    • Slush is made from a liquid using slush making systems or according to slush making processes. A jacketed vessel of the processes and the systems has an interior wall that defines an interior space. The interior space comprises a top and a bottom. The interior space has an average overall cross-sectional area taken through a vertical axis extending generally between the top and the bottom. The interior space also has a collection portion having an average collection portion cross-sectional area taken through the vertical axis that is less than the average overall cross-sectional area. The liquid is placed into the interior space and the interior walls are cooled. Slush forms on the interior walls and migrates to the collection portion. The collection portion is located at the interior space bottom when the slush density is higher than the liquid density and the collection portion is located at the interior space top when slush density is less than the liquid density. To facilitate the migration of the slush to the collection portion, at least a conical portion of the interior space has the general shape of a cone and the collection portion is located in the proximity of an apex of the conical portion, thereby helping to funnel the slush to the collection portion. The cryogenic liquid to be made into slush may be oxygen, nitrogen, hydrogen, helium, or water. The slush may be used to densify cryogenic liquids, such as cryogenic liquid propellants.
    • 泥浆由使用制浆系统的液体或根据制浆工艺制成。 工艺和系统的夹套容器具有限定内部空间的内壁。 内部空间包括顶部和底部。 内部空间的平均整个横截面面积通过一般在顶部和底部之间延伸的垂直轴线。 内部空间还具有收集部分,该收集部分具有通过垂直轴线截取的平均收集部分横截面积小于平均总横截面积。 液体被放置在内部空间中并且内壁被冷却。 在内墙上形成灰浆,并迁移到收集部分。 当泥浆密度高于液体密度时,收集部分位于内部空间底部,当灌浆密度小于液体密度时,收集部分位于内部空间顶部。 为了便于将浆料迁移到收集部分,内部空间的至少一个锥形部分具有锥体的大致形状,并且收集部分位于锥形部分的顶点附近,从而有助于漏斗 溜到收集部分。 待制成冷冻的低温液体可以是氧气,氮气,氢气,氦气或水。 泥浆可用于致密化低温液体,例如低温液体推进剂。

    • A liquid-solid propulsion system having a tank of liquid oxygen and a high pressure chamber loaded with solid grain fuel with a portion of the liquid oxygen being passed through a heat exchanger to convert the liquid oxygen to gaseous oxygen. The gaseous oxygen is directed to the chamber or solid grain fuel to induce a fuel rich gas burn that is directed to a thrust chamber which also receives liquid oxygen to increase the characteristic velocity of the exhaust and thereby provide the specific impulse of the propulsion system. The gaseous oxygen is also directed to the liquid oxygen tank to pressurize the flow of liquid oxygen from the tank. Valves are interposed to control the flow of liquid and gaseous oxygen to provide the required mixture ratio in the thrust chamber for optimum specific impulse or to terminate the thrust of the propulsion system. A method for providing the liquid-solid propulsion system is also disclosed.
    • 具有液氧罐的液固推进系统和装有固体颗粒燃料的高压室,一部分液氧通过热交换器以将液氧氧化成气态氧。 气态氧被引导到室或固体颗粒燃料以引起燃料丰富的气体燃烧,其引导到推进室,其还接收液体氧以增加排气的特征速度,从而提供推进系统的比冲量。 气态氧也被引导到液氧罐以对来自罐的液氧流进行加压。 插入阀以控制液体和气态氧的流动,以在推力室中提供所需的混合比,以获得最佳比冲量或终止推进系统的推力。 还公开了一种用于提供液固推进系统的方法。

    • An improved cryogenic propellant which can be utilized as an improved rocket fuel, hypersonic vehicle fuel, aircraft fuel, explosive, or coolant is described. The improved cryogenic propellant is illustrated by a mixture of liquid hydrogen and solid methane. As an example, an approximate 50/50 mixture by weight of liquid hydrogen and solid methane has a mixture density approximately 2.0 times that of liquid hydrogen alone. This increase in density is partially offset by a loss in ISP of about 8 percent, compared to that of liquid hydrogen alone, with oxygen. Broadly speaking, more of the improved fuel must be carried for a given mission to compensate for the loss in ISP. However, this weight penalty is offset by the 200 percent increase in density. Increased fuel density reduces fuel tank weight and drag.
    • 描述了可用作改进的火箭燃料,超音速车辆燃料,飞机燃料,爆炸物或冷却剂的改进的低温推进剂。 改进的低温推进剂由液态氢和固体甲烷的混合物说明。 例如,液体氢和固体甲烷的大约50/50重量份混合物的混合密度仅为单独的液态氢的约2.0倍。 与单独使用氢气的氢气相比,这一密度的增加部分被ISP的损失所抵消了约8%。 一般而言,为了补偿ISP的损失,必须为特定任务提供更多的燃料。 然而,这种重量损失被密度增加了200%所抵消。 燃料密度的增加可以降低油箱重量和阻力。
