摘要: A gas generant composition for an automotive inflatable restraint system is provided with a fuel having a thermally stable crystalline hydrate compound with a water release temperature of greater than or equal to about 140° C. The thermally stable crystalline hydrate compound serves as a ballistic modifier, which can serve to increase burn rate, reduce pressure sensitivity, reduce temperature sensitivity, and the like. The thermally stable crystalline hydrate compound may be selected from the group consisting of: a copper phthalate hydrate, copper pyromellitate dihydrate, copper fumarate dihydrate, copper (3-nitrophthalate) dihydrate, and combinations thereof.

摘要: The present disclosure generally pertains to green oxidizer compositions and method of synthesizing and using the same. Such green oxidizers are stable, may be used in conventional bipropellant thrusters, including, but not limited to LDACS applications, and offer several benefits over conventional oxidizers with respect to toxicity and/or corrosion. The present disclosure also relates to methods of synthesizing poly-nitrated oxetane, a green oxidizer, in an Argon-rich environment.

摘要: A high energy explosive having reduced shock sensitivity for tactical weapon platforms to increase the safety margins to the warfighter if the weapon became involved in an unplanned event on the battlefield. The high energy explosive having a reduced crystalline particle size below about 30 microns, preferably 10 microns, and coated with a thermoplastic elastomer, which is capable of being compressed into a warhead configuration and attached to a weapon. The high energy explosive having a greater than 25% reduction in shock sensitivity compared to the same crystalline energetic material without undergoing size reduction prior to being coated.

摘要: Methods of diverting fluid flow, controlling fluid loss, and/or providing zonal isolation in subterranean formations are provided. In some embodiments, the methods comprise: providing a particulate material that comprises an electrically controlled propellant; placing the particulate material in at least a first portion of the subterranean formation; introducing a treatment fluid into the subterranean formation; and allowing the particulate material to at least partially divert the flow of the treatment fluid away from the first portion of the formation.

摘要: Detonation control modules and detonation control circuits are provided herein. A trigger input signal can cause a detonation control module to trigger a detonator. A detonation control module can include a timing circuit, a light-producing diode such as a laser diode, an optically triggered diode, and a high-voltage capacitor. The trigger input signal can activate the timing circuit. The timing circuit can control activation of the light-producing diode. Activation of the light-producing diode illuminates and activates the optically triggered diode. The optically triggered diode can be coupled between the high-voltage capacitor and the detonator. Activation of the optically triggered diode causes a power pulse to be released from the high-voltage capacitor that triggers the detonator.

摘要: A process for converting a crystalline energetic material to an amorphous energetic material that is less susceptible to accidental detonation initiation by mechanical insults. The process includes forming the amorphous energetic material as a deposition of a vapor of the crystalline energetic material sublimed from a hot surface in a vacuum. The deposition is onto a cryogenically cold surface of a dry ice layer. The deposition solidifies as a layer of amorphous energetic material. Subliming the dry ice layer therein breaking the layer of amorphous energetic material into a powder of the amorphous energetic material; and collecting the powder.
