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 ...

Newly developed phase-engineered and low dimensional materials have opened the door to the design of materials structures that exhibit extremely efficient ionic transport. Recently, a new type of electro-filtration system designed to convert thermal power into purified water from salt water (or other ionic pollutants) has been demonstrated in the lab. The system is based on a bi-phasic nanoplate ...

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 ...

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 ...

Boulder Nonlinear Systems (BNS) and University of Dayton (UD) will team on development of a non-mechanical beam steering (NMBS) subsystem for Entry, Descent and Landing (EDL) sensors. BNS will improve their current polarization grating (PG) technology which is capable of switching well over the +- 25 degree requirement called for in the solicitation. Advances to the PG technology specific to the ...

Extravehicular Mobility Units (EVU) are the necessary to perform elaborate, dynamic tasks in the biologically harsh conditions of space from International Space Station (ISS) external repairs to human exploration of planetary bodies. The EVUs have stringent requirements on physical and chemical nature of the equipment/components/processes, to ensure safety and health of the individual require prop ...

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 ...

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, ...

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 ...

We propose a spectrometer that employs a single room temperature semiconductor detector that can perform both gamma and neutron spectroscopy. The proposed detector is based on the novel mercurous halide materials, Hg2X2 (X=I, Cl, Br). The mercurous halides are new wide band-gap semiconductor detector materials that can provide radiation detection with low cost, high performance and long term stab ...
