The Navy seeks to develop new, innovative motor/generator technologies that can effectively operate at speeds up to 1,000 kRPM at power densities of 40 kW/kg (excluding heat exchanger) with an overall system efficiency of 95% or better. Such a motor/generator will have a wide range of applications, i.e. it can be used as the core building block of a very lightweight electrical energy storage syste ...

The performance of a composite material is heavily influenced by the strength and toughness of the interlaminar region, which is the resin rich area between the plies of a fiber reinforced composite.  The interlaminar region generally provides a direct path for crack propagation since no continuous reinforcement is present and is often the cause of failure in materials subjected to cyclic loadin ...

Naval aircraft components are routinely made of 7000 series aluminum alloys due to their strength, weight and fatigue properties. Present Additive Manufacturing (AM) processes fall short of producing 7000 series Al alloys successfully due to lack of porosity, and thermal and composition control. In-situ methods implemented to date largely only yield information about the component surface and othe ...

OKSI and Northwestern University propose to develop a single-image super-resolution (SR) methodology for mid-wave infrared (MWIR) imagery that combines learning-based and regularization-based approaches to produce extreme enhancement of low-resolution images. We will also develop a detector-limited imaging system specifically designed to be used with the SR methodology for which even higher levels ...

The Alpha STAR Corporation and the University of Akron STTR Phase II proposal will establish ASTM standards test methods to determine relevant ceramics matrix composites (CMC) delamination crack growth resistance (CGR) material properties (Mode I & Mode II)under service load temperature conditions. Phase Ii will expand on Phase I results, conclusions & recommendations. Emphasis will be on testing ...

Air-Borne Sense and Avoid (ABSAA) cooperative sensors like TCAS and ADS-B are non-developmental off-the-shelf items and as such their employment should be optimized to maximize their effect on levels of safety. The radar subsystem is a new construct whose role and employment has not been previously defined. In addition, the cost of the radar development and production costs are high and dependent ...

MK-41 VLS exhaust paths are lined with ablative insulation that chars and ablates with each missile firing. There is no way to inspect, in-situ, chemical and physical changes to the ablatives. Such measurements are complicated because ablative materials: vary with location, are low density, and degrade non-linearly with firings.Failure of VLS insulation is not an option – but the usage life of t ...

Thousands of years of evolution have produced the human vision system that computers cannot replicate well. Humans are still unsurpassed in their ability to search for objects in visual scenes. To successfully detect objects in cluttered scenes, the human brain is thought to rely on multiple factors: prior probabilities of object occurrence, global scene statistics and object co-occurrence. Machin ...

ATA Engineering has developed a wavelet-based damage squeezing methodology for generating optimally compressed fatigue test signals that produce an equivalent amount of fatigue damage in a predictably reduced amount of time compared to the baseline (uncompressed) signals. Fatigue-critical signal characteristics (e.g., magnitude, phase, frequency, and sequencing relationships) are identified in the ...

Altex Technologies Corporation, a small business, and Pennsylvania State University, a research institution, have teamed up to develop the innovative Person Portable JP-8 Fueled Fuel Cell Power Generator (PJF-Gen). The 500-1000 watts system will be lightweight, the size of a lunch box, will reliably operate on JP-8 and start fast, thereby meeting all Navy requirements. This is achieved by using ...
