Problems solved by technology

Thus, high energy density monopropellants with small quenching distances (e.g., sufficiently small fluid gaps, pores, and / or effective fluid channel diameters so that the flame cannot propagate through the channel) have traditionally been avoided, This is because the flashback failure mechanism is very difficult to control

Embodiment Construction

[0038] In the following description, for the purpose of explanation, a large number of specific details are presented to provide a sufficient understanding of the present invention. However, it is obvious that those skilled in the art can implement the present invention without a part of these specific details. For example, although different features belong to a specific embodiment, it should be understood that the features described for one embodiment can also be integrated with other embodiments. However, similarly, no single feature or multiple features of any of the described embodiments are indispensable to the present invention, because other embodiments of the present invention may omit such features.

[0039] figure 1 Shows a cross-sectional view of an exemplary single-component propellant propellant system 110 in an orbiter 100 that can utilize flashback suppression devices 102, 104, 106 according to the technology disclosed in the present invention, which includes a si...

Abstract

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.
