This proposal addresses the exploratory development and evaluation of novel thin film and/or monolithic detonators as diverters for guided spinning projectile use. A number of such detonators comprise a diverter technology termed RMDM, (for Ring Matrix Diverter Module) which, along with the SSPG (for Small Spinning Projectile Guidance) seeker, forms the basis for inexpensive miniature guided proje ...

We offer an approach to a multiple-order-of-magnitude processing speed/efficiency improvement in vector quantization (VQ) data/image compression, automatic target recognition/classification, and time signal/signature classification. We base our approach on an algorithmic breakthrough, the TABULAR NEAREST-NEIGHBOR ENCODER (TNE), which we discovered and partially developed last year. This algorithm ...

SiC has exceptionally high thermal conductivity and low linear expansion coefficient to resist thermal distortion, high elastic modulus to resist pressure and bowing distortion. It is lightweight and wear resistant. It also has excellent corrosion resistance and outstanding load bearing characteristics at elevated temperatures. Its hardness is only surpassed by diamond, CBN and boron carbide. As ...

This Small Business Innovative Research Phase I project will focus on the development of a compact, rugged, low-maintenance, cost-effective, all Solid-State Raman Image Amplifier (SSRIA) capable of amplifying low-level LIDAR images and producing gated images with potential gate times of less than a nanosecond. The innovative technology to be implemented is based on a solid-state stimulated Raman s ...

Unexpected coupling between nuclear reaction cross sections and the solid state of metal deuterides has been demonstrated in layered Pd-PdO deuterided structures. As a result, high rates of charged particle and neutron measurements have been observed through a reaction initiated by altering the chemical state of the system. Moreover, the system acts as an amplifier of fast neutrons, with a 200-to- ...

Passive broadband limiter with high response speed is a promising device used to protect optical sensor against determined attack. Lam Optics, Inc. (LOI) proposes to investigate the development of a novel optical limiter using commercially available materials. The optical limiter operates on the following principles. These are beam self-defocusing and total internal reflection induced by absorptio ...

THE PROPOSED PROGRAM USES POLARIZATION REVERSAL ON FERROELECTRIC MATERIALS THAT YIELD CURRENT DENSITIES IN THE kA/cm2 RANGE. THE FAST CHANGE IN THE POLARIZATION VECTOR WITHIN THE MATERIAL RESULTS IN A TRANSITION THAT LIBERATES THE POLARIZATION INDUCED CHARGES (4 P) RESULTING IN A CURRENT PULSE LIMITED ONLY BY THE TRANSITION TIME AND SPACE CHARGE EFFECTS. THE PROPOSED PROGRAM WILL DEVELOP THE TECHN ...

Liquid rocket engine performance can be dramatically improved by increasing the wall temperatures for operation concurrent with a reduction in the component weight. The bipropellant fuel combustion temperatures are between 3000 "approx" 3500 C. The conventional thrusters and exit nozzles made of niobium alloys have a maximum operating temperature limit of 1600 C. A regenerative cooling technolo ...

Essential Research, Inc. proposed to develop an ultra-high efficiency, dislocation-free, monolithic two-terminal, two-junction InGaP/InGaAs on Ge solar cells for space applications. The energy bandgap (Eg) values for the top and bottom cells will be 1.7 eV and 1.1 eV, respectively. These bandgaps are theoretically optimal for a two-junction tandem cell configuration. This solar cell will have a pr ...
