Abstract: The incorporation of a nitrated pentaerythritol additive selected from theono-, di-, tri-, and tetra-nitrated pentaerythritols into hydrazine is effective in lowering the freezing point of the combination while enhancing the performance of the monopropellant by contributing to the total energy of the monopropellant combination. Hydrazine content varies from about 65 to 95 weight percent while the additive of a nitrated pentaerythritol varies from about 5 to about 25 weight percent. An optional additional additive of methyl alcohol from about 5 to about 20 weight percent can be employed with a corresponding adjustment in weight percent of hydrazine when said additive of methyl alcohol is employed in addition to said additive of said nitrated pentaerythritol.

Abstract: A thixotropic oxidizer gel comprising inhibited red fuming nitric acid (IA) as the carrier with lithium nitrate (LiNO.sub.3) suspended therein and gelled with a gellant agent of SiO.sub.2 having a mean particle size of 0.015 microns has the rheological properties which can be tailored to match those of MICOM GEL, a fuel gel.A thixotropic gelled fuel (MICOM GEL) has been of particular interest because of its increased safety, reduced sloshing, ease of pumping at zero gravity and ability to suspend high concentrations of high-energy ingredients. However, a gelled oxidizer has been desired for use with the gelled fuel to constitute a thixotropic gelled propellant system. The combination of a gelled fuel (MICOM GEL) and a gelled oxidizer is now a reality after the development of the thixotropic oxidizer gel disclosed above. Of major significance is the matching of the rheologial properties of the two gels so that an oxidizer/fuel (O/F) ratio shift does not occur with a temperature change. The development of the thixotropic oxidizer gel obviates the problems of O/F shift attributed to using a liquid IRFNA oxidizer with MICOM GEL. The combination of the thixotropic oxidizer gel comprising the carrier of IRFNA in weight percent amounts from about 55.0 to 86.0, the suspended LiNO.sub.3 in weight percent amounts from about 10.0 to 40.0, and the gellant agent of SiO.sub.2 in weight percent amounts from about 4.0 to about 5.0 with MICOM GEL fuel offers both high Isp and high density Isp which translates to significant increases in total system performance. This combination reflects a range increase to 160 percent of the present system.

Abstract: A high density inhibited red fuming nitric acid oxidizer gel is disclosed ich results in an improvement from 0.5% to about 1.0.% in the impulse over a baseline formulation containing 14% nitrogen tetroxide. An improvement from about 3.0% to about 6.0% is achieved in the density impulse baseline formulation. The higher density inhibited red fuming nitric acid is derived by adding from about 15 percent by weight to about 45 percent by weight percent of nitrogen tetroxide to nitric acid in an amount from about 80 percent by weight to about 40 percent by weight. The other ingredient of the oxidizer gel comprise a gellant of about 0-10 percent by weight, water from about 0-4 percent by weight, and an inhibitor agent of about 0-1 percent by weight. IRFNA is inhibited with phosphoric acid, iodine compounds, or hydrogen fluoride which is present in the oxidizer gel as an additive. The higher density IRFNA oxidizer gel or liquid can be used in airbreathing propulsion systems; a bipropellant formulation is used to provide variable thrust. The oxidizer can also be used with air turbo rocket propulsion systems to augment air combustion with fuel gases. It can be used in a liquid or gel/solid system wherein the oxidizer is sprayed in contact with a solid propellant.

Abstract: A pressure controlled pintle is employed in combination with a throttling quid, gel, or hybrid engine to provide a constant pressure and variable thrust from a single operating engine. As the propellants are throttled back and the chamber pressure drops, the pintle moves and closes the gap between the pintle and nozzle throat, thereby lowering the throat area and re-establishing the design chamber pressure related to pintle spring tension. By retaining the design pressure over a wide thrust range, the engine efficiency remains at the design value. This eliminates the drop of Isp due to pressure and keeps the cost of the system reasonable because only one engine is required. When a higher thrust is desired, a throttling valve in an injector increases the propellant flow rate, which causes a higher pressure in the combustion chamber. The constant pressure actuator moves the pintle to open the nozzle throat, which reduces the pressure to the design value. The design value may not be optimum. There are many size/temperature/volume trade off's relating to the missile as a whole which could move the design value from optimum. Because the pressure in the combustion chamber remains the same, the Isp is not greatly changed, but the thrust level increases because of the increase in the mass flow through nozzle. The combination provides substantially constant combustion chamber pressure for a single variable thrust bipropellant engine.

Abstract translation: 与节流液体，凝胶或混合发动机组合使用压力控制枢栓，以提供来自单个操作发动机的恒定压力和可变推力。 当推进剂被节流并且室压力下降时，枢轴移动并闭合枢栓和喷嘴喉部之间的间隙，从而降低喉部面积并重新建立与枢轴弹簧张力相关的设计室压力。 通过在宽推力范围内保持设计压力，发动机效率保持在设计值。 这样可以消除由于压力造成的Isp跌落，并且由于只需要一台发动机，因此可以保持系统的成本合理。 当需要更高的推力时，喷射器中的节流阀增加推进剂流速，这导致燃烧室中的较高压力。 恒压致动器移动枢轴以打开喷嘴喉部，这将压力降低到设计值。 设计值可能不是最佳的。 与导弹有关的许多尺寸/温度/体积的交易可以将设计值从最佳状态转移。 由于燃烧室内的压力保持不变，所以Isp不会发生很大的变化，但由于喷嘴质量流量的增加，推力水平升高。 该组合为单个可变推力双组元推进剂发动机提供基本恒定的燃烧室压力。
