A modern-day cell phone packs quite a wallop when it comes to computing technology and capability. But most cell phones barely come with a “quick start guide,” let alone an instruction manual that spells out how to use all the features. Cell phone companies have mastered the interface between humans and technology, making their use…
The Defense Systems Information Analysis Center (DSIAC) was asked how combustion efficiency can be estimated for a liquid-fueled ramjet flying in the Mach 2-3 range with a given combustor length or bulk flow residence time. In particular, DSIAC was asked for some sort of data or an empirical/analytical model that has been validated with data, rather than non-computational fluid dynamics solutions, that can be used…

Reliability is the probability that an item will perform its intended function for a specified period under stated conditions. It has a significant impact on operating and sustainment costs within the U.S. Department of Defense (DoD), which typically represent 70% of the program’s total life-cycle costs [1].
Modeling and simulation are key for the iterative development of thermal protection systems (TPS’s) for hypersonic weapons. In this work, the temperature-dependent flexural strength (FS) of α-SiC ceramic is predicted given Young’s modulus, Poisson’s ratio, and temperature. An artificial neural network (ANN) surrogate model is created to retain property-performance prediction while increasing computation speed.
In 2022, the U.S. Navy installed the first-ever permanent metal AM machine aboard a U.S. naval vessel. This technology is projected to be groundbreaking by reducing resupply logistics and diminishing obsolescence: “For the Navy, the greatest immediate potential is in the less-exotic field of logistics” [1].
The U.S. Naval Air Warfare Center Aircraft Division (NAWCAD) Verification, Validation, and Accreditation (VV&A) Branch has developed and is executing a cost-effective, risk-based VV&A process for models and simulations (M&S) used to support the U.S. Department of Defense (DoD).
The DSIAC Journal is a publication of the Defense Systems Information Analysis Center (DSIAC). DSIAC is a DoD Information Analysis Center (IAC) sponsored by the Defense Technical Information Center (DTIC) with policy oversight provided by the Office of the Under Secretary of Defense (OUSD) for Research and Engineering (R&E). DSIAC is operated by the SURVICE…
The Defense Systems Information Analysis Center (DSIAC) is researching the development of terrain-based digital twins and vision-based navigation for advancing low-flying aerial systems’ capabilities. This technology can be at any technology readiness level. Applications for uncrewed systems would also be of interest. If you are interested in collaborating, please email the DSIAC analyst John Clements…
The Aircraft Survivability Symposium is a SECRET//NOFORN event, and all attendees must submit and keep a completed DD Form 3150 on their person at all times to attend. The presenters will discuss survivability technologies, survivability…
Hosted by the Global Special Operations Forces (SOF) Foundation, the 2022 Special Air Warfare Symposium will be held in Fort Walton Beach, Florida, the home of Air Force Special Operations Command (AFSOC). Though much of…
DSI’s 10th Annual Automated Intelligence, Surveillance, and Reconnaissance (ISR) and Battle Management Summit will provide the DoD, military services, intelligence community, industry, and academia the opportunity to discuss ways to modernize ISR systems for the…
This conference is focused on the tactical wheeled vehicle industry and its support to the U.S. Department of Defense and our nation’s Warfighters. The information and dialogue presented at this conference will discuss the design,…
Attended by DoD officers, enlisted members, civilians, and veterans, this warfighting symposium will focus on the critical concerns and challenges of joint warfare in every corner of the globe. Drawing speakers from combatant commands, as…
Chairman/Founder Desert Works Propulsion, LLC
Mr. Patterson has 40 years’ experience in spacecraft electric propulsion (EP), including 37 years with NASA Glenn Research Center in Cleveland, OH, where he served as Senior Technologist for In-Space Propulsion until retirement in December 2021. During his NASA tenure, he worked to transition EP technologies to commercial and National Security Space missions. In 2022, he founded Desert Works Propulsion LLC to accelerate fielding of high-performance EP in support of U.S. commercial and military missions, providing consulting, design, and manufacturing.
