摘要： A solid rocket motor including a combustion chamber, in which propellant is ignited to produce combustion gas, and a nozzle having a throat with an effective flow area, implements a system and method to inject gas into the nozzle throat to control its effective cross sectional flow area. Controlling the effective cross sectional flow area of the nozzle throat in turn controls combustion chamber pressure, thus the burn rate of the propellant in the combustion chamber, and thus the thrust generated thereby.
摘要翻译：一种固体火箭发动机，其包括燃烧室，其中推进剂被点燃以产生燃烧气体，以及具有有效流动面积的喉部的喷嘴，实现了将气体注入喷嘴喉部以控制其有效截面流量的系统和方法区。控制喷嘴喉部的有效截面流动面积又控制燃烧室压力，从而控制燃烧室中的推进剂的燃烧速率，从而控制由此产生的推力。

摘要： A valve includes a valve body and a free floating poppet. The valve body includes an inlet, an outlet, and a fluid flow passage therebetween. The free floating poppet is disposed in the valve body, and is moveable between at least a closed position, in which the free floating poppet at least substantially restricts fluid from flowing through the fluid flow passage, and an open position, in which fluid is allowed to flow through the fluid flow passage. The free floating poppet includes a base section and a cutback section. The base section has a first cross sectional area. The cutback section has a second cross sectional area that is less than the first cross sectional area.
摘要翻译：阀包括阀体和自由浮动提升阀。阀体包括入口，出口和其间的流体流动通道。自由浮动提升阀设置在阀体中，并且可在至少一个关闭位置之间移动，在该关闭位置中，自由浮动提升阀至少基本上限制流体流过流体流动通道，并且允许流体被允许的打开位置流过流体流动通道。自由浮动提升阀包括底座部分和裁切部分。基部具有第一横截面积。切割部分具有小于第一横截面积的第二横截面积。

摘要： A method is provided for manufacturing a missile component for use in a high temperature environment, where the missile component has a flow passage therethrough and the flow passage has a shape. An apparatus manufactured by the inventive method is provided as well. The method includes the steps of depositing a first metal onto a mandrel having the shape of the flow passage to create a first metal layer, applying an insulating material on to the first metal layer to create an insulating layer, machining a predetermined shape into at least a portion of the insulating layer, and applying a second metal onto the machined insulating layer to create an outer shell layer.
摘要翻译：提供一种用于制造在高温环境中使用的导弹部件的方法，其中导弹部件具有穿过其中的流动通道，并且流动通道具有形状。还提供了通过本发明方法制造的装置。该方法包括以下步骤：将第一金属沉积到具有流动通道形状的心轴上以产生第一金属层，将绝缘材料施加到第一金属层上以形成绝缘层，至少将预定形状加工成绝缘层的一部分，并将第二金属施加到加工的绝缘层上以形成外壳层。

摘要： A nozzle for use in a hot gas valve is provided that includes a housing, an insert, and a throat retainer. The housing is constructed of an insulating material and has a flow path formed therein. The flow path has a throat section. The insert is made of material capable of maintaining structural integrity at a temperature up to about 5000° F. and is disposed at least partially in the throat section and has a flow path extending therethrough in fluid communication with the housing flow path. The throat retainer is constructed of material having insulating and ablative properties and is coupled between the housing and the insert and configured to retain the insert within the housing throat section.
