Many large-scale numerical simulations can be broken down into common mathematical routines. While the applications may differ, they often need to perform standard functions such as system solves, Fourier transforms, or eigenvalue calculations. Consequently, producing fast, efficient implementations of these methods will benefit a broad range of Air Force applications. Graphics Processing Units (G ...

In this proposal, AlphaSense, Inc. and the Center for Non-destructive Evaluations at Iowa State University detail the development of a compact, low cost handheld sensor for non-destructive material case depth verification. The key innovations of this proposal include the following: a) case depth evaluations based on electromagnetic property measurements, b) a model based alternating current potent ...

The global war on terror has dramatically changed the environment in which today's warfighter operates. Many of the locations in theater require moving troops and equipment into areas with unimproved landing zones. Loss of situational awareness in degraded visual environments is one of the largest threats to rotary wing aircraft operating in these areas. Phase Sensitive Innovations has built a pas ...

The maturation of Titanium Matrix Composite into an affordable material system with production experience on the F-16 opens up a wide series of opportunities for improved propulsion performance. This SBIR builds on the baseline TMC demonstrations being conducted by FMW and ATK and extends them to advanced systems. The use of configured residual stress states and enhanced Titanium matrix systems ...

The future propulsion requirements of the USAF will require substantial performance improvements, especially stage mass fraction as defined by the Phase III IHPRPT goals. The development and transition to production of titanium matrix composites (TMC) offer the potential of significant mass fraction gains for liquid engines. This program proposes the substitution of TMC into the impeller, which ...

Under the DARPA sponsored Naval Advanced Amorphous Coating (NAAC) program, a novel, thermal sprayed amorphous metal coating has been developed. Such a coating has demonstrated superior mechanical and corrosion resistance properties. Although the coating is designed to be life-of-ship, the application and operational conditions may compromise the integrity of the coating. For example, the applicati ...

Thermal barrier coatings have been widely used to provide thermal protection to superalloy components in gas turbine engines. After certain amount of service time, the coating experiences a reduction in thickness by processes such as wear, erosion and foreign/domestic object damage. When the thickness decreases below a critical value, the thermal barrier effect provided by the coating is no longer ...

In phase I, we have proven the feasibility of using the microwave cavity perturbation technique to detect and quantify DoS in marine aluminum alloys. We implemented an alpha version sensor prototype, characterized and validated its performance using ASTM G67 method. We also identified methods to further enhance the sensor sensitivity, so that DoS in the low (a few mg/cm2) to moderate range can be ...
