Abstract: A hydrogen fuel including a safety marker and a method and apparatus for adding the safety marker to the hydrogen fuel. The hydrogen fuel may be stored in a tank in a liquid phase and then heated to at least one of a gaseous phase and a supercritical phase. The safety marker may be added to the hydrogen fuel when the hydrogen fuel is in the at least one of the gaseous phase and the supercritical phase after heating the hydrogen fuel. The hydrogen fuel may be delivered in the at least one of the gaseous phase and the supercritical phase to a power generator, such as a gas turbine engine. The safety marker may be a visual safety marker, such as a noble gas, or an odorant.

Abstract: A high density, generally recognized as safe, hybrid rocket motor is described, having a density-specific impulse similar to a solid rocket motor, with good performance approaching or equal to a liquid rocket motor. These high density hybrid motors resolve the packaging efficiency/effectiveness problems limiting the application of safe, low cost hybrid motor technology.

Abstract: Various embodiments of a vortex hybrid motor are described herein. In some embodiments, the vortex hybrid motor may include a combustion zone defined by a fuel core and/or motor housing. The combustion zone may include an upper zone and a central zone that each contribute to thrust created by the vortex hybrid motor. In some embodiments, an injection port configuration is described that includes a proximal injection port that may be controlled for modulating a delivery of an amount of oxidizer for adjusting an oxidizer-to-fuel ratio. In some embodiments, a fuel core configuration is described that provides radially varying gradients of fuel in order to achieve desired thrust profiles. In some embodiments, the fuel core may include a support structure and/or a proximal end of a nozzle of the vortex hybrid motor may extend into the fuel core.

Abstract: The present invention relates to processes for making macromolecular networks, macromolecular networks made by such processes, and methods of using such macromolecular networks. Such process employs a low amount of amine compound as a reaction accelerant. The rates of chemical reaction are thereby easily controlled over several orders of magnitude, permitting efficient catalysis and control of reaction conditions needed to produce thermochemically stable macromolecular networks.

Abstract: A gas generant composition for an automotive inflatable restraint system includes one or more: fuels, such as guanidine nitrate; oxidizers, such as basic copper nitrate; and an alkaline earth zirconium oxide. The gas generant composition is substantially free of potassium perchlorate. The alkaline earth zirconium oxide may be barium zirconate (BaZrO3), calcium zirconate (CaZrO3), and/or strontium zirconate (SrZrO3). The alkaline earth zirconium oxide may be present at ≥about 0.1% by mass to ≤about 6% by mass of the gas generant composition. Such gas generants may be cool burning (e.g., a maximum flame temperature at combustion (Tc) of ≤about 1700K (1,427° C.)), have a linear burn rate of ≥about 20 mm per second at a pressure of about 21 MPa and a linear burn rate pressure exponent (n) of ≤about 0.35. Method of making such gas generants are also provided.

Abstract: Disclosed herein is an explosive composition for soft and wet ground. The explosive composition comprises an explosive comprising an oxidiser component in a water in oil emulsion or a water gel, and a bulking agent comprising discrete particles of a combustible substance. The combustible substance is water soluble but, in the explosive composition, migration of the combustible substance from the discrete particles to the oxidiser component is inhibited. Also disclosed is a method for delivering an explosive composition to a borehole, for example a borehole in soft and wet ground.

Abstract: The present invention relates to a water-based non-sensitized matrix or explosive suspension which itself has a rheological behavior such that it allows mechanically loading upward boreholes. This suspension behaves like a viscous liquid when it is forced to flow due to the action of a loading pump, and, however, has the characteristics of a soft solid when it is on standby once inside the borehole. The composition essentially consists of an aqueous solution of oxidizing salts and optionally water-soluble fuels and/or sensitizers, and one or more water-soluble polymers conferring the desired rheological characteristics. Particles of oxidizing salts with a grain size such that they enhance the rheological behavior characteristic of the suspension are dispersed in this aqueous solution.

Abstract: Gas generants comprising copper are provided that have improved slagging ability. In certain aspects, the gas generants include a fuel, an oxidizer comprising basic copper nitrate, and a large particle size endothermic slag-forming component, such as aluminum hydroxide (Al(OH)3). The gas generants may be cool burning, e.g., having a maximum flame temperature at combustion (Tc)≤about 1,900K (1,627° C.). The disclosure also provides methods of enhancing slag formation for a gas generant composition that comprises copper. Such methods enhance slag formation during combustion of the gas generant composition by at least 50%.
