Automated Impacts Routing (AIR) is a software system that uses a modified version of the A* algorithm by including environmental (atmosphere/terrain) effects coupled with shortest path calculations. It allows best and second-best path solutions as part of user selections. With multi-service U.S. Department of Defense (DoD) transitions, AIR has been developed and delivered as an…
This report surveys the state of the current digital-engineering (DE) tool landscape, with specific emphasis on applications relevant to the U.S. Department of Defense (DoD). The request originated from an inquiry seeking to understand the state of DE tools without disclosing personally identifiable information. The study excludes areas that have been heavily analyzed in prior…
The mixing of solid propellants for military and space applications remains largely an art rather than an exact science. Solid-propellant development requires a thorough understanding of process parameters. Scaleup bias is a critical consideration in the development, scaleup, and production of new solid-propellant formulations.
Hyperspectral imaging systems are able to address critical challenges, ranging from detecting chemical, biological, radiological, nuclear, and explosives materials to identifying targets from remote distances. However, due to their complexity, these sensors are expensive to build, maintain, and operate. A promising solution that has been recently explored is to leverage the abundance of inexpensive and…
This report examines the development and potential military uses of drone motherships by China’s military, the People’s Liberation Army (PLA). While media attention has often focused on using crewed ships or airplanes as carriers for drones, the People’s Republic of China (PRC) appears to have developed several large unmanned aerial vehicle platforms (UAVs) that could…
The Defense Systems Information Analysis Center (DSIAC) received an inquiry regarding the state of materials and methods available for sealing the external joints in the outer mold line and the engines of U.S. Department of Defense hypersonic weapon systems. In this technical inquiry response report, DSIAC subject matter experts provide a discussion of the needs…
This report researches the application of a multibeam Luneburg lens antenna to provide an anti-jam and anti-spoofing solution for Global Navigation Satellite System signals in a single aperture. In addition, the antenna can provide a direction-finding capability when paired with traditional radar techniques, such as monopulse tracking, that utilize multiple simultaneous beams to compare signal…
The U.S. Department of Defense (DoD) has made some progress certifying additive manufacturing (AM) parts for airworthiness, but certification has been limited to the lab, with significant engineering and inspections required for each part. Over the last two decades, each branch of the DoD developed their own processes for AM certification, thus fragmenting certification and slowing the widespread acceptance of AM. The Federal Aviation Administration…
