AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction monolithic tandem solar cell two terminal design of (AlxGa1-x)0.51In0.49P/GaAs yielding a best case pred ...

ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH PERFORMANCE, ULTRA-THIN ELECTROSTATICALLY BONDED GaAs SOLAR CELL WITH COPLANAR BACK CONTACTS. THE INNOVATIVE DESIGN INCORPORATES LIGHT TRAPPING, ADHESIVELESS COVER SLIDE BONDING, AND ELIMINATES GRID SHADING. THIS NOVEL DEVICE WILL EXHIBIT INCREASED EFFICIENCY AND SPECIFIC POWER DUE TO THE HIGHER OPEN CIRCUIT VOLTAGE AND SHORT CIRCUIT CURRENT OBTAI ...

Intense dynamic and thermal loads will occur during stage-separation events that are of major concern from both operational and safety viewpoints. The insensitive-munitions (IM) stimuli and thermal/dynamic response associated with such events has received very little attention, yet this is of major concern for the KEI vehicle undergoing Stage 1 to Stage 2 separation. The KEI event is at lower alti ...

Propulsion systems may perform a variety of maneuvers during the ascent phase of flight that can impact the performance of an interceptor or other parts of an MDA system designed to perform threat detection, discrimination, and tracking. Our Phase I effort focuses on building on extending existing plume signature software. A main technical objective is to establish the various components and app ...

Our Phase I research involved the development of an innovative sensor scheduling algorithm in support of Ballistic Missile Defense. This algorithm schedules multiple diverse and distributed sensors to perform time-critical tasks relating to multiple moving targets; specifically, to detect, classify, localize, track, support the interception of, and conduct BDA for ballistic missiles throughout t ...

The project objective is to develop a tracking algorithm that will fuse detections and tracks provided by a network of radar sensors with detections and tracks provided by a network of electro-optical (EO) sensors into multi-system tracks. The intent is to thereby achieve increased state estimation and classification accuracy in tracking ballistic missiles. Both target kinematic states and featur ...

MDA is currently developing advanced interceptors for its BMDS. Imaging technology is crucial to this effort for several purposes, including navigation, false-alarm/decoy identification, and estimation of position and speed of potential targets. Although high-resolution imaging systems are readily available, these require (1) power-hungry CMOS arrays (or FPAs) and (2) large-aperture optics, whic ...

The primary objective of this Phase I program will be to demonstrate a greatly improved manufacturing and production techniques for die packaging of anti-tamper capabilities. We aim to show through manufacture engineering research, software development and hardware prototypes, a new low-cost technique for multi-threat capable Anti-Tamper (AT) device manufacture and AT software-based multi-threat ...

This proposal describes the application of a mature nanotechnology-based crack arrest / structural repair technology as a novel crack arrestor tool for high-strength pipelines. The crack arrestor would comprise a thin layer or sleeve of electrodeposited nanocrystalline material applied to the outside of the pipe either in the coating mill during fabrication or in-field during or following constru ...
