    • Embodiments of a launch lock assembly are provided, as are embodiments of a spacecraft isolation system including one or more launch lock assemblies. In one embodiment, the launch lock assembly includes first and second mount pieces, a releasable clamp device, and an axial gap amplification device. The releasable clamp device normally maintains the first and second mount pieces in clamped engagement; and, when actuated, releases the first and second mount pieces from clamped engagement to allow relative axial motion therebetween. The axial gap amplification device normally residing in a blocking position wherein the gap amplification device obstructs relative axial motion between the first and second mount pieces. The axial gap amplification device moves into a non-blocking position when the first and second mount pieces are released from clamped engagement to increase the range of axial motion between the first and second mount pieces.
    • 提供发射锁组件的实施例,如包括一个或多个发射锁组件的航天器隔离系统的实施例。 在一个实施例中,发射锁组件包括第一和第二安装件,可释放夹紧装置和轴向间隙放大装置。 可释放的夹紧装置通常将第一和第二安装件保持在夹紧接合状态; 并且当被致动时,将第一和第二安装件从夹紧的接合件释放以允许它们之间的相对轴向运动。 轴向间隙放大装置通常位于阻挡位置,其中间隙放大装置阻碍第一和第二安装件之间的相对轴向运动。 当第一和第二安装件从夹紧接合松开时,轴向间隙放大装置移动到非阻挡位置,以增加第一和第二安装件之间的轴向运动范围。

    • A payload launch lock mechanism includes a base, a preload clamp, a fastener, and a shape memory alloy (SMA) actuator. The preload clamp is configured to releasibly restrain a payload. The fastener extends, along an axis, through the preload clamp and into the base, and supplies a force to the preload clamp sufficient to restrain the payload. The SMA actuator is disposed between the base and the clamp. The SMA actuator is adapted to receive electrical current and is configured, upon receipt of the electrical current, to supply a force that causes the fastener to elongate without fracturing. The preload clamp, in response to the fastener elongation, either rotates or pivots to thereby release the payload.
    • 有效载荷发射锁定机构包括基座,预载夹具,紧固件和形状记忆合金(SMA)致动器。 预载夹具被配置为可释放地约束有效载荷。 紧固件沿着轴线延伸穿过预压夹具并进入基座,并且向预载夹具提供足以约束有效载荷的力。 SMA致动器设置在基座和夹具之间。 SMA致动器适于接收电流,并且在接收到电流时被配置为提供使紧固件伸长而不断裂的力。 响应于紧固件伸长,预紧夹具旋转或枢转,从而释放有效载荷。
