ABSTRACT: High-performance computing (HPC) programmers and domain experts, such as those in the Air Force's research divisions, develop solvers for a wide variety of application areas such as modeling next generation aircraft and weapons designs and advanced image processing analysis. When developing software for HPC systems, the programmer should not spend the majority of their time optimiz ...

In this SBIR program, AlphaSense, Inc. teamed with the Center for Non-destructive Evaluations at Iowa State University to develop a compact, low cost handheld sensor for non-destructive material case depth verification. In phase I, we have proven the feasibility of using an alternating current potential drop (ACPD) sensor for non-destructive measurements of case depth. Phase II will be focusing on ...

Pitting corrosion limits the lifetime and performance of turbine engine bearings and gears operated in marine environments. A number of alloys and improved treatments have been attempted to increase corrosion resistance while maintaining mechanical performance of the bearings, but few meet the expectations. Some more corrosion resistant treatments such as the low temperature expanded austenite (S- ...

Gearbox seal wear and leakage is a major source of maintenance and downtime for rotorcraft. Sentient will use our advanced tribology modeling technology to evaluate coatings and surface texturing processes for carbon face seals and provide a generalized modeling approach that can replace physical testing of seals. These models will be used to evaluate several rotorcraft seal designs proposed by ou ...

Although biodiesels have been increasingly used in automobiles, trains, commercial aircrafts and heating systems, they are not currently used in the military aircrafts and land vehicles because they typically do not meet the JP-8 performance criteria as specified by MIL-PRF-83133E. Unintentional contaminations by the biodiesels into the jet fuels can introduce adverse effects, including engine ope ...

AstroPower will develop a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51 In(0.49)P, which is lattice matched to GaAs, as the top cell in a three-junction, two-terminal tandem solar cell. This new tunable bandgap Al-Ga-In-P material is capable of current matching in a two-junction monolithic tandem solar cell two-terminal design of the Al-Ga-In-P over GaAs yielding a best case ...

AstroPower is developing a highly sensitive UV detector based on epitaxial AlGaP/GaP heterostructures, a promising new material system for ultraviolet detectors. Detecting ultraviolet light is important to spectrophotometry, astronomy, high-energy physics, medicine, UV curing, photoresist exposure, and chemical processes. The large bandgap and crystalline quality of gallium phosphide will provide ...

Next-generation high-performance computers (HPCs) are built as massively parallel systems where the parallelism exists at many levels. These systems are a collection of nodes all working together. Each node generally contains more than one processor and each processor contains multiple cores. Managing and efficiently utilizing the different parallelism in such a system is a complex task. Furth ...

ABSTRACT: Accudyne proposes a SBIR program to develop an automated material placement process for aircraft radomes and demonstrate it by forming quartz cynate ester fabric over an existing radome tool. The process employs computer simulations to model the forming process and compute a 2D fabric pattern as well as a four degrees of motion machine to form the fabric over the curved radome tool. T ...
