Additive manufacturing (AM) processes such as laser powder bed fusion (LPBF) have received a great deal of attention due to their unique capability in producing parts with complex geometries. However, a major challenge limiting the application of LPBF today is the high variability in the quality of finished components. To address this challenge, HIDENN-AI, LLC and Northwestern University (NU) prop ...

Virtual EM proposes develop a massively parallel ASIC for orders of mangnitude speed up of electromagnetic simulations of thin optical lenses made of metamaterials. The ASIC will implement a prorietary algorithm and will deliver scalable run-times that cut the simulation time by more than 1000x compared to today's state-of-the-art simulators.

Through this proposed SBIR effort, QuesTek Innovations LLC will develop a physics-enhanced machine learning (ML) software to reduce exhaustive typical on-destructive testing or enable feed forward control methodologies for fabrication of high-quality additive manufacturing (AM) component. Process induced defects like keyholing and lack of fusion porosity are shown to be strongly correlated with AM ...

Hypersonic weapons are one of the main priorities of the Department of Defense (DoD) activities since China and Russia have such capabilities (e.g. the DF-ZF, designated by Pentagon as the WU-14, is a hypersonic missile delivery vehicle that has been operational by China since 2019).  Due to the importance of these adversarial threats, the Navy, Army, and Air Force have programs for developing hy ...

The US Navy is searching for a cost effective and novel solution for launchable mini-glider sensor platforms which can be of three standard size form factors. The Great Lakes Sound & Vibration, Inc. (GLSV) proposed glider will have the ability to be launched from the deck of various surface vessels and be able to survive a 48-hour service life in up to sea state 6 (SS 6) conditions. The GLSV glide ...

Metal-organic frameworks (MOFs) are advanced adsorbents with applicability to military and civilian applications including but not limited to chemical biological protection, chemical warfare agent decontamination, toxic industrial chemical remediation, medical oxygen delivery, and energy storage. These materials have been produced in ton-scale quantities and have seen commercial use in the electro ...

Our goal for this Navy SBIR project is to develop a TRL-7 prototype of the BRG with excellent long-term bias stability and shock and vibration insensitivity that can operate in a military temperature range (-50–80 °C) and optionally can operate at very high temperature (200 °C) (i.e. bias drift < 0.01 deg/hr, angle random walk < 0.005 deg/sqrt(hr), and scale factor stability < 100 ppm).  We ...

Composite materials have become ubiquitous over the past two decades with greater use in naval structures due to the high specific strength, stiffness, and toughness offered with respect to other engineering materials. While fiber reinforced polymers have found wide use in commercial applications, currently used materials are costly and require extended cure times which greatly increases manufactu ...

EPIR proposes to develop a HgCdTe (MCT)-based notch filter that is capable of autonomously attenuating pulses from an incoming mid-wavelength infrared (MWIR) laser threat while simultaneously transmitting scene energy critical to the normal operation of the imaging system. This filter uses two-photon absorption (TPA) nonlinear response of narrow bandgap semiconductor materials to attenuate high la ...

SeaLandAire (SLA) will build on the work done in the Phase I effort to address the Navy’s need for a strengthened, full-duplex communications datalink between the surface unit of a sonobuoy and its suspended payload, as described in Navy SBIR Topic N221-023. SLA, along with our partner AFFOA, will develop, build and test prototype tethers.  We will design a fiber optic based tether which will a ...
