Award Data

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 ...

Foil/air bearings have the benefit of negligible friction and wear once sufficient airflow is obtained; however, during spin up and spin down these bearings are subject to contact with the rotating surfaces upon which they act and thus are subject to frictional losses and wear. Modern air-cycle machines (ACMs) depend on solid lubricant based coating materials such as polyimide coatings to protect ...

Oceanit proposes to develop and demonstrate novel, tailored, designer separator materials with optimized properties to maximize lithium-ion cell/battery performance, life, safety and reliability.

The objective of STTR Topic N16A-T013, Cyber Forensic Tool Kit for Machinery Control, is to develop live digital forensics that, at run time, provide a cyber-protection strategy and aid in identification of malfunctions due to malicious and non-malicious events, while ensuring minimal impact on overall system performance. A proposal has been prepared by TDI Technologies, Inc., a small business bas ...

Military and civilian agencies can benefit from systems that create 4D, spatio-temporal representations of dynamic scenes for target tracking, law enforcement, crowd control, disaster recovery, etc. Proliferation of imaging sensors such as surveillance cameras, car- and body-mounted cameras, and cell phones, provides the opportunity for reconstructing a dynamic scene in a very inexpensive way. Tod ...

Navy needs a real-time graph embedding tool for analyzing huge graphs (millions of nodes and billions of edges) from diverse sources. However, current approaches cannot provide dynamic and scalable graph analytics to show the military value of tactical data. In this project, InfoBeyond advocates EStreaming (Embedding & Streaming) for scalable and efficient graph streaming. EStreaming promotes big ...

In this STTR, Daniel H. Wagner Associates, together with the University of Michigan (UM), will develop a Detection Avoidance System for Submarines (DASS). The proposed DASS is a set of software modules which solves the probabilistic passive sonar equation (PSE) using given environmental acoustic data, assesses submarine vulnerability based on intelligence about potential threat ASW assets, recomme ...

Aviana Molecular (Aviana) and the University of Central Florida (UCF) propose to develop a Passive Wireless Sensor System (PWSS) for Structural Health Monitoring (SHM). SAW sensors are lightweight, passive (battery-less), simple, reliable, scalable, sensitive, do not disturb the operating environment, can be permanently placed on the critical components, allow quick and inexpensive acquisition of ...

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 ...
