We propose a high-impact innovation for weather forecasting that integrates global ensemble weather forecasts with an AI-driven post-processing model of extreme weather indices. This innovation will provide the basis for skillful probabilistic forecasts of compound extreme weather events at extended lead times. Extreme weather/climate events of relevance to electric utilities focused on in Phase I ...

The objective of this proposal is the development and demonstration of a dynamic adaptive mesh refinement (AMR) capability for wall modeled large eddy simulations (WMLES) of complex configurations using arbitrary grid types including unstructured grids with hybrid element types. Our approach consists of linking legacy CFD codes to an octree mesh subdivision library, which is highly scalable and ca ...

The focus of this STTR proposal is on using Physics-Informed Machine Learning (PIML) and surrogate modeling to reduce the bottleneck of High-Fidelity Aeroelastic Stability models that are required for any airworthiness certification.Traditional approaches to solving targeted problems such as aviation certification often require the use of physics-based modeling and simulation (M&S) in combination ...

The objective of this proposal is the implementation of a high-fidelity Computational Fluid Dynamics-Computational Aeroacoustics (CFD-CAA) simulation capability for accurate noise prediction of installed contra-rotating rotor (CROR) configurations. The key technology that allows for the success of the project is the use of an acoustic analogy based on surface and volume integrals coupled to a dual ...

The objective of this Phase 1 proposal is the Graphical-Processing-Unit (GPU) acceleration of a two-dimensional, unstructured, viscous Navier-Stokes (NS) solver for aerothermodynamic applications. The subject code employs a multi-species two-temperature chemically reacting real gas model and incorporates the exact discrete tangent and adjoint systems for the real-gas system, which has been used fo ...

With the Artemis program, NASA is returning to manned space flight and plans to send humans to the Moon and Mars in the decades to come. New space vehicles and systems are being developed and tested, and a significant percentage of the structures in these spacecraft will be composite materials. Composites offer high stiffness- and strength-to-weight ratios, but they also exhibit complex damage mod ...

This SBIR Phase I will formulate and test a metal/WS2 Composite Dry Film Lubricant.The variables which will affect the result are the carrier gas temperature, the impact velocity on the substrate and the ratio of WS2 to metal.Three different metals are being explored to increase chances of success. Harder, higher melting point metals like Ti64 are more challenging for the Cold Spray technique, but ...

NASA is developing new spacecraft for human spaceflight. These spacecraft will utilize a variety of material systems, and many of the components are targeted for reusability and long-term use. This offers many challenges, not only for design and manufacturing, but also for inspection and maintenance. For example, inspection of thermal protection systems (TPS), bondlines, or multilayered structures ...
