Reduced mass materials are critical to the success of aerospace systems. Thus, large air and space structures can benefit from lightweight composite materials. However, their adoption is impaired by the lack of a robust, cost-effective fabrication process, principally because the autoclaves used to consolidate composite laminates are so expensive for large parts. This program develops for US aeros ...

This proposal addresses the need for a new generation of water vapor DIAL transmitters. These transmitters must be UAV flight deployable and operate efficiently at a high repetition rate and low pulse energy. Aculight proposes to address this need with a compositionally tuned garnet laser that operates directly at the wavelength of interest. This quasi-four level laser material requires a very bri ...

Performance requirements for polymer matrix composites (PMCs) in aerospace and transportation applications are generally quite stringent. Among these requirements are excellent thermal stability, high strength and high toughness. Easy processing is also desirable. Electron-beam (e-beam) curing has the potential to significantly reduce the overall cost of manufacturing PMC parts for use in aerospac ...

The innovation addressed in this proposal is the development of a non-catalytic thruster for an attitude control system that employs an environmentally friendly (¿green¿) monopropellant. The thruster and tailored propellant blends developed during the course of this proposed program would eliminate the temperature-limiting catalyst beds that currently prevent the full realization of green monopr ...

For propulsion related applications, materials must be able to demonstrate excellent ablation and oxidation resistance at temperature approaching 3500?C, adequate load bearing capabilities, non-catastrophic failure modes, and ability to withstand transient thermal shock. Advanced Ceramics Research, Inc. (ACR) has developed low cost, flexible-manufacturing processes for Zr & Hf-based carbon fiber r ...

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

HIGH RANGE (200,000 G) ACCELEROMETERS ARE THE ONLY TRANSDUCERS THAT PROVIDE THE REQUIRED LONG-TERM DATA IN THE ENVIRONMENTS OF INTEREST TO THE BLAST AND SHOCK COMMUNITY. THESE GAGES HAVE A VERY LARGE DYNAMIC RANGE AND NOISE OFTEN MASKS THE LATE TIME (BUT EXTREMELY IMPORTANT) DATA. WE PROPOSE TO DEVELOP A CLOSE COUPLED LOGARITHMIC GAIN SIGNAL CONDITIONING SYSTEM THAT WILL CORRECT THE LATE TIME NOIS ...

Next generation design software will support fully associative geometric and physics-based analysis models throughout the entire product life-cycle. Most current CAD systems directly support finite element systems, but use proprietary database formats that do not promote diverse tool use and may not exist throughout the entire product life-cycle. Model sharing in common practice has been limited t ...

THE DIGITAL ACTIVE MATERIALS-PROCESSING PLATFORM EFFORT BE- ING PROPOSED HERE SEEKS TO DEVELOP AN ACTIVELY STABILIZD PLATFORM UPON WHICH MICRO-G MATERIALS PROCESSING EXPERIMENTSCAN BE PERFORMED IN SPACE. WITH THE SUC- CESSFUL COMPLETION OF THE TWO-STEP PHASE I WORKPLAN APPLIED TECHNOLOGY ASSOCIATES (ATA) HAS CLEARLY AND SUCCINTLY DEFINED THE PROBLEM OF PLATFORM ISOLATION IN SPACE AND HAS COMPLETEL ...

NASA has many needs for maintenance and repair technologies for long-duration human space missions. We propose to continue developing a compact, portable, vacuum-compatible, multi-axis Manipulator/Machining Center (M/MC) to satisfy many of NASA's needs. Our M/MC will provide complex manipulation during: layer-additive manufacturing; collection of geometric data for reverse-engineering; real-time ...
