摘要： An active bolt release arrangement includes a nut having nut portions adapted for radial movement, a sleeve part encircling the nut and having contact portions in contact with the nut portions in order to prevent the nut portions from radial movement, and a pyrotechnical actuator. The pyrotechnical actuator is adapted for, upon deployment, moving the sleeve part relative to the nut to a released position forming a release space allowing radial movement of the nut portions. The pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part a predetermined rotational distance to the released position, such that radial movement of the nut portions by formation of the release space is allowed, thereby causing release of a bolt connected to the bolt release arrangement.

摘要： The present invention relates to an active bolt release arrangement comprising a nut (11) having nut portions adapted for radial movement, a sleeve part (17) encircling the nut (11) and having contact portions (18) in contact with the nut portions in order to prevent the nut portions from radial movement, a pyrotechnical actuator adapted for, upon deployment, moving the sleeve part (17) relative to the nut (11) to a released position forming a release space allowing radial movement of the nut portions. The pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part (17) a predetermined rotational distance to the released position, such that radial movement of the nut portions by formation of the release space is allowed, thereby causing release of a bolt connected to the bolt release arrangement (19).
摘要翻译：主动螺栓释放装置包括具有适于径向移动的螺母部分的螺母，环绕螺母的套筒部分，并且具有与螺母部分接触的接触部分以防止螺母部分径向运动，以及烟火致动器。烟火致动器适于在展开时将套筒部分相对于螺母移动到释放位置，形成允许螺母部分径向运动的释放空间。烟火执行器布置成在部署时将套筒部分转动到释放位置的预定旋转距离，使得允许通过形成释放空间的螺母部分的径向运动，从而导致连接到螺栓的螺栓的释放发布安排。
