ABSTRACT: When a structure breaks up following a blast event, it allows the blast wave to propagate through a new opening into another airspace; this continuation of the blast wave is called"secondary blast"and may cause damage to elements in the other airspace. Each step in this process is a candidate for some type of acceleration. Current assessment codes incorporate several Fast Running Model ...

ABSTRACT: High-performance computing (HPC) programmers and domain experts, such as those in the Air Force's research divisions, develop solvers for a wide variety of application areas such as modeling next generation aircraft and weapons designs and advanced image processing analysis. When developing software for HPC systems, the programmer should not spend the majority of their time optimiz ...

Current Mine Countermeasure (MCM) operations attempt to balance risk to commander"s intent and time via processes that are staff and time intensive. Existing tools such as MEDAL have helped to alleviate some of this, but those tools lack an comprehensive understanding of the uncertainties involved, and how those impact commander"s intent. Furthermore, existing tools are mostly passive, representin ...

In this SBIR program, AlphaSense, Inc. teamed with the Center for Non-destructive Evaluations at Iowa State University to develop a compact, low cost handheld sensor for non-destructive material case depth verification. In phase I, we have proven the feasibility of using an alternating current potential drop (ACPD) sensor for non-destructive measurements of case depth. Phase II will be focusing on ...

The revolution in simulation and virtual technologies for training is enabling learners to practice skills and learn in realistic environments. Researchers are also seeking to develop algorithms that can tailor learner practice to the estimated abilities and needs of individual students, offering the promise of individual adaptation to each learner"s dynamically evolving zone of proximal developme ...

ABSTRACT: A new generation of supersonic weapons will operate at Mach 3-6. Current radome materials are unable to withstand the heat generated at the temperatures associated with hypersonic flight. Mainstream Engineering is proposing an advanced cooling approach that helps to extend the performance of existing radome materials into the Mach 3-6 region. Making use of extensive CFD and thermal cont ...

This proposal addresses the single largest non-propulsion consumer of Navy shipboard power. The heating, ventilation, and air conditioning system of a combatant ship dissipates over 25% of the ships waste heat. However, a growing percentage (up to 87%) of the waste heat is due to equipment loads that are currently cooled with 80 degrees F air (produced by a chilled water supply at 40-45 degrees F) ...

Efforts to replace metals with composites in shipboard applications have emphasized the use of brominated vinyl esters as fire-retardant polymers. Despite their relatively low cost and ease of fabrication, such halogenated polymers produce toxic and potentially carcinogenic gases; their compatibility with carbon fibers is also less than desirable. There is thus a need for environmentally friendly ...

Eclipse has a variable transmittance coating to meet the requirement for a single day/night visor for aircrews. The Eclipse Electrochromic Device (EclipseECD) is well suited for light modulation applications. The EclipseECD modulates transmitted light intensity over a broad range (80% to 20% transmission) by changing optical density under an applied electric field (1.5V). This process is reversed ...
