Award Data

Computational fluid dynamics (CFD) simulations are routinely used by NASA to optimize the design of propulsion systems. Current methods for CFD modeling rely on general materials properties to determine fluid structure interactions. This introduces uncertainty when modeling extreme conditions, where materials degrade and properties may change as a consequence. This also limits the use of CFD as a ...

To provide additional telemetry and data for long-term mission, the composition of internal atmosphere of spacesuits must be determined. Specifically, the unambiguous detection and quantification of carbon dioxide is crucial for mission completion. Detection of other gasses (ammonia, oxygen) is also necessary for a complete sensor suite. Seacoast Science and Case Western Reserve University pro ...

Remote sensing, when combined with real-time processing, provides instant feedback on safety, mission success and system health. Being able to combine embedded sensing with distributed networks gives us the additional potential to further benefit many systems and sub-systems in the aerospace industry including launch vehicles, ground test equipment and spacecraft. These remote distributed sensor ...

M4 Engineering and Missouri S&T propose to investigate the viability of creating a multidisciplinary analysis and optimization architecture for analyzing spacecraft system models. The current approach will utilize commercial off-the-shelf (COTS) software to alleviate acquisition hurdles for NASA (and public) technical monitors/reviewers. Next, a preliminary set of analysis modules will be develo ...

A comprehensive model-based approach will be enabled for space systems design via the work started on Phase I of this project. The OpenMETA toolkit is a cyber-physical modeling tool for the design and virtual integration of complex systems, developed under the DARPA AVM Program. OpenMETA will be leveraged and extended to support NASA/JPL goals for multi-physics, multi-domain modeling, analysis, ...

Chromologic (CL) and the California Institute of Technology (Caltech) propose to develop and demonstrate a Multifunctional Environmental Digital Scanning Electron Microprobe (MEDSEM) instrument that transmits high-energy beams of electrons sequentially from a two-dimensional array of miniaturized electron probes into a planetary atmosphere, and these electrons will strike solid or liquid planetary ...

Chromologic (CL) and the California Institute of Technology (Caltech) propose to continue the Phase II STTR development and demonstration of a Multifunctional Environmental Digital Scanning Electron Microprobe (MEDSEM) instrument that transmits high energy beams of electrons sequentially using a two-dimensional array of multiple, miniaturized electron probes into a planetary atmosphere and strike ...

Despite the rapid commercialization of additive manufacturing technology such as selective laser melting, SLM, there are gaps in process modeling and material property prediction that contribute to slow and costly process development, process qualification and product certification. To address these gaps, CFDRC and our partner Dr. Kevin Chou, University of Alabama, will develop multiple computatio ...

The technical innovation proposed here is the design during Phase I of a high performance upper stage for a two-stage "20 / 450" Nanosat Launch Vehicle (NLV) that is configured to deliver up to 20 kg to a 450 km low Earth orbit (Figure 1). Parallel tasks prepare for the Phase II development and sub-orbital flight testing of a prototype vehicle that is directly traceable to the orbital-capable ...

HJ Science & Technology (HJS&T) and Georgia Institute of Technology (GIT) propose to develop a novel penetrator-compatible technology capable of detecting key organic molecules, biomarkers, and indicators of habitability on primary astrobiological targets including icy moons like Europa and Enceladus. The proposed innovation is a novel combination of microfluidic automated colorimetric and fluo ...
