UASs in the Modern Electronic Battlefield
With dominance of the electromagnetic (EM) spectrum increasing in importance and U.S. military vehicles and systems being faced with an array of threats from various adversaries, control and management of the EM spectrum will determine where future battles are won or lost. Simultaneously, the use of unmanned aerial systems (UASs) in the battlefield for surveillance, targeting, and weapons delivery continues to rise.
Using Machine Learning for a Dynamically Coupled Fluid-Structure Interface
A dynamically coupled interface has been developed to determine the three-dimensional transient thermo-structural response of the hypersonic vehicle during its flight. Dynamic coupling is required when the change in aerothermal state, surface temperature, ablation, mass/momentum/energy transfer at the surface, and shape change of a hypersonic vehicle due to the thermal loading from the aerothermal environment couples with the structural solver. This results in a strong coupling between the two codes.
Microdiode Laser Primers – A Path Forward
The concept of using lasers to ignite propellant and energetic material is not new. At the U.S. Army Combat Capabilities Development Command-Armaments Center (DEVCOM-AC) at Picatinny Arsenal, NJ, the Army explored efforts to use external mounted lasers for medium- and large-caliber weapons systems, with modest success in the 1980s through 2010.
Perception and Navigation Algorithms for Legged Robots
Mobile robots, equipped with wheels, tracks, or legs, are designed to move from a start location to a goal in various indoor and outdoor environments. A key area of interest is making them capable of autonomously navigating diverse environments.
Analysis of Powder, Bullet, and Barrel Interactions
All ammunition makers and reloaders “know” that changing propellant type can affect the group size (dispersion) of the ammunition they make. Why changing powders affects bullet group size is more than a matter of propellant burnout prior to muzzle exit or some other easily definable characteristic. This article details the investigations undertaken to better understand this phenomenon and why it occurs.
