  1. Advanced Hot Reservoir Variable Conductance Heat Pipes for Planetary Landers

    SBC: Advanced Cooling Technologies, Inc.            Topic: T9

    In contrast to the standard cold reservoir Variable Conductance Heat Pipe (VCHP) where for tight thermal control an electrical heater is used for the reservoir (wicked), Advanced Cooling Technologies, Inc (ACT) developed a hot reservoir VCHP with the reservoir thermally coupled to the evaporator. This novel feature will provide a tight temperature control capability without the need for control po ...

  3. An Automated High Aspect Ratio Mesher for Computational Fluid Dynamics

    SBC: Ciespace Corporation            Topic: T801

    Computational fluid dynamics (CFD) simulations are routinely used while designing, analyzing, and optimizing air- and spacecraft. An important component of CFD simulations is mesh generation, or discretization into polygonal or polyhedral cells, of the domain being analyzed. The overall computational cost and accuracy of simulations depend heavily on mesh quality – the size, shape, and structur ...

  4. Autonomous Navigation on Icy Moons and Ocean Worlds

    SBC: VETH RESEARCH ASSOCIATES LLC            Topic: T4

    Technology currently used for terrestrial navigation is extremely limited in the challenging environments on icy moons and ocean worlds such as Europa. Autonomous platforms used to collect data from beneath these ice and ocean surfaces cannot depend on access to satellite or any other electromagnetic communication. Autonomous systems in these environments are required to perform highly-complex tas ...

  5. Concurrent High-Fidelity Measurements and Simulations for Advancing the Design of Rotating Detonation Engines

    SBC: SPECTRAL ENERGIES LLC            Topic: T2

    Rotating Detonation Engine (RDE) design is challenging due to the lack of in-depth understanding of many key mixing and combustion processes. The RDE flow field is a nonuniform mixture of fuel and oxidizer concentrations with strong injector effects, large turbulence effects, multiple shockwaves, and shear layers. These inhomogeneities can lead to significant combustion inefficiencies which have a ...

  6. Deep Learning Applied to Detecting Salient Features and Building Better 3D Models

    SBC: Mesh Robotics, LLC            Topic: T4

    We propose to develop a method to effectively utilize the massive amount of image and range data that cameras and laser scanners can generate for an autonomous navigation system. Our innovative approach is to use deep learning to detect and segment only the most useful portions of the data and to use that to build better 3D models. We have proven methods for building accurate 3D models of the en ...

  8. Gaseous Helium Reclamation at Rocket Test Systems

    SBC: Sierra Lobo, Inc.            Topic: T1001

    The ability to restore large amounts of vented gaseous helium (GHe) at rocket test sites preserves the GHe and reduces operating cost. The used GHe is vented into the atmosphere, is non-recoverable, and costs NASA millions dollars per year. Helium, which is non-renewable and irreplaceable once released into the atmosphere, is continuously consumed by rocket test facilities at NASA centers such a ...
