摘要： A lightweight, relatively inexpensive rocket nozzle assembly which is heat resistant, ablative and electrically insulating. The body of the nozzle is molded in fibre reinforced thermosetting resin integrally with a forward metallic retaining ring, a rear metallic fin supporting ring and an electrical contact ring. A graphite throat insert is also provided and helical vanes are integrally molded into the rear portion of the nozzle to effect rotary motion of the exhaust gases. Wrap around fins are secured externally of the nozzle and provided with a retainer ring-shear pin assembly to hold the fins in the closed position for transport, and spring means to deploy the fins after firing and shearing of the shear pins.

摘要： A shear pin assembly suitable for use in a rocket retention and release system is provided. Each shear pin has a head and a shank with a passageway extending axially along the length of the shear pin. In the rocket release system, the shear pin connects a shear pin ring to the rear end of the rocket. A hole to receive the shear pin is provided in both the shear pin ring and the rear end of the rocket. The hole in the ring extends completely therethrough and has a diameter less than the diameter of the hole in the rocket. The passageway in the pin has parallel sides in longitudinal cross-section at the head end of the pin and sides which taper inwardly towards the shank end of the pin at the shank end. When the pin is inserted into the holes to connect the ring and rear end of the rocket together, the pin is expanded by a mandrel so that a shank end portion of the pin in the hole of the rocket fills the cross-section of the hole. Preferably a solid plug is then inserted in the passageway of the pin by means of a punch. When inserted in the pin, the plug is located entirely in the shank end portion of the pin located in the hole in the rear end of the rocket. Preferably the outer end of the inserted plug is located just below the shear plane formed between the ring and the rocket.

摘要翻译： 提供适用于火箭保持和释放系统的剪切销组件。 每个剪切销具有头部和柄部，其具有沿着剪切销的长度轴向延伸的通道。 在火箭释放系统中，剪切销将剪切销环连接到火箭的后端。 在剪切销环和火箭的后端均设有一个用于接收剪切销的孔。 环中的孔完全延伸通过，其直径小于火箭中孔的直径。 销中的通道在销的头端处的纵向横截面具有平行的侧面，并且在柄端部处朝向销的柄端部向内逐渐向内倾斜。 当销插入孔中以将火箭的环和后端连接在一起时，销被心轴扩张，使得火箭的孔中的销的柄端部填充孔的横截面 。 优选地，通过冲头将固体塞插入销的通道中。 当插入销时，插头完全位于位于火箭后端的孔中的销的柄端部。 优选地，插入的插塞的外端位于形成在环和火箭之间的剪切平面的正下方。
