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 ...

The key objective of the Phase II Sequential project is to develop and demonstrate a fully-autonomous,nbsp;large-scale hydrogen recovery and compression system that can be used as a modular building block to reclaim and compress a substantial portion of SSCrsquo;s hydrogen. Specific goals for the Phase II Sequential program effort are:Improve in-cell and stack water management, along with flow dis ...

The technical objectives of this program are: (1) to develop a set of physics-based modeling tools to predict the initiation of hot corrosion and to address pit and fatigue crack formation in Ni-based alloys subjected to corrosive environments, (2) to implement this set of physics-based modeling tools into the DARWIN probabilistic life-prediction code, and (3) to demonstrate corrosion fatigue crac ...

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 ...

Frequency selective surfaces (FSSs) are periodic arrays of conductive elements/patches that cause a particular reflection response when illuminated with high frequency electromagnetic energy. nbsp;These arrays arenbsp;used for high frequency filters and in antenna applications.nbsp; We propose to use FSSs as multi-functional sensors. nbsp;FSS sensors are unpowered, low-profile (thin), wireless and ...

Thegoal is to develop asoftwaretool that implementsa novelapproach applicableto fitgeneral pharmacologic, toxicology, or other biomedical data, that mayexhibita non-monotonic dose-responserelationship for which thecurrent parametricmodels fail. Thesoftwareexplores dose-responserelationships using both monotonicand non-monotonicmodels,and estimates theassociated doseresponsecurves,which can further ...

Distributed Spacecraft Missions (DSM) architectures provide unique scientific and programmatic benefits including multipoint in-situ measurements, multi-angle viewpoints, and improved understanding of the connections between separately measured phenomena and their time variations. However, these missions impose significant operational demands on ground tracking resources and mission operators alik ...

Luna will team with Dr. John Bowers of UCSB to continue development of an Optical Frequency Domain Reflectometry (OFDR) system-on-chip using heterogeneous silicon photonics to enable a minimal weight structural health monitoring system. This system-on-chip will be the building block for distributed sensing interrogation systems that are the size of a deck of playing cards. This lightweight, rugged ...
