    • For use with a parachute used after ejection from an aircraft, a discard assembly (12) fordisconnecting a parachute deployment mechanism (16) from the parachute (14) in response to the opening of the parachute by a preselected amount. The discard assembly includes a pair of releasably interconnected rods enclosed in a slidable housing. An actuator assembly (10) is coupled to the housing and to the parachute and slides the housing away from one of the rods, thereby allowing them to disconnect, upon opening of the parachute by the preselected amount. The actuator assembly comprises a pair of rings coupled to the parachute on opposite sides of the parachute vent, and a pair of lanyards (18,20) coupled to the housing and to the parachute, with each lanyard passing through one of the rings. The force generated by the transverse expansion of the opening parachute is transmitted via these rings and lanyards to actuate the discard assembly. The deployment mechanism can include a drogue parachute and a rocket, and four rings and lanyards can be used to add redundancy.
    • 用于在从飞行器弹出之后使用的降落伞,用于响应于降落伞的打开以预选量而将降落伞展开机构(16)与降落伞(14)断开连接的丢弃组件(12)。 丢弃组件包括一对可释放地互连的杆,其包围在可滑动的壳体中。 致动器组件(10)联接到壳体和降落伞并且滑动壳体远离杆中的一个,从而允许它们在降落伞打开预定量时断开。 致动器组件包括在降落伞通气口的相对侧上联接到降落伞的一对环,以及耦合到壳体和降落伞的一对系索(18,20),每个系索穿过其中一个环。 由开式降落伞的横向膨胀产生的力通过这些环和系绳传递,以驱动丢弃组件。 部署机制可以包括锥形降落伞和火箭,并且可以使用四个环和挂绳来增加冗余。

    • A crewmember (12) is positioned within an ejection seat or other escape device (10). The escape device (10) is ejected from the aircraft or other flying vehicle when it is desired to effect an escape. At the start of ejection, the altitude, sink rate and roll angle of the escape device (10) are determined, by appropriate sensors (128, 132). A microprocessor (66) is used for dividing the altitude by the sink rate to obtain a first time value. The microprocessor (66) is used to divide the roll angle by a desired rate of roll angle correction, to obtain a second time value. The second time value is subtracted from the first time value to obtain a third time value, t c . In response to t c being larger than a predetermined value, the microprocessor (66) controls separation to subject the crewmember (12) to a relatively low injury risk level. In response to t c being smaller than said predetermined time value, the microprocessor (66) controls separation to occur faster, attended by the crewmember (12) being subjected to a higher injury risk level.
    • 机组人员(12)位于弹出座位或其他逃生装置(10)内。 当需要逃逸时,逃生装置(10)从飞行器或其他飞行器中弹出。 在喷射开始时,由适当的传感器(128,132)确定逃生装置(10)的高度,下沉速率和侧倾角。 微处理器(66)用于将高度除以吸收速率以获得第一时间值。 微处理器(66)用于将滚动角度除以所需的倾斜角修正率,以获得第二时间值。 从第一时间值减去第二时间值以获得第三时间值tc。 响应于tc大于预定值,微处理器(66)控制分离以使机组成员(12)受到相对较低的伤害风险等级。 响应于tc小于所述预定时间值,微处理器(66)控制分离发生得更快,由机组成员(12)承受较高的伤害风险等级。
