The Air Force requires a system to provide over the horizon tracking to support development and test of Sea Skimming Missiles (SSM). Under this SBIR Phase I effort, Defense Research Associates, Inc.(DRA) will document system requirements, identify and assess sensor technologies capable of performing the missile tracking task, develop a system design to meet the requirements using the most promisin ...

In the naval aircraft many disparate materials are subject to galvanic corrosion, due to the marine environment. Some of these aircraft have hybrid (carbon fiber composite/aluminum) designs that exhibit accelerated corrosion damage, compared to legacy all-metal frames, due to galvanic interaction between the fastener, the composite skin, and the aluminum frame. In the Phase I SBIR program, UES Inc ...

The importance of determining crystallographic orientation information over large areas has existed within the materials science community for solutions to a variety of applications in aerospace and otherwise since the connection of MTRs and material performance was discovered, but it isn’t until recently that a feasible solution has existed. In this work, MRL will demonstrate the feasibility of ...

Rotary cannon type weapons, such as the M197 electric cannon, currently require servicing every 28 days in order to remove abrasive particulate and to relubricate the rotary drum. The Navy is currently seeking a one-time application coating, applied at the time of manufacturing or retrofit, which will at least double the time between servicing to 56 days or more. Mainstream Engineering proposes to ...

To meet the U.S. Navy need for high-dynamic-range digitizers for lidar applications, a four-input channel 17-bit dynamic-range application-specific integrated circuit (ASIC) will be developed. Each of the four high-bandwidth input channels will be configured in a fast-in/slow-out architecture, composed of a stacked 512-element switched capacitor array (SCA), capable of 2-ns time-slice sampling, an ...

With gas turbines becoming smaller and more powerful the need to accurately predict the temperature distribution of the turbine blades become crucial. The high Reynolds number (Re), poorly behave flow encountered in gas turbines makes Reynolds Averaged Navier Stokes (RANS) inaccurate and Direct Numerical Simulations (DNS) too expensive to be used as analysis tools. Large Eddy Simulation (LES) appr ...

Accurate prediction heat transfer in gas turbine components subject to cooling requires high fidelity modeling of heat transfer in the presence of high Reynolds number turbulent flow. The cooling internal to the blades results in sustained temperature gradients within the structural parts, from low temperature in the interior of the structure to increasingly higher temperature closer to the surfac ...

Spectral Energies proposes to design a multisensory diagnostic suite for measurements within elevated-pressure RDEs. This sensor will utilize tunable-laser absorption spectroscopy to measure temperature, pressure and H2O concentrations in the annulus of a rocket-RDE and background-oriented schlieren imaging system for flow density gradient imaging to provide time resolved information about the sho ...

Intelligent power distribution that changes it’s protection level to match the actual load on the circuit frees up the unused portion of power for another circuit to use it. Intelligent power distribution that also changes its over current trip point and timing to match the type of load connected enhances protection to aircraft wiring and reduces potential for nuisance tripping. Bi-directional i ...
