆的相邻端部。
