During aircraft turbine engine operation, augmentor (afterburner) operation is often associated with combustion instabilities (oscillations) that can be potentially detrimental to the turbine engine if the resonant amplitude levels are excessive.Oscillation in the frequency range of 50-100 Hz is commonly called

This subtopic solicited Phase I R&D for an advanced Fourier transform infrared (FT-IR) system that would provide fast-scanning high resolution (3 scans/sec at 1cm-1 resolution), low noise, mid-infrared measurements for characterization of spray flames. In Phase I, Advanced Fuel Research, Inc. (AFR) demonstrated FT-IR emission/transmission (E/T) measurements from the NIST spray combustion faci ...

Rain and dust erosions on aircraft forward facing surfaces such as leading edges, engine inlets, nose radomes, propeller blades, and antennas are serious problems. Due to increasing optical missile threats more low gloss rain erosion coatings are beingused. Current commercial lusterless gray rain erosion coating failed the rain test within 36 minutes when tested at 500mph under 1

Oceanit has successfully shown in Phase I that highly accurate (sub-arcsecond) observations are obtainable utilizing a relatively low-cost COTS system. These highly accurate angular observations can be introduced into the orbit determination process as asupplement to high-quality range data. These improved angular observations help resolve the geometric ambiguity of range-only orbit determinatio ...

The double-clad multicore fiber laser has proven to be the most efficient, optically-pumped laser. In Phase I, we have demonstated that phase-locking occurs spontaneously among a group of closely packed single mode fiber lasers configured isometrically ina common cladding. This result suggests that, by using our unique power combining technique developed at PC Photonics Corporation, high power o ...

The Air Force is in need of a system to measure stray laser energy during the open-air test-range firing of high-energy laser weapons such as the Airborne Laser. In Phase I, a laboratory-scale system composed of four hemispherical-imaging laser-scattering detectors was constructed to monitor light scattered from stray laser energy during simulated laser weapon engagements. It was demonstrated th ...

In Phase I, Ambient Micro successfully demonstrated the capability of its Multi-Source Ambient Power Supply module to simultaneously harvest and store energy from multiple ambient sources to extend the operating life of MEMS Vehicle Health Monitoring sensors for UAV-mounted sensor systems. As the U.S. Air Force increasingly evolves UAV mission roles to support persistent surveillance, persistent s ...

The project aims to further develop the AeroLensCraft for high-altitude air platform, and to engage in hardware validation of key innovations and enabling technologies : the unique shape, with TVM, and the unique energy harvesting, storage and recovery system combined with the buoyancy system.

An automatic software tool for damage tolerance assessment and residual strength prediction of composite structures based on the extended finite element (XFEM) will be developed. This tool will for the first time be able to model arbitrary 2D/3D delamination crack growth without remeshing. The automated tool will be integrated with the ABAQUS implicit solver via its user-defined subroutines. GEM h ...

The Phase I effort will develop specifications for applying a gaming environment to the training, rehearsing, and exercising of Offensive and Defensive Counterspace (OCS/DCS) Operations. Our team will innovatively apply our state-of-the-art commercial gaming engine, coupled with advanced human engineering, human performance, and training system development expertise to craft a set of specification ...
