Cornerstone Research Group Inc. (CRG) proposes to advance fundamental material development of a high-temperature resistant, multifunctional polymer system conceived and demonstrated previously by CRG, which will provide NASA with an innovative, low-cost material for thermal protection systems. The proposed material technology results in a polymer system that transitions from a thermoplastic at tem ...

Thick, 3D woven carbon/phenolic composites offer potential improvement over legacy thermal protection systems (TPS) for re-entry vehicle heat shield applications. However due to the scale and complexity of typical re-entry vehicle structures, it is likely that multiple 3D woven panels would need to laid up to create the overall heat shield, creating a potential weak spots at the panel joints. ...

A major limiting factor in HPC growth is the requirement to parallelize codes to leverage emerging architectures, especially as single core performance has plateaued and architectures like short vector units (e.g., AVX), Intel Xeon Phi, and GPUs are embraced by hardware manufactures. The proposed SIMD/SIMT vectorization tools for emerging accelerator-based compute architectures will impact a world ...

The research objectives of this proposal are to: (1) To adapt the thermal-fluid science procedures for the prediction of weld defects to the prediction and control of surface defects and melt pool instability during the deposition of single tracks in SLM and to control the as-deposited microstructure. (2) Utilize physics-based analysis to predict variability caused in the individual SLM track cros ...

This SBIR Phase II proposal overcomes technology barriers for developing highly efficient all electric aircraft systems for the future, with limited impact to the environment. Turboelectric propulsion for aircraft applications is envisioned, and cryogenic and superconducting components are sought. In particular, low AC loss superconducting wires for the stator windings and superconducting wires wi ...

This proposal presents a hybrid metal-CMC turbine blade. A SiC/SiC CMC airfoil section will be bonded to a single crystal superalloy root section in order to mitigate risks associated with an all-CMC blade inserted in a superalloy disk. This allows current blade attachment technology (SX blade with a dovetail attachment to a slotted Ni disk) to be used with a ceramic airfoil. The bond between ...

In the combined Phase I and Phase II programs Faraday and our MIT collaborators will demonstrate the feasibility of low-cost fabrication of high-efficiency, microchannel-plate reactors for the electrocatalytic reduction of CO2 to CH4. The proposed concept is founded on FARADAYIC® Through-Mask Etching of metallic (e.g., stainless steel and titanium) substrates to form suitable microchannel electr ...

The integration of Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS) requires a robust, reliable communication link between the Unmanned Aerial Vehicle (UAV) and its operators. Constant communication is a necessity. New and innovative approaches are needed to provide high-bandwidth Control and Non-Payload Communications (CNPC). To enable the CNPC system and increase the util ...

To be useful for computational combustor design and analysis using tools like the National Combustion Code (NCC), low-dimensional chemical kinetic mechanisms for modeling of real fuel combustion chemistry must be sufficiently compact so that they can be utilized in multi-dimensional, multi-physics, reacting computational fluid dynamics (CFD) simulations. Despite advances in CFD-appropriate kinetic ...

To support NASA's vital interest in developing much larger solar array structures over the next 20 years, MotionPort LLC's Phase I SBIR project will strengthen validated modeling analysis and simulation techniques by developing a vertical application to simulate the nonlinear dynamics of the various stages of deployable space structures. This application which will support RecurDyn Multi-Body Dyn ...
