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 ...

Space superiority requires space protection and space situational awareness (SSA), which rely on rapid and accurate space object behavioral and operational intent discovery. The presence of adversaries in addition to real-time and hidden information constraints greatly complicates the decision-making process in controlling both ground-based and space-based Air Force surveillance assets. The focus ...

N5 Sensors partnering with George Mason University (GMU) have demonstrated ultra-small, low-power gas sensors, ideally suited for integrated space suit monitoring. A single-chip carbon dioxide (CO2), oxygen (O2), and ammonia (NH3) sensors capable of operating at high-humidity conditions, different range of oxygen in the environment and with low-power consumption was demonstrated as a proof-of-conc ...

There is a DoD need for the development of robust sensors to obtain temporally and spatially resolved surface temperature and heat flux measurements on test articles in blowdown and continuous hypersonic wind tunnels. These micro-heat flux sensors are required in order to better understand the state of the boundary layer of a hypersonic vehicle; to better understand boundary layer instabilities; a ...

The problem addressed in this effort is to automatically learn historical ephemeris space catalog time, position, and velocity entity track update error uncertainties (i.e., without track error covariances) and to automatically (e.g., without expert event labeling) produce: – unmodeled non-gravitational space catalog update flags – abnormal unmodeled catalog update flags with abnorma ...

Near-Earth space environment is hazardous to satellites. This harsh particle radiation can penetrate protective shielding, accumulate in sensitive materials and can damage even well shielded electronic components causing temporary malfunctions or a complete system/mission loss. The goal of the proposed work is to provide the Air Force with a state-of-the-art model of the outer zone energetic elect ...

This project will provide state-of-the-art predictive capabilities for simulating systems central to advancing the U.S. Army’s modernization priorities related to long-range precision fires and future vertical lift platforms. The goals of the project are to: (1) Produce geometry and meshing technologies that support the modeling and discretization techniques needed to explicitly track evolving/i ...

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase II project is the development of software to help bioscientists analyze more tissue in less time and with higher accuracy and reproducibility. Currently, stereology studies require a trained technician to sit before a computer screen, making tedious manual counts (clicks) on hundreds to thousands of mic ...

Ischemic stroke is a leading cause of death and disability in the United States. This often is attributable to thrombus formation at an atherosclerotic plaque or thromboembolism. Patients who present within 4.5 hours of symptom onset are eligible for thrombolysis with tissue plasminogen activator (tPA). This serves andlt;5% of victims. Recently, major advance has been made with proven efficacy fro ...
