ABSTRACT: ORBITEC will develop a new diagnostic to acquire simultaneous planes of velocity and temperature data at very high repetition rates. This diagnostic relies on a novel pulse burst laser system, a phosphor thermometry technique, and the mature PIV method. The work plan will involve developing and testing the laser, refining the integrated technique, and demonstrating it in a supersonic ...

ABSTRACT: A smaller transmitter package operating in C-band with greater power efficiency will pave the way for newer, compact weapons to utilize the expanded frequency range at C band. BENEFIT: Reduced payload weight, giving off less heat, with longer battery life.

ABSTRACT: This Phase II proposal will capitalize on the success of Phase I to further develop stable and optically efficient fluorescent particles that absorb and emit light in the infrared part of the spectrum and lack any visible light emissions. The specific goals of Phase II will be to further research infrared nanoparticles to increase their brightness with an emphasis on production scalabi ...

A novel and new method of measuring the far-field noise of a helicopter is proposed by the Delta Group International/University of Maryland team that uses a hot-air-balloon as the measurement platform. The method meets the Army STTR objectives of being capable of measuring helicopter noise above and near the tip-path-plane of the helicopter without measurable ground reflections. The new method i ...

ABSTRACT: UltraHiNet, LLC (UHN) proposes to develop a prototype next generation tracking architecture which exploits wide area motion imagery (WAMI) systems and leverages projected heterogeneous high performance computing (HPC) architectures for on-board and ground-based processing of vehicle and dismount targets for urban surveillance. Our research team will focus on the following goals: 1. Dev ...

Understanding imagery from unmanned automated systems in a timely fashion requires support systems for end users that can filter and preprocess massive data via complex vision and understanding. A new computer system that mimics both the bottom-up biological and top-down cognitive processes of the human visual system will provide breakthrough decision support for immediate imagery analysis. We pro ...

ABSTRACT: The ability to obtain time-resolved, direct wall shear stress measurement is an important asset to aerodynamic research, flow control and to enhance the fundamental understanding of the turbulent boundary layer. Due to a lack of reliable and affordable skin friction sensors, existing indirect methods are used to measure wall shear stress but their usefulness is limited since prior kno ...

ABSTRACT: Most cross-domain information flows require some human intervention to ensure that the requirements for releasability are met. Such intervention is expensive and slow, and can form a bottleneck in operations. Unfortunately, fully automated sharing of information across security domain boundaries is also fraught with difficulties due to problems with identifying releasable information, a ...

ABSTRACT: Phosphor materials are currently being utilized in a wide variety of applications. The requirements for phosphors have become more and more stringent with smaller and smaller particles being required. In the Phase I program UES Inc. in collaboration with Penn State University has demonstrated the feasibility of a few approaches for high rate production of high efficiency IR to IR up-con ...

This Phase II STTR program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPam1/2) ultra-high temperature HfC-based composites (UHTC) with an outstanding oxidation resistance for advanced rocket nozzle throat components. UES will apply a novel"Top Down"approach to control the microstructures of the composites. This approach will produce a very unique grain structur ...
