Abstract: A settable pneumatic altitude detection device provides an electrical signal to a missile or projectile for arming and destructing the missile or projectile at preset altitudes. The present invention''s main structural elements are a pair of sphere supports which hold therein a rotatable sphere assembly. The sphere support structure has two spherically shaped gas bearing pads which are separated and fixedly held to a circularly shaped collar. Two separate gas supplies are operatively positioned in the sphere support structure and in the rotatable sphere. An electrical initiating signal causes a gas release mechanism and a time delay valve, for each gas supply, to controllably release gas therefrom. Gas is forced through peripherally positioned jet nozzles on the sphere, and through operatively positioned venting ports and calibrated orifices in the sphere support structure. After the missile is fired, the sphere is pneumatically uncaged from its polar supporting structure so that it can freely spin on a nearly frictionless gas cushion. A pneumatically controlled distance meter operatively located in the sphere activates pressure operated switches on the ascent and the descent of the missile trajectory. The aforesaid switches provide an electrical signal which arms the missile on ascent and causes the missile to self-destruct on descent.

Abstract translation: 可设置的气动高度检测装置为导弹或射弹提供电信号，用于在预设高度下布防和破坏导弹或射弹。 本发明的主要结构元件是一对球形支撑件，其中保持有可旋转的球体组件。 球体支撑结构具有两个球形的气体支承垫，它们被分离并固定地保持在圆形的套环上。 两个单独的气体供应器可操作地定位在球体支撑结构中并且在可旋转的球体中。 电启动信号使气体释放机构和每个气体供应的时间延迟阀可控制地从其中释放气体。 气体被迫通过球体上的外围定位的喷嘴，并且通过可操作地定位的排气口和球体支撑结构中的校准孔。 在导弹发射后，球体从其极性支撑结构中气动地开启，从而可以在几乎无摩擦的气垫上自由旋转。 可操作地位于球体中的气动控制距离计在导弹轨迹的上升和下降时激活压力操纵的开关。 上述开关提供一个电气信号，使导弹上升并使导弹在下降时自毁。
