New Integrated Total Design of Unmanned Underwater Vehicles (UUVs) Propulsion System Architecture for Higher Efficiency and Low NoiseSBC: CONTINUOUS SOLUTIONS LLC Topic: N18AT012
In this proposal, a meta model-based scaling law will be used to represent each system component. A components meta model-based scaling law describes the tradeoffs between performance metrics for that component or subsystem as a function of its ratings in relation to the system. This greatly reduces the number of degrees of freedom for each component, and at the same time, retains the information ...STTR Phase I 2018 Department of DefenseNavy
SBC: D'Angelo Technologies, LLC Topic: N18AT014
There is a need to create an automated, adaptive, real time coaching module that can integrate the Conning Officer Virtual Environment (COVE) along with the associated Intelligent Tutor System (COVE-ITS) and the Conning-Officer Ship Handling Assessment (COSA) together. By automating the evaluation process, Surface Warfare Officers (SWOs) will have the opportunity to use the COVE simulations more f ...STTR Phase I 2018 Department of DefenseNavy
Quantifying Uncertainty in the Mechanical Performance of Additively Manufactured Parts Due to Material and Process VariationSBC: MRL MATERIALS RESOURCES LLC Topic: N16AT004
Additive manufacturing is an extremely customizable process; however, variations in the chosen build parameters can lead to drastic differences in part performance. The performance variation due to process parameters is still not well understood, and propagating all uncertainties from the various sources has been a challenge. Sources of AM parts’ performance variability include uncertainties in ...STTR Phase II 2018 Department of DefenseNavy
Optimized High Performance Stainless Steel Powder for Selective Laser Melting Additive Manufacturing (AM)SBC: SHEPRA, INC. Topic: N16AT007
Stainless steel is a vital component of many air, land and sea systems that support the Navy warfighter. In particular, 17-4 precipitation hardened stainless steel, (17-4 PH SS) with its extrodinary combination of strength, ductility, high temperature performance and corrosion resistance plays an important role in supporting the warfighter. When processed conventionally, 17-4 PH SS typical exhibit ...STTR Phase II 2018 Department of DefenseNavy
SBC: ISSAC Corp Topic: N16AT009
During the Phase II effort, the ISSAC Team will investigate several objectives and questions posed in Phase I efforts, in order to best develop a draft specification for NGES MVDC DLI systems. This includes exploring notional and conceptual architectures and discerning thresholds for DLI parameters; exploring individual and hybrid protection plan technologies to drive performance requirements for ...STTR Phase II 2018 Department of DefenseNavy
SBC: CONTINUOUS SOLUTIONS LLC Topic: N16AT012
During the Phase 1 effort, there were several achievements toward the design of grounding systems for MVDC architectures. For one, the common-mode equivalent circuit (CMEC) modeling approach that was derived at Purdue under ESRDC funding, was validated in a reduced-scale hardware setup at Purdue. The system studied consisted of a single generator, active rectifier, inverter, and propulsion machine ...STTR Phase II 2018 Department of DefenseNavy
SBC: MAINSTREAM ENGINEERING CORP Topic: N16AT014
The heat load from Navy combat system electronics housed in Mission Critical Enclosures (MCEs) continues to increase. During Phase I, Mainstream designed and demonstrated a modular, scalable thermal management system (TMS) for existing and future MCE cabinets with triple the cooling capacity of the legacy TMS. In Phase II, Mainstream will transition the TMS to the Navy for retrofit and next-genera ...STTR Phase II 2018 Department of DefenseNavy
Integrated Computational Material Engineering Approach to Additive Manufacturing for Stainless Steel (316L)SBC: SENVOL LLC Topic: N16AT022
The objective in this project is to implement and validate a probabilistic qualification framework that will enable additive manufacturing (AM) materials and part qualification through the use of a data-driven predictive model within a statistical framework. Senvol seeks to develop and validate a data-driven ICME probabilistic framework for assisting qualification of AM materials and parts. Phase ...STTR Phase II 2018 Department of DefenseNavy
SBC: AGNITRON TECHNOLOGY, INC. Topic: N16AT023
xß-Ga2O3 has emerged as a potentially disruptive semiconductor with a predicted breakdown field of ~8 MV/cm which is more than twice the breakdown field for the incumbent wide bandgap semiconductors GaN and SiC. The availability of ß-Ga2O3 bulk substrates sets this material apart from other wide bandgap materials for power electronic applications. However, the challenge is to find suitable epita ...STTR Phase II 2018 Department of DefenseNavy
SBC: PLASMONICS INC Topic: N17AT020
There is a critical need for the development of dynamic IR materials that can be used to form device level components and systems necessary for mid to long wave infrared (3-12 µm) applications. To meet these future needs, the team proposes to develop tunable optical elements based around metamaterial surfaces or metasurfaces. Metasurfaces are a class of engineered materials where arrays of sub-wa ...STTR Phase II 2018 Department of DefenseNavy
