This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed.Process optimizations will be conducted ...

To address the urgent need for 3D flash-lidar technology for landing on solar system bodies and for spacecraft rendezvous and docking with satellites, an effort is proposed to fabricate, characterize, and test a versatile, high-sensitivity InGaAs APD 3D flash lidar and to advance the technology-readiness level (TRL) of lidar technologies suitable for NASA mission requirements. Leveraging an existi ...

This STTR program will mature high density, high regression rate hybrid rocket motor technology through TRL6 through the design, fabrication, and testing of third and fourth stage nanosatellite motors, while preparing designs and sizing for booster stages.nbsp; Hybrid Rockets offer substantially lower cost compared to storable and cryogenic bipropellant systems, but currently suffer from poor pack ...

The proposed Phase II supports completion of the RINGS science missions on ISS using SVGS as real-time sensor for the EMFF maneuver. During Phase I, SVGS-based navigation of RINGS was developed and tested on a 3DOF ground-based platform, and mechanical and electrical integration of RINGS with the free-flying robotic platforms on ISS (Astrobee) was designed in detail. SVGS was deployed and tested o ...
