This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing methods. Copper to Nickel alloy interface strength will be quantified and metallurgical characterization completed. A thermal model based on Rosenthal?s analytical expression for a moving heat source, which has ...

The proposed 9-month research project aims for the development of additive manufacturing techniques for the creation of electronic devices. It will develop an innovative additive manufacturing technique that combines the ink-based printing with laser melting technology to directly print a three-dimensional (3D) system with built-in electrical properties and functioning as an electronic device. Th ...

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 ...

Using novel materials and device geometries unique to North Carolina State University (NCSU) and Third Floor Materials (3FM) this program will develop a detector technology that enables room-temperature multispectral IR imaging by exploring transduction pathways between infra red light and a measureable electric signal mediated by an epsilon-near-zero (ENZ) mode. The research activity will use a c ...

While much attention is necessarily focused on the evaluation and certification of the materials and processes involved in adhesive bonding, development is still needed in decreasing the cost, time, and complexity of the current repair concepts. A material and processing system is needed that allows the design, infusion, and cure of composite repairs without the current roadblocks imposed by ovens ...

Fibertek, Inc. in partnership with researchers at the Pennsylvania State University Center for Innovative Materials Processing through Direct Digital Deposition (CIMP-3D) are proposing to develop a state of the art, space-qualifiable laser transmitter that meets the requirements of the flash lidar transmitter defined in the 2016 STTR subtopic T9.01, Navigation and Hazard Avoidance Sensor Technolog ...

This NASA Phase I SBIR program would fabricate wireless networked nanomembrane (NM) based surface pressure sensors for remote monitoring in propulsion systems, using SOI (Silicon on Insulator) NM techniques in combination with our pioneering HybridSil ceramic nanocomposite materials. Such low-modulus, conformal nanomembrane sensor skins with integrated interconnect elements and electronic devices ...

Through the proposed STTR program, NanoSonic and Virginia Tech will create an innovative low viscosity, high Tg copolymer injection repair material and methodology that enables fiber reinforced composite repair within a short time frame in areas with limited user access. The proposed injection repair material will consist of fluidic HybridSil poly(siloxane imide) resins that are molecularly engine ...

Future long-duration, crewed space habitat systems will be inflatable structures. This type of structure is advantageous in that it is not limited to the diameter of the launch vehicle and can therefore provide a greater volume of living and work space. Unlike conventional metal structures, however, softbody inflatables require support members to maintain their desired shapes. Despite their robust ...

TDA Research Inc.(TDA) in collaboration with University of Puerto Rico ? Mayaguez (UPRM is proposing to develop a highly efficient CO2 removal system based on UPRM proprietary strontium exchanged silico-alumino-phosphate (Sr-SAPO-34) for closed loop space craft cabin air re-vitalization during deep space missions.
