Patent number: 11892023Abstract: A thermally stabilized fastener system and method is disclosed. The disclosed system/method integrates a fastener (FAS) incorporating a faster retention head (FRH), fastener retention body (FRB), and fastener retention tip (FRT) to couple a mechanical member stack (MMS) in a thermally stabilized fashion using a fastener retention receiver (FRR). The MMS includes a temperature compensating member (TCM), a first retention member (FRM), and an optional second retention member (SRM). The TCM is constructed using a tailored thermal expansion coefficient (TTC) that permits the TCM to compensate for the thermal expansion characteristics of the FAS, FRM, and SRM such that the force applied by the FRH and FRR portions of the FAS to the MMS is tailored to a specific temperature force profile (TFP) over changes in MMS/FAS temperature. The TCM may be selected with a TTC to achieve a uniform TFP over changes in MMS/FAS temperature.Type: GrantFiled: November 5, 2022Date of Patent: February 6, 2024Inventors: James Alan Monroe, Jeremy Sean McAllister, Jay Russell Zgarba

Patent number: 11835323Abstract: Munitions structures comprising one or more high strength reactive alloys, in particular reactive bulk metallic glasses, have significant amounts of inherent chemical energy. This energy may be discharged by subjection of the munitions structure to rapid impulsive loading and fragmentation in the presence of oxygen and/or nitrogen. A munitions structure can be configured in both large and small penetrators, e.g. warheads and bullets, with increased lethality. The lethality of these munitions structures is augmented by means of rapidly and simultaneously imparting both mechanical energy (kinetic energy through impact and fragmentation) and chemical energy (blast and/or fireball) to a target. A high-strength reactive alloy can substitute at least in part one or both of explosives and inert structural materials in conventional munitions systems to improve performance and reduce parasitic weight of structural casing.Type: GrantFiled: March 4, 2022Date of Patent: December 5, 2023Assignee: Washington State UniversityInventors: Yogendra M.
