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 Phase II project aims to assemble the key set of sensor modalities that are needed to reliably view the key process anomalies and properties of laser powder bed fusion. The research team will down-select from the Phase I sensors investigated and integrate the sensors into a sensor fusion software package that facilitates data collection and synchronization, and eventually feedback control of ...

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 ...

Augmented reality (AR) offers the ability to enhance existing combat medic training by including perceptual cues and adaptive training elements to traditional simulation-based training using manikins. Unveil has developed a training system called the Macrocognitive AR Trainer (MART). MART is designed to foster the development of macrocognitive skills (e.g., sensemaking, assessment skills, mental m ...

Providing Army combat medics with meaningful experience in treatment of battlefield injuries is a particular challenge. Moulage has the potential to assist in acquiring what could otherwise be very hard-to-come-by preparatory experience for distressing real-life emergencies medics and soldiers may encounter in the field. However, current approaches to moulage are limited in their ability to reflec ...

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 ...

NASA wants a cost-effective atmospheric remote sensing system providing accurate temperature and humidity profiles to least 10 km height in clear and cloudy conditions. Radiometrics Microwave Profiler (MP) products currently provide accurate temperature and humidity profiles in good agreement with radiosondes to 3 km height. Good agreement can be extended beyond 10 km height using variational retr ...

Solid rocket motor (SRM) design requires detailed understanding of the slag accumulation process in order to: predict thrust continuity, optimize propellant conversion efficiency, predict coning effects from sloshing, and to 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 ...
