  1. Advanced Particle-in-Cell (PIC) Tools for Simulation of Electrodynamic Tether Plasma Interactions

    SBC: TECH-X CORPORATION            Topic: T301

    Electrodynamic tethers are optimally suited for use in Low-Earth-Orbit (LEO) to generate thrust or drag maneuver satellites. LEO region is polluted with space debris from the left over of rockets and abandoned satellites. It becomes important to clean them, i.e., de-orbit and ED tethers are promising for such applications. ED tethers are operating without propellants, so less polluting in our spac ...

  2. Non-Catalytic Self Healing Composite Material Solution

    SBC: ADA Technologies, Inc.            Topic: T901

    Fiber reinforce polymer (FRP) composite materials are seeing increasing use in the construction of a wide variety of aerospace structures. However, uncertainties regarding the material's impact durability continue to plague the FRP composites community. To address this need, ADA Technologies, Inc. (ADA), Littleton, CO, in partnership with the University of Delaware's Center for Composi ...

  3. Helium-Hydrogen Recovery System

    SBC: TDA Research, Inc.            Topic: T1002

    Immense quantities of expensive liquefied helium are required at Stennis and Kennedy Space Centers for pre-cooling rocket engine propellant systems prior to filling with liquid hydrogen, for pressurizing tanks and for safely purging residual hydrogen. Presently, the helium used in these processes is discarded, along with substantial quantities of hydrogen. TDA Research proposes to design and build ...

  4. Prognostics Enhancemend Fault-Tolerant Control with an Application to a Hovercraft

    SBC: Impact Technologies            Topic: T101

    Fault-Tolerant Control (FTC) is an emerging area of engineering and scientific research that integrates prognostics, health management concepts and intelligent control. Impact Technologies and the Georgia Institute of Technology, propose to build off of a strong foundation in fault-tolerant control (FTC) research performed with NASA in past years to mature the applicability of this technology and ...

  5. Next-Generation Ion Thruster Design Tool to Support Future Space Missions

    SBC: TECH-X CORPORATION            Topic: T301

    Computational tools that accurately predict the performance of electric propulsiondevices are highly desirable and beneficial to NASA and the broader electric propulsioncommunity. The current state-of-the-art in electric propulsion modeling relies heavily onempirical data and on numerous computational "knobs". In Phase I of this project, wedeveloped the most detailed ion engine discharge ...

  6. Generation and Adaptive Modification of Anisotropic Meshes

    SBC: SIMMETRIX INC.            Topic: T801

    The ability to quickly and reliably simulate high-speed flows over a wide range of geometrically complex configurations is critical to many of NASA's missions. Advances in CFD methods and parallel computing have provided NASA the core flow solvers to perform these simulations. However, the ease of use of these flow solvers and the reliability of the results obtained are a strong function of t ...
