Acroamatics, Inc. proposed to perform research to develop a method permitting the telemetric transmission of avionics bus data from an air vehicle under test to a remote receiving station using a narrower radio frequency (rf) bandwidth than presently required. Increasing use of digital avionics in aircraft and reduced availability of rf spectrum make this an important topic of development. The s ...

An innovative Microwave-Powered Monopropellant Hydrogen Plasma Ignition System for hydrogen fueled rocket engines, which develops a plasma using only the hydrogen feed gas to the igniter, is proposed to replace current enhanced spark or torch igniters which require the use of a pre-mixed quantity of hydrogen and oxidizer. The ignition system employs air plasma generation technology developed for ...

Advanced aircraft are required to perform large amplitude maneuvers and high precision tracking in the presence of disturbances, uncertainties, nonlinearities, and component faults. The recently emerging nonlinear H control approach is proposed here to meet the ever stringent mission requirements on advanced aircraft. Our approach features the following innovations: 1) by incorporatin ...

Theoretical chemistry techniques used to provide fundamental understanding of the molecular requirements for achieving conductive and nonlinear optical properties in polymeric materials are implemented in large scale parallel software enabling investigations on realistic models. The algorithms are based on techniques for simultaneous optimization of the electronic and nuclear coordinates. Linear r ...

A methodology is proposed for introducing the capability of modeling active MMICs into the industry-standard three dimensional electromagnetic field simulator High Frequency Structure Simulator (HFSS) and Maxwell SI Eminence. The first objective of the proposed work is to evaluate the existing capabilities of HFSS/Eminence for characterizing the passive three dimensional interconnect problems as ...

Currently, most antenna array designs are mechanically steered. However, as demand for higher performance antennas increases, an electronic replacement for the mechanical system becomes necessary. An alternative that may prove to be more cost effective is to use ferrite patch antennas as the elements in the array. The antenna's radiation characteristics are controlled by the direction and magni ...

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 ...

Apollo Enterprise proposes to develop a highly sensitive, remotely deployable sensor system for hydrocarbon detection in waste water. The novel device is designed to monitor the hydrocarbons in waste water in real time and will serve as a tool to minimize the release of contaminated water into local waste-water systems. Current monitoring is performed by visual inspection based on the presence of ...
