SBC: SIMMETRIX, INC. Topic: N13AT002
Integrally bladed rotors (IBR), also called blisks, are becoming increasingly common in the compressor and fan sections of modern turbine engines. The integration of the blades and disks into a single part has the advantages of reduced part count, reduced weight, increased reliability, and increased performance. However, a drawback of this technology is that individual blades cannot be easily repl ...STTR Phase I 2013 Department of DefenseNavy
Maneuver Prediction and Avoidance Logic For Unmanned Aircraft System Encounters with Non-Cooperative Air TrafficSBC: NUMERICA CORPORATION Topic: N13AT003
For Unmanned Aircraft Systems (UAS) to operate seamlessly in both the U.S. National Airspace System (NAS) and abroad, it will be crucial that they possess a sense-and-avoid (SAA) capability that can ensure safe operations among maneuvering, non-cooperative aircraft. Numerica Corporation, in partnership with Johns Hopkins University, proposes to develop a set of algorithms to model the uncertaintie ...STTR Phase I 2013 Department of DefenseNavy
SBC: TECHNICAL DATA ANALYSIS, INC. Topic: N13AT007
TDA and its University partner, Cornell University, first address the stress assisted corrosion crack growth from concurrent multi-scale modeling through atomistic simulations in order to formulate and calibrate mesoscale Peridynamics model. Initially, the multi-scale CADD simulations will utilize reactive force field potentials for the 7075-T6Al in water to simulate stress corrosion cracking and ...STTR Phase I 2013 Department of DefenseNavy
SBC: Thornton Tomasetti, Inc. Topic: N13AT008
Susceptibility to delamination is one of the major weaknesses of ceramic matrix composites (CMCs). Knowledge of the resistance of composite to interlaminar fracture is essential for life cycle prediction analyses of structural components. The current test method for Mode I-interlaminar fracture toughness, the double cantilevered beam (DCB), is not satisfactory for thin CMC specimens because the co ...STTR Phase I 2013 Department of DefenseNavy
SBC: Technosoft, Inc Topic: N13AT009
Although advancements in CFD technology and high performance computing have proven to be effective and reasonably accurate in assessing the hydrodynamic performance of naval vessels, the effort required to develop associated analysis models remains a challenging and time consuming task. Decomposing and manipulating the design geometry for mesh construction, while capturing near-field and far-field ...STTR Phase I 2013 Department of DefenseNavy
Mechanical Property Characterization and Modeling for Structural Mo-Si-B Alloys for High Temperature ApplicationsSBC: Imaging Systems Technology, Inc. Topic: N13AT012
Under this STTR, Imaging Systems Technology (IST) in cooperation with Georgia Institute Technology (GIT) will develop and mature models to predict mechanical properties of refractory alloys with an eye toward tailoring these alloys for specific applications. In particular, this research will focus on addressing core aspects of Integrated Computational Materials Engineering (ICME) as it applies to ...STTR Phase I 2013 Department of DefenseNavy
Mechanical Property Characterization and Modeling for Structural Mo-Si-B Alloys for High Temperature ApplicationsSBC: Deep Springs Technology Topic: N13AT012
The objective of the work described in this proposal is to aid in the advancement of Mo-Si-B alloys for use in high temperature applications such as hot gas stream components in turbine engines. Such alloys are being characterized for their monotonic tensile properties in tension and compression as well for their creep resistance. Likewise, multiphase Mo-Si-B alloys have been studied in terms of m ...STTR Phase I 2013 Department of DefenseNavy
Probiotics for Maintaining Dolphin (Tursiops truncatus) Health and the Readiness of the U.S. Navy"s Marine Mammal SystemsSBC: AGAVE BIOSYSTEMS INC. Topic: N13AT013
Agave BioSystems, with their academic partners at the Mote Marine Laboratory, proposes to develop probiotic pharmaceuticals from indigenous commensal microbes to enhance gastrointestinal health in the bottlenose dolphin (Tursiops truncatus). The dolphin gastrointestinal microbiome will be characterized by 16S rRNA deep sequencing, and culturable commensals will be isolated by plating dolphin gastr ...STTR Phase I 2013 Department of DefenseNavy
SBC: GRAMMATECH INC Topic: N13AT014
Software continues to be a weak link in our critical systems. A prudent operator should employ a defense-in-depth strategy whereby"safe"systems are still monitored to detect breaches and respond to them. Unfortunately, such monitoring is challenging in practice, since there is no universal pattern that characterizes misbehaving software. We will capture an application"s intended behavior as it is ...STTR Phase I 2013 Department of DefenseNavy
SBC: SECURBORATION, INC. Topic: N13AT014
Complex software systems are typically developed by disparate engineering teams working concurrently. At the same time, software requirements are frequently dynamic, evolving even during active development cycles. Discrepancies between how software is defined and how it is implemented at the modular level can cascade into critical system errors when modules are integrated. More troubling is that i ...STTR Phase I 2013 Department of DefenseNavy
