ABSTRACT: Improvements such as increased array size and better non-uniformity correction have been made to resistive emitter arrays fabricated on silicon (Si). There exist additonal wavelengths of interest whose emitter devices require fabrication in other materials, such as gallium arsenide (GaAs). For both Si and GaAs substrate materials, attempts to"tile"small arrays into larger ones for reaso ...

The goal of this SBIR is the enhancement of the current state-of-the-art combustion instability analysis tools.  The planned enhancement is focused on capturing the effects of injection element distribution and the inclusion of substantial film cooling and diluent injection.  These characteristics are extremely important in the design of high-pressure oxygen rich staged combustion (ORSC) engines ...

ABSTRACT: Desired tactical requirements for unmanned aerial systems (UASs) exceed current capabilities for performance, reliability, maintainability, cost and supportability. Mission requirements such as extended endurance, increased power for auxiliary/sensor systems, and low altitude, low speed maneuverability are becoming paramount, specifically, in the 10,000 lb class of vehicles. These desi ...

ABSTRACT: Modern military aircraft are encountering major thermal obstacles as a result of significant increases in on-board heat generation combined with a reduced ability to transfer heat to the ambient environment. Adaptive power and thermal management systems (APTMS) are being studied in great detail in order to mitigate these thermal restrictions, but complexity of such systems necessitates ...

This Phase I SBIR project will evaluate the feasibility of utilizing low cost and high accuracy local position sensors and transmitters to autonomously estimate Mid-chord offset in rails. The two innovative parts of the proposed system are (1) a set of miniature and highly accurate local position sensors and transmitters for estimating the absolute positions of the mid point and end points of a 62 ...

The Phase I SBIR project will evaluate the feasibility of utilizing a low cost sensor to obtain rail temperatures from a moving train. The two innovative parts of the proposed sensor are (1) a rugged four wavelenght high frequency sensor that accurately measures the natural radiation emitted by the rails, and (2) an advanced algorithm that provides a emissivity compensated temperature from these ...

ABSTRACT: Digital Solid State Propulsion is proposing to develop a Divert and Attitude Control System (DACS) for tactical air superiority missiles, using proprietary Electric Solid Propellants (ESPs). Unlike conventional propellants, ESPs can be ignited with electric power applied through inert electrodes within the propellant grain itself, while also maintaining a higher level of insensitivity. ...

ABSTRACT: The Air Force is seeking a compact, high torque, rotary EMA technology capable of controlling flight control surfaces directly at the hinge line in the next generation of thin-wing aircraft. Proposed for this application is an advanced EMA technology based on an axial flux, permanent-magnet machine structure. The unique shape of this device enables efficient integration into the wing ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...

This Phase I effort will show that cooperative receiving devices can determine their locations with good accuracy using only signals of opportunity without a global positioning system (GPS). Using emitter of known location, algorithms for calculating receiver location from cooperative signal processing routines will be developed. The focus of the Phase I effort will be on high-power terrestrial br ...
