We propose a unique GaN-Al(sub x)Ga(sub 1-x)N heterojunction based CCD for imaging in the ultraviolet (wavelengths less than 365 nm). Our proposed device will be solid state, TTL compatible and in it's final configuration solar blind. The Phase I program is aimed at establishing the technical feasibility of our device concept. Our proposed CCD is in essence a GaN-AlGaN gated photoconductor with ...

An open problem confronting Uninhabited Tactical Aircraft (UTA) is the control concept for their successful operation in combat. Unlike reconnaissance UAVs, it will not be practical to operate UTAs with fully pre-programmed missions nor will it be possible to continuosly fly with them from remote cockpits. A new control paradigm is needed. One that supports a full range of intervention from dir ...

This proposal describes new low cost, low risk semiconductor-based approaches to fuze trigger circuit technology. These innovative approaches build on the promising new technology platform developed by ARIA as part of earlier SBIR research. ARIA's technology platform, initially developed for driving extremely high speed (400 picosecond rise time), high peak current pulses (400A) through laser di ...

N/A

The development of an immersive environment to visually simplify complex situations, by minimizing distractions and maximizing information presented to the user, promises to re-define the current man-machine computer interface. This proposal will define a prototype for a seated immersive interface to transport the user around in an artificial/virtual environment. The environment will surround th ...

The project objective are to develop a new software method for the dynamic analysis of aircraft and to prove the potential of unique high angle of attack Leading Edge Vortex Control (LEVC) devices. The software method will be an upgrade of a current computer code. The upgrade will include the effects of hysteresis during dynamic stall. New methods recently published employing state-spac ...

N/A

This effort will address five problems in the process design of heterojunction bipolar transistors (HBTs) and high electron mobility transistors (HEMTs): (1) HEMT thermal impedances will be measured using a novel method and will be compared with finite-element simulations to provide more accurate values for computer-aided design programs. (2) The role of the spacer layer in HEMT performance and ...

Infrared Solutions, Inc. (ISI), with assistance from its subcontractor, the Honeywell Technology Center (HTC), proposes a Phase I contract to design an uncooled bolometer staring infrared array and camera suitable for use in a home security system. The array will be a low-cost, reduced-complexity version of Honeywell's well-known silicon microbolometer array which was developed under the HIDAD pr ...

IN THE PATH OF A ROCKET MOTOR EXHAUST, VARIOUS SOLID SURFACES SUCH AS THE ROCKET NOZZLE, JET VANES, AND TURBINE BLADES ARE SUBJECTED TO VERY HIGH TEMPERATURES AND LARGE HEAT FLUXES. OFTEN SERIOUS EROSION OF THESE SURFACES OCCURS WITHIN A FEW SECONDS. THE FLOW IN THE EXHAUST PLUME IS NOT ONLY SUPERSONIC AND VERY HOT BUT USUALLY CONTAINS ALUMINUM PARTICLES, WHICH CHANGE THE PROPERTIES OF THE PLUME G ...
