Despite the rapid commercialization of additive manufacturing technology such as selective laser melting, SLM, there are gaps in process modeling and material property prediction that contribute to slow and costly process qualification and product certification. To address these gaps, CFDRC and our partner Dr. Kevin Chou, University of Alabama, will develop multiple computationally efficient, high ...

The liberation of particles induced by rocket plume flow from spacecraft landing on unprepared regolith of the Moon, Mars, and other destinations poses high mission risks for robotic and human exploration activities. This process occurs in a combination of "extreme environments" that combine low gravity, little or no atmosphere, rocket exhaust gas flow that is supersonic and partially rarefied, an ...

Launch vehicles experience extreme acoustic loads during liftoff driven by the interaction of rocket plumes and plume-generated acoustic waves with ground structures. Currently employed predictive capabilities are too dissipative to accurately resolve the propagation of waves throughout the launch environment. Higher fidelity non-dissipative analysis tools are critically needed to design mitigatio ...

Advances in structured heterogeneity together with nanomaterials tailoring has made it possible to create thermoelectrics using high temperature, polymer composites. While such thermoelectrics do not have the capability to approach the efficiency of top performing ceramic modules such as BiTe, they do provide two unique aspects of use in energy scavenging: the ability to conform to irregular large ...

The objective of this proposal is to integrate three unique energy harvesting technologies utilizing our existing research strengths that will be of interest and utility to NASA applications and environmental conditions. By developing multiple technologies, NASA will be able to harvest energy from multiple waste energy sources, namely environmental vibrations, thermal energy, and solar flux. These ...

GTL has been developing three transformational technologies that have the capability to disrupt the traditional launch vehicle paradigm. BHL composite cryotank technology provides a four times improvement over large Al-Li tanks, offering a 6 percentage point improvement in stage PMF. Superior Stability Engine is an innovative liquid rocket engine configured to maximize combustion stability margi ...

Advanced turbomachinery components play a critical role in launch vehicle and spacecraft liquid rocket propulsion systems. To achieve desired efficiencies, extremely tight tolerances are often imposed between inducer blades and shrouds or other system components which sets up strong interactions that influence both the aerodynamics and the structural performance of blades and vanes. These transien ...

Chemical contamination of spacecraft components as well as thermal and force loading from firing liquid propellant thrusters are critical concerns for in-space propulsion applications. Gas molecular contamination and liquid droplet deposition due to incomplete combustion threaten to damage surface materials, sensitive instruments and optical sensors, and poses major risks for mission success. Liqu ...

NASA recognizes the importance of conservation, smart utilization and reuse of resources for their deep space missions to address the need for regeneration of air, water and waste with highly reliable systems to reduce mission payload. Additionally, energy for life support and other systems needs to be obtained from renewable energy sources or waste streams. In order to address NASA's requirements ...

Newly developed phase-engineered and low dimensional materials have opened the door to the design of materials structures that exhibit extremely efficient ionic transport. Recently, a new type of electro-filtration system designed to convert thermal power into purified water from salt water (or other ionic pollutants) has been demonstrated in the lab. The system is based on a bi-phasic nanoplate ...
