    摘要： A clustered, fixed cant, throttleable rocket assembly (102) is used to propel and a steer a vessel (100) in terrestrial or extraterrestrial applications. The fixed cant of each of at least three individual rocket engines (104, 106, 108) in the cluster provides the steering input to the overall assembly (102). More specifically, by changing the propellant flow rate to the individual rocket engines (104, 106, 108) relative to one another, the overall thrust vector of the rocket assembly (102) may be selected to provide a desired steering input to the vessel (100). A measured vessel orientation may be compared with a desired vessel orientation to determine what steering input is required to achieve the desired vessel orientation.

    摘要： A throttleable exhaust venturi (700) is described herein that generates strong suction pressures at an exhaust outlet (718) by accelerating an incoming ambient fluid stream with the aid of a venturi to high gas velocities and injecting a combustion exhaust stream into the ambient fluid stream at an effective venturi throat (728). A mixing element (544) downstream of the venturi throat ensures that the mixed fluid stream recovers from a negative static pressure up to local atmospheric pressure. A physical (724) and the effective (728) throat of the venturi (700) are designed to promote mixing and stabilize the ambient fluid flow to ensure that high velocity is achieved and the effective venturi is operable over a variety of combustion exhaust stream mass flow rates.

    摘要： Disclosed are materials of variable density or tiered porosity micro-fluidic porous media structures of sintered metal or other materials, and methods of making same. An embodiment discloses an aluminum porous media element of variable density having a tiered porosity micro-fluidic media structure. A method of making the aluminum porous media element disclosed herein includes mixing a binding agent with a metal powder to generate a first mixture, heating the first mixture to a sub metal sintering temperature to get a homogeneous composite of the metal powder and heating the homogeneous composite to a metal sintering temperature to sinter-bond the metal powder to get a porous media of first porosity.

    摘要： An apparatus and system disclosed herein provides detonation wave arrestor including a detonation wave deflector and a burst element. The detonation wave arrestor disclosed herein attenuates and defects the propagation of a detonation wave characterized by a supersonic flame front propagation. The detonation wave arrestor provides deflection of detonation wave towards the burst element. The rupture of the burst element provides venting of hot gases remaining from the detonation, thus providing separation and attenuation of combusted gas residuals. The detonation wave arrestor disclosed herein may be used in a combustible fuel delivery system.

    摘要： An alternative or supplement to combustion within an engine is decomposition of nitrous oxide into two parts nitrogen, one part oxygen. This decomposition releases thermal energy that may be captured and converted to useful work. Traditional combustion engines are limited to oxidizer / fuel ratio ratios near the proportional mixture of fuel and oxidizer that achieves complete combustion of the fuel. The presently disclosed technology increases the oxidizer / fuel ratio above that of all traditional combustion engines and still achieves useable power output primarily through decomposition of nitrous oxide. Decomposition of nitrous oxide into nitrogen and oxygen, in an engine outputs two parts nitrogen and one part oxygen, which is roughly equivalent to oxygen rich atmospheric air. Output of carbon dioxide and other undesirable chemical compounds is avoided when compared to combustion of a carbon-hydrogen fuel and an oxidizer containing oxygen.

    摘要： Monopropellant and pre-mixed bipropellant storage and supply systems for rocket engines and other work producing systems are subject to damage when detonation progresses upstream from a combustion chamber to and through supply lines. Interposing one or more micro porous or micro fluidic elements into the supply conduit can limit the flame front that accompanies such unintended detonation, but inevitably restrict the flow of the propellant to the combustion chamber. A tiered micro fluidic element where a bulk of the element has relatively large pores but forms a structurally robust supports a second, relatively thin region having appropriately small mean pore diameter provides an effective flashback barrier that can resist catastrophic failure during such detonations. Such elements can be used in isolation, or they can be incorporated into detonation wave arrestors or pressure wave-triggered cut-off valves or the like to decrease the incidence of unintended detonations.
