Under the DARPA sponsored Naval Advanced Amorphous Coating (NAAC) program, a novel, thermal sprayed amorphous metal coating has been developed. Such a coating has demonstrated superior mechanical and corrosion resistance properties. Although the coating is designed to be life-of-ship, the application and operational conditions may compromise the integrity of the coating. For example, the applicati ...

In the current SBIR program, AlphaSense aimed at developing a novel, handheld, non-destructive sensor to evaluate the integrity of Naval Advanced Amorphous Coatings (NAAC) in real time. In phase I, we have proven the feasibility of using the cavity perturbation technique to detect different types of defects present in thermal-sprayed testing coupons. Specifically, we optimized the sensor probe des ...

Although biodiesels have been increasingly used in automobiles, trains, commercial aircrafts and heating systems, they are not currently used in the military aircrafts and land vehicles because they typically do not meet the JP-8 performance criteria as specified by MIL-PRF-83133E. Unintentional contaminations by the biodiesels into the jet fuels can introduce adverse effects, including engine ope ...

A liquid chemical hydride-based hydrogen storage system is proposed for high density hydrogen supply for fuel cell power generation applications. Research works performed at MER showed that certain liquid hydrides can be catalytically dehydrogenated at temperatures as low as 150¿C. The released hydrogen gas can be withdrawn from the system through a hydrogen permeable membrane to achieve comple ...

The ionosonde is a familiar instrument in radio science, with hundreds of systems around the world providing a near-continuous characterization of ionosphere configuration and dynamics. For DoD, the ionosonde is a crucial logistical asset, particularlyfor operational communications prediction. However, the majority of current ionosonde instruments suffer from hardware and operational shortcoming ...

ABSTRACT: High power nanosecond pulses provide unique capabilities for several applications relevant to defense, energy, materials science, medical applications and basic research. For the U.S. Department of Defense (DOD) new compact and portable nanosecond pulsed electric systems could provide novel solutions for directed energy weapons, efficient combustion, and aerodynamic drag reduction. To b ...

In Phase I MER demonstrated the superior performance and power-to-weight ratios of the VS-Rotary engine. In Phase II MER will team with the University of Arizona who will provide engine modeling, simulation, and analysis along with advanced precision machining and fabrication. MER will also team with NCE of Tucson to provide test and systems integration development of the engine to the applicatio ...

Military systems are traditionally produced in steel because of its excellent mechanical properties and low cost, but suffers due to its high weight and poor corrosion resistance. At ½ or less the weight of steel enables weapon systems with greater lethality, survivalability, transportability, and maneuverability and in a corrosion resistant material lowers ownership cost. Titanium metal matrix ...

Military systems are traditionally produced in steel because of excellent mechanical properties and low cost. For a lighter weight and more mobile force, all aspects of military systems are being scrutinized for possible weight reduction. Metal matrix composites with discontinuous reinforcements offer the potential for the very high strength and modulus required for targeted Army applications su ...
