Many existing or proposed NASA small propulsion systems and advanced scientific instruments will require high voltages at medium to high power levels to function. Such space power supplies are generally bulky and lossy and, as missions increasingly migrate to ever smaller platforms, there will be an increasing need to substantially reduce the size/weight costs of providing such on-board power acce ...

70883 Future high field (15T+) dipole magnets, needed for high energy physics experiments, will require higher performance superconductors with long piece lengths to reduce the cost of these conductors. Nb3Al superconductors can fulfill this need, and this project will configure this wire as a practical HEP conductor with a high filament count. The long piece lengths will be addressed by e ...

This program is directed toward synthesis of two closely related classes of new lithium ion conducting polymer electrolytes which hold promise of achieving both higher ionic conductivity and improved elastomeric properties over current state-of-the-art polymer electrolytes. Approaches to be used for synthesis of these two materials will be based upon, (i) the modification of polycarbonate hosts by ...

The objective of the proposed effort is to examine the feasibility of applying advanced laser architectures towards the ultimate development and delivery of a high energy and repetition rate non-Chirped Pulsed Amplified (non-CPA), Ultra-Short Pulse Laser (USPL) prototype system. The proposed conceptual design is capable of producing sub- 500 fs pulses, > 10 mJ/pulse, and > 1 kHz repetition rates a ...

NextGen Aeronautics, Inc., in collaboration with Prof. Steven Son’s group at Purdue University and Dr. Darren Naud, is proposing to design nanoparticle enhanced high energy density propellants using theoretical and simulation methods, and verify the design by small-scale laboratory production and testing. We will use molecular dynamics and implement novel dissipative particle dynamics metho ...

Under this Phase II SBIR program NextGen Aeronautics, Inc. in collaboration with Purdue University is proposing to develop and test nanoparticle enhanced high energy density propellants for guns. Our approach consists of a combination of experimental investigations and computational modeling/simulations. In Phase I of the proposed research, we have articulated manufacturing steps for mixing nanopa ...

Future NASA science missions require rechargeable batteries that can operate over a wide temperature range, including the ability to charge and discharge at very low temperature conditions. For example, Mars and small body surface mission concepts which include robotic landers, rovers, and aerial vehicles, require rechargeable batteries capable of operating down to nbsp;nbsp;-40deg;C conditions. S ...

The present lithium-ion battery technology needs further improvement with respect to specific energy (Wh/kg) and energy density (Wh/l) for military, aerospace, and transportation applications. The improvement in specific energy and energy density can be achieved by choosing (i) an electrochemical couple having high specific capacity of individual electrode materials and/or (ii) an electrochemical ...
