The objective of this program is to characterize the upper atmosphere electrical environment so that the effects of this environment on high altitude airships (HAA) and other platforms intending to operate in this environment can be determined, and protection methods developed. This includes transient luminous events (TLEs), such as red sprites and blue jets and their associated electrical propert ...

Highly energetic chemical processes play a central role in many military and commercial applications. For example, spectral emissions from missile plumes, arising from high-velocity chemical interactions of exhaust gases with the atmosphere, are used to detect, track, and identify threat targets. Detailed, quantitative knowledge of the energy-dependent chemical reaction cross sections and rates i ...

High-fidelity missile plume flowfield simulations of MDA interest require use of detailed chemical kinetic mechanisms, which significantly improve IR/UV/RCS/visible signature prediction but entail long solution runtimes for completion. These long runtimes result from the required iterative solution of large systems of stiff, non-linear chemical source terms at each CFD mesh point; this curtails t ...

Radiation Hardened Multi-color infrared (IR) focal planes are required for MDA/SMDC systems applications . Key to meeting these system requirements is to develop multi-color radiation hardened HgCdTe focal plane arrays for LWIR band ( 7-14 microns) and VLWIR band with wavelength of greater than 14 microns with high pixel uniformity, reduced readout noise, improved resolution, and higher temperatur ...

MDA is developing materials for several applications including hypersonic missiles, ma-neuvering reentry vehicles, advanced solid rocket motors, and divert and attitude control sys-tems. All of these applications employ components that must operate at temperatures above 3000°F. Viable structural materials for these conditions can be loosely grouped as graphite, ce-ramics (e.g. oxides, carbides) ...

We propose to study the development of a dedicated neutron source for Single Event Effects (SEE)to be collocated and intregrated with an existing neutron source (LENS)at the Indiana University Cyclotron Facility (IUCF). The study will maximize use of existing facilities to maximize the cost/benefit for the SEE neutron source.

This program will develop an appliqu"¦ based on a multi-layer film which will be conductive as well as possessing good optical properties (low ¦A, high ¦Å). The film will be designed to be highly resistant to the space environment. This white, conductive appliqu"¦ will be easily applied to most external areas of the spacecraft. The appliqu"¦ is expected to have multiple layers, each indiv ...

Programs such as Airborne Laser and Space-Based Laser are in need of highly mass efficient structural materials to achieve system performance targets. This naturally leads to graphite fiber reinforced polymers for many system components. For someapplications, such as cryogen storage vessels, these materials are subject to micro cracking under little or no structural loading. New materials with ...
