Automated Impacts Routing – Path Optimization Through Adverse Atmospheric Effects and Obstacles

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…

What is the current state of the digital-engineering (DE) tool landscape, with a focus on application to the U.S. Department of Defense (DoD)?

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…

At the conclusion of a development campaign for a new solid propellant, should rocket motors be loaded and tested from the first-production scale mix?

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.

Illustration of the Process of Converting HSIs to Color and Reconstructing Hyperspectral Data From Color Images.

Can infrared (IR) hyperspectral imagery be acquired from IR multispectral sensors?

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…

Notable Technical Inquiry

Qualification and Certification of Powder Bed Fusion Additively Manufactured Components

Additive manufacturing (AM) is, and has been, a technology gaining traction for replacement parts and optimally designed structures throughout industry. However, with the lack of military or U.S. Department of Defense (DoD)-approved qualification and certification (Q&C) processes (outside of NASA standards), the utilization of AM throughout the Services and DoD certainly is not as trusted when compared to traditional manufacturing processes. Due to the lack…
