The coating system currently used on U.S. Air Force and Navy aircraft is a two-coat system consisting of a chromated epoxy primer per MIL-PRF-23377 ("23377 primer") underneath a urethane topcoat per MIL-PRF-85285 ("85285 topcoat"). The development of a multi-functional coating with advanced performance properties is critical to achieving a single step corrosion inhibiting topcoat to replace the c ...

Low phase noise oscillators are core components for communications and radars. System timing jitter is fundamentally important for digital systems and phase noise is the figure of merit for RF systems. For multi-GB/s clocks, optoelectronic oscillators using optical delay for the clock period, appear to have significant advantages. The phase noise may be minimized because the delay variability li ...

This SBIR program will develop a novel software methodology for the management of gas turbine usage data in real time for accurate prediction of engine life. The approach will be flexible enough to allow for re-assessment of life consumption when subsequent knowledge provides a revised understanding of the way the damage is accrued. Phase II will further investigate potential data compression meth ...

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 ...

CompuTherm, LLC proposes to develop and experimentally validate thermodynamic databases for nickel, aluminum, and titanium based alloys. Thermodynamic databases are critically needed by the materials industry to accelerate the development of new materialsfor applications such as turbine engines. Databases greatly reduce the need for costly and time-consuming trial-and-error experiments. Unfortunat ...

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

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 ...

This effort will develop probabilistic micromechanical fatigue life modeling software . The model will integrate material characterization information with turbine engine structural design methods in order to predict the scatter in the fatigue strength ofa component subjected to high cycle fatigue (HCF). Proven feasible in Phase I, the Phase II will extend our analysis from a simple specimen to in ...
