Applied Radar proposes to develop a high-gain low cost, size, power and weight (low-CSWAP) tactical common data link (TCDL) antenna for the Firescout and Predator UAVs. The improved TCDL antenna will support 6 or more nodes of high-gain full-duplex communication at 21.42 MBPS in a star network configuration with 360 degree coverage out to 110 nm slant range. In Phase 1, we will design, fabricate a ...

Spectral Energies, LLC and The Ohio State University proposes a comprehensive research effort to advance the state-of-the-art in seamless computation of the interior of a nozzle in high performance turbine exhaust and downstream plume aerodynamics. The focus is on higher-fidelity methods using robust, efficient and scalable high-order accurate implicit schemes couched in a Large-Eddy Simulation (L ...

Catapult shuttle wheel bearing loading is a function of the aircraft take-off weight and the acceleration of the catapult. The resultant load on the bearings of the existing catapult has significantly changed from the time the subject bearings were selected in 1980. If the projected aircraft take-off weight is 100,000 lbs., the bearing life will be reduced by approximately 94%. The Phase I objecti ...

As aircraft technology continues to evolve, there becomes a need for advanced takeoff systems for aircraft carriers. Increases in aircraft weight and takeoff speed require takeoff systems with reliable components to withstand the increase in force put on the system by the advanced aircraft. In this project, Powdermet will target the improvement of wheel bearings for both steam catapult shuttles an ...

Radar sensor suites used by seekers and ISR platforms frequently must collect multiple types of radar data. In addition to moving target indication (MTI) data used for target tracking (tracking data), such systems often also collect high resolution radar information about specific targets in order to facilitate automatic target recognition (ATR) or classification (ATR data). This ATR data can incl ...

The goal of this Phase I research is to demonstrate a scaleable pulse power modulator circuit with a resistive load, meeting scaleable voltage, current and peak power requirements for high power radio frequency (HPRF) source. Gallium Arsenide (GaAs) based high gain Photoconductive Semiconductor Switches (PCSS) will be used for this demonstration. The Phase I demonstration will be limited to 10-100 ...

The opportunity presented under this program is to develop a next-generation, self-sealing technology that can impart self-sealing capability to the most vulnerable areas of integral aircraft fuel tanks. Targeted application of the self-sealing materials will reduce the weight and fuel-volume penalty associated with conventional fuel bladder constructions. Under the Phase I program, the technical ...

A triple pulse PIV concept and a third order correlation method was developed and demonstrated improvements in accuracy and spatial resolution of the velocity and acceleration measurements in an impinging jet flow field. A low-cost system based on overdriven LEDs, uniquely designed single frame camera for capturing the images, efficient scattering techniques, and innovative algorithms were explore ...

Double-base propellants are widely used in Navy aircraft ejection seat systems, partially because of their ability to be tailored to exhibit pronounced plateau burning. Due to degradation problems inherent with double-base propellants, it would be very beneficial to develop composite propellants with this plateau burning capability. Composite propellants typically do not chemically degrade but als ...

Particle impacts cause erosion of leading edges of the compressor airfoils as well as the side or surface of the airfoil beyond the leading edge. Although erosion resistant coatings have been developed and applied on the airfoils during the past decade or two and that have protected the side or surface of the airfoil quite satisfactorily, the erosion of the leading edge (LE) is still a serious iss ...
