In this program, DSR proposes to develop test equipment that can be used by the Air Force to begin investigating inert and live explosive material properties under different pressure and temperature environments. Strain-rate levels will be adjustable with this equipment and will vary between 10-5-10-2 s-1 dependent upon the stiffness and strength of the test material. When completed, 25.4-mm-dia ...

In Phase-I of this work, a steady state model incorporating the most important nonlinear effects was successfully developed to analyze passive phasing of fiber amplifier arrays. This work showed a technique of reverse pumping to mitigate Four-Wave Mixing (FWM) and Cross-Phase Modulation (XPM) in fiber amplifiers. In Phase II we propose to extend the modeling developed in Phase-I to include time-de ...

This Phase II program builds upon the success of the Phase I conceptual design effort, in which novel architectures and techniques were developed in order to create a wide-band hyperspectral fundus imager. This device allows hyperspectral retinal images to be collected over the entire transmission range of the eye, an unprecedented capability. The device is designed to allow an adaptive optics mod ...

Our recent developmental efforts have successfully produced the design for a chip slapper with a reduction in the average size (miniaturization), weight and cost of these particular chip slappers. The processes that we have established in the production of this chip slapper have reduced the number of assembly stages for this particular assembly configuration and/or application. Production of this ...

Nonlinear transmission lines offer new vistas in the generation of high power microwave wave (HPM) signals. All electromagnetic sources use an active medium to convert electrical energy to high frequency waves and ultra-wide band signals that can perform useful work. Traditional methods rely on electron beams for the active medium. Nonlinear transmission lines use nonlinear circuit elements to ...

Aerosol Jet printing is proposed as a method for printing large area, CNT-based transistor arrays on flexible substrate. The teaming relationship combines expertise in high resolution printing along with device and materials expertise. All semiconductor, dielectric, and conductive materials comprising the TFTs will be solution processed and printed with a single machine. This will lead to a cos ...

Our proposed approach is to generate a physics- and data-based characterization of the dominant spatio-temporal modes of the phase-perturbation due to the near-field turbulent environment of an aircraft-mounted turret-based system. This modal description will depend on view angle, and will be synchronized in flight, prior to engagement. The modes will represent the necessary corrections to a def ...

High energy density capacitors are required for practical implementation of GW-class pulse power loads. In response to this need, TPL has established unique dielectric and capacitor capabilities. Revolutionary materials, designs and manufacturing process have been developed for power sources that have potential for an order of magnitude reduction in mass and volume relative to current commercial ...

Thermally stable, high frequency capacitors are necessary for development of more compact, high power electronics for use in high performance weapons systems. Mechanically and thermally robust capacitors are needed to increase the temperature range and reduce thermal management issues in compact aerospace power conditioning applications. Capacitors can occupy up to 30 percent of the volume in po ...

Vibrant proposes to use Process Compensated Resonance Testing (PCRT) technology to detect defects in chrome and high-velocity oxygenated fuel (HVOF) coatings and high-strength steel (HSS) substrates of landing gear (LG) components. Currently, fluorescent penetrant inspection (FPI) and ferromagnetic particle inspection (FMPI) are used to inspect HVOF-coated parts. While good at finding surface crac ...
