CORVID TECHNOLOGIES, LLC — Department of Defense STTR Phase I: A20B-T001

Description

Long Range Precision Fire (LRPF) systems are an important class of advanced weapon systems which can engage targets at long ranges with high degrees of accuracy. The Army seeks novel material solutions such as Phase Change Materials (PCM)s for LRPF Platforms to improve thermal management and structural integrity while exposed to extreme environments while keeping electromagnetic properties such as transmittivity in mind. Corvid proposes utilizing a multi-length scale modeling and simulation strategy to create a novel layered surface coating design which combines a structural material with multiple solid-solid PCMs to create a surface coating that has a gradated hierarchal response to increasing temperature while maintaining strength in extreme. Corvid will use atomistic techniques such as DFT and MD to predict novel PCM formulations with tailored thermomechanical and electromagnetic properties. Corvid will then leverage it’s in house topology optimization code to create novel PCM meta material designs which will optimize the thermal response of the PCM and the mechanical strength of a secondary load bearing material. The effectiveness of the meta material will then be tested utilizing Corvid’s coupled thermal-structural solver built into its massively parallel hydro-structural code Velodyne. Corvid will also be partnering with PennState University for initial prototyping of Corvid’s novel PCM meta-material designs.
