The proposed technology builds off GTL's advanced solid ramjet fuel. The method uses additive manufacturing methods to produce an innovative new type of fuel grain that regresses quickly and has a high Isp and combustion efficiency. With this technology, the performance of a liquid rocket engine can be had with a hybrid rocket system. This technology allows for a simple, low cost, high performanc ...

GTL?s SNS technology aids in the operation of new or existing structural health monitoring (SHM) systems by integrating data and power pathways into the structure. The use of this technology within a composite structure would allow engineers to place sensors from an SHM system directly where they are needed on a structure with instant power. GTL?s SNS technology offers the potential for developers ...

DEC-Shield technology offers the means to generate electric power from cosmic radiation sources and fuse dissimilar systems and functionality into a structural component to create a Multi-functional Structure (MFS). DEC-Shield integrated into MFS technology can be used to generate electric power and provide radiation protection in a space vehicle; even maximizing that protection by spreading the ...

Computational fluid dynamics (CFD) simulations are routinely used by NASA to optimize the design of propulsion systems. Current methods for CFD modeling rely on general materials properties to determine fluid structure interactions. This introduces uncertainty when modeling extreme conditions, where materials degrade and properties may change as a consequence. This also limits the use of CFD as a ...

High-energy space radiation from Galactic Cosmic Rays and Solar Particle Events (SPEs) pose significant risks to equipment and astronaut health in NASA missions. In particular, energetic particles from SPEs associated with flares and coronal mass ejections (CMEs) constitute a highly dynamic and penetrating radiation environment that may adversely affect not only beyond-Low-Earth-Orbit missions, bu ...

Despite the rapid commercialization of additive manufacturing technology such as selective laser melting, SLM, there are gaps in process modeling and material property prediction that contribute to slow and costly process development, process qualification and product certification. To address these gaps, CFDRC and our partner Dr. Kevin Chou, University of Alabama, will develop multiple computatio ...

Advanced turbomachinery components play a critical role in launch vehicle and spacecraft liquid rocket propulsion systems. To achieve desired efficiencies, extremely tight tolerances are often imposed between inducer blades and shrouds or other system components which sets up strong interactions that influence both the aerodynamics and the structural performance of blades and vanes. These transien ...

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 ...

High-energy space radiation from Galactic Cosmic Rays and Solar Particle Events (SPEs) pose significant risks to equipment and astronaut health in NASA missions. Energetic particles from SPEs associated with flares and coronal mass ejections (CMEs) may adversely affect not only beyond-Low-Earth-Orbit missions, but also aircraft avionics, communications, and airline crew/passenger health. It is cru ...

Chromologic (CL) and the California Institute of Technology (Caltech) propose to develop and demonstrate a Multifunctional Environmental Digital Scanning Electron Microprobe (MEDSEM) instrument that transmits high-energy beams of electrons sequentially from a two-dimensional array of miniaturized electron probes into a planetary atmosphere, and these electrons will strike solid or liquid planetary ...
