  1. Unified In-Space Propulsion Framework for Prediction of Plume-Induced Spacecraft Environments

    SBC: CFD Research Corporation            Topic: T102

    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 ...

  2. Satellite Swarm Localization and Control via Random Finite Set Statistics

    SBC: ASTER LABS, INC            Topic: T403

    The proposed novel program will develop and demonstrate an innovative approach to perform real-time relative vehicle localization within a swarm formation with application to communication-less coordination. These objectives are achieved by using Random Finite Sets statistics theory to solve the multiple object tracking problem. The swarm formation localization problem can be formulated as estimat ...

  3. High Performance Simulation Tool for Multiphysics Propulsion Using Fidelity-Adaptive Combustion Modeling

    SBC: STREAMLINE NUMERICS, INC.            Topic: T102

    The innovation proposed here is a fidelity-adaptive combustion model (FAM) implemented into the Loci-STREAM CFD code for use at NASA for simulation of rocket combustion. This work will result in a high-fidelity, high-performance multiphysics simulation capability to enhance NASA's current simulation capability of unsteady turbulent reacting flows involving cryogenic propellants. This novel FAM m ...

  4. Transient Acoustic Environment Prediction Tool for Launch Vehicles in Motion during Early Lift-Off

    SBC: CFD Research Corporation            Topic: T102

    Launch vehicles experience extreme acoustic loads dominated by rocket exhaust plume interactions with ground structures during lift-off, which can produce damaging vibro-acoustic loads on the vehicle and payloads if not properly understood and mitigated against. Existing capabilities for modeling the turbulent plume physics during early lift-off are too dissipative to accurately resolve the propag ...

  5. Multiphase Modeling of Solid Rocket Motor Internal Environment

    SBC: CFD Research Corporation            Topic: T102

    Solid rocket motor (SRM) design requires thorough understanding of the slag accumulation process in order to: predict thrust continuity, optimize propellant conversion efficiency, predict coning effects from sloshing, and assess potential orbital debris (slag) hazard. Current state-of-the-art models for SRM environment do not have the capability to simulate the accumulation and dynamics of slag in ...

  6. Launch Weather Decision Support System

    SBC: Radiometrics Corporation            Topic: T103

    Launch safety and efficiency requires timely and accurate wind, thermodynamic and pressure information from the surface to 20 km height, and lightning risk identification. A Doppler radar now provides wind measurements that satisfy this requirement at the Eastern Test Range. Thermodynamic soundings are provided by intermittent radiosondes on launch day. Typical intervals of an hour or more between ...

  7. Efficient On-board Lamberts Solution for DSM

    SBC: Advanced Space LLC            Topic: T1102

    Distributed Spacecraft Missions (DSMs) such as constellations, formation-flying missions, and fractionated missions provide unique scientific and programmatic benefits. Distributed mission architectures allow for multipoint in-situ measurements, multi-angle viewpoints, and considerably improved understanding of the connections between separately measured phenomena and their time variations. DSMs a ...

  8. Prediction and Control of Selective Laser Melting Product Microstructure

    SBC: CFD Research Corporation            Topic: T1204

    Despite the rapid commercialization of additive manufacturing technology such as selective laser melting, SLM, there are gaps in models for material microstructure and property prediction that slow qualification and certification. Improvements in coupling microstructure prediction models to local process conditions, validation, and control of material microstructure are required to mature the stat ...

  9. Maneuvering Environment for Tiltwing Aircraft with Distributed Electric Propulsion

    SBC: EMBEDDED DYNAMICS LLC            Topic: T1501

    The tiltwing class of aircraft consists of vehicles with the ability to rotate the wing and propulsion system as a unit a full 90 degrees from the standard fixed wing configuration to one in which the wing and thrust axis become perpendicular to the body axis. This thrust vectoring capability allows the aircraft to utilize thrust borne flight for vertical takeoff and landing as well as the convent ...

  10. Reinforcement Learning For Coordination And Control of Swarming Satellites

    SBC: ASTER LABS, INC            Topic: T403

    Inspired by frequent observation of repetitive learned swarm behavior exhibited in nature, this novel program will develop and demonstrate new capabilities in decentralized control of large heterogeneous vehicle swarms limited in communication, sensors, and actuators, with direct application to communication-less coordination. These goals are accomplished through the adaptation and use of Reinforc ...
