Pursuits of highly efficient and reliable solar cells place high demands on the materials and processes used in their fabrication. For extraterrestrial cells, specific efficiency is of utmost importance, and thus the ability to reduce module weight without impacting efficiency is highly desirable. Flexible solar cells are a new direction in solar cell technology and robust substrates are required. ...

Determining the hazard classification of new propellant formulations is important for transportation safety and storage concerns. To avoid costly grain redesign and additional testing, a model that adequately predicts the shock sensitivity, including the outcome of the Naval Ordnance Laboratory Large Scale Gap Test, of modern solid propellants is required. The goals of this proposal are to develop ...

An innovative data collection and analysis approach is proposed to enable body mount magnetometers for space application. In order to achieve high accurate magnetic field measurement in space, the magnetometer has to be located in a âmagnetically cleanâ place, where the magnetic field from spacecraft is negligible. Usually, the magnetometers are placed on deployable booms, so that the field sens ...

The proposed study aims at accelerated development of Mo-Si-B-X (X=Ti, Zr, Hf, Re, Mn) alloys with an optimized balance of properties, via an approach of integrating thermodynamic modeling with experimental study.   On the basis of the Mo-Si-B-X (X=Ti, Zr, Hf) database developed in Phase I, a thermodynamic database of the Mo-Si-B-O-X (X=Ti, Zr, Hf, Re, Mn) system will be developed using the Calp ...

CompuTherm, LLC proposes a pilot project to develop a modeling tool that can be used to assess the durability of environmental barrier coatings (EBCs) for ceramic matrix composites (CMCs) under combustion environment. The modeling tool includes a thermodynamic database for the gas phase, a thermodynamic database for the silicate system (EBCs), and a computer software package that deals with thermo ...

The electron beam free form fabrication process (EBFFF) holds great promise for industry as a disruptive technology based on additive manufacturing of near net shape, high value engineered materials. The development efforts are structured to review and compare multiple process feedback systems for identifying molten pool characteristics and perform a series of open loop process parameter tests to ...

Electron Beam Free Form Fabrication has the potential to produce large titanium structures directly from 3D models eliminating or reducing the long lead times associated with designing, procuring, and implementing conventional forging tooling as well as reducing the amount of machining cost by producing near net shapes. Our proposal outlines an approach to demonstrate the use of this technology su ...

We propose a low noise amplifier for receiver front ends in wideband communication systems. The circuit will exploit wide band noise reduction techniques such as active noise cancellation. High frequency, wide bandwidth signals have several advantages ranging from high data rate communications to high resolution RADAR. However, the biggest challenge in realizing these systems is the limitations in ...

This topic is designed by the Air Force to develop a self contained sensor system that autonomously detects and tracks objects in the vicinity of a host platform and prescribe collision avoidance maneuvers as appropriate.  In this proposal the platform will be a space platform, the sensor will be dual mode and the detection range will be short as a step toward longer detection range in the future ...

TUI proposes to develop a Terminator Tape deorbit module that will utilize both aerodynamic drag enhancement and passive electrodynamic drag to enable spacecraft to comply with post-mission orbital lifetime restrictions while minimizing cost, mass, volume, and footprint impacts to the spacecraft.  At the completion of the satellites mission, this module will deploy a several-hundred meter length ...
