Publication number: 20230365476Abstract: The present invention relates to methods and processes to prepare pre-mixed compositions that can be combined to form pyrotechnic compositions in mixed multiple parts. In exemplary embodiments, a binder curing agent ingredient is premixed with pyrotechnic fuels and can also include other pyrotechnic additives and processing aides. Other binder ingredients such as a binder resin can be premixed with the pyrotechnic oxidizers and can also include other pyrotechnic additives and processing aides. The resulting mixtures are not explosive and are much safer to handle and easier to store for extended shelf-life over a final pyrotechnic composition. Further, the pre-mixed mixtures can be stored in bulk until needed and rapidly combined to achieve the final pyrotechnic composition.Type: ApplicationFiled: July 21, 2023Publication date: November 16, 2023Applicant: The United States of America, as represented by the Secretary of the NavyInventors: Christina Yamamoto, Anthony P.

Patent number: 11125545Abstract: The present invention is a pyrotechnic time delay system that is improved over prior-art designs. Specifically, the system described herein comprises at least one delay element. The delay element or delay dements each have an input charge, a delay composition, and an output charge. Both the input charge and the output charge are igniter compositions and are comprised of the same components despite having different functional goals. The input charge and output charge compositions preferably contain titanium, manganese dioxide, and polytetrafluoroethylene. The delay composition may be modified from current formulations to include manganese and manganese dioxide, or tungsten and manganese dioxide. The system disclosed herein may be comprised of one delay element, or it may be modular wherein multiple delay elements are connected in series.Type: GrantFiled: February 8, 2018Date of Patent: September 21, 2021Assignee: U.S. Government as Represented by the Secretary of the ArmyInventors: Anthony P. Shaw, Jay C. Poret, Lori J. Groven, Joshua Koenig, Jason Brusnahan

Patent number: 9938203Abstract: A novel pyrotechnic composition comprising nanostructured crystalline boron phosphide and oxidizer such as potassium nitrate wherein the crystalline boron phosphide is synthesized by a self-propagating high-temperature reaction. The nanostructured crystalline boron phosphide and oxidizer pyrotechnic composition unexpectedly emits smoke and green flame upon ignition.Type: GrantFiled: February 10, 2017Date of Patent: April 10, 2018Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Anthony P. Shaw, Jason Brusnahan, Jay C. Poret, Lauren A. Morris, Christopher D. Haines, Zhaohua Luan

Patent number: 9790093Abstract: A simplified method for synthesizing boron phosphide at high yields. The method requires mixing of boron phosphate and magnesium metal without diluents into a homogenous mixture, loosely packing the mixture at less than 20,000 psi and igniting the mixture using an energy input that is not greater than 20% of the reaction energy output to create a self-propagating high-temperature reaction wherein the boron phosphate and magnesium metal is completely burned during the reaction to synthesize boron phosphide at high yields.Type: GrantFiled: January 19, 2016Date of Patent: October 17, 2017Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Zhaohua Luan, Lauren A. Morris, Anthony P. Shaw, Christopher D. Haines, Jay C. Poret
