Arctic Slope Technical Services, Inc. (ASTS) is pleased to propose to continue the development of an additive manufacturing (AM) approach for fabricating bimetallic combustion chambers. Our chamber design, which is applicable to future NASA small launch vehicles, exploits the combined capabilities of selective laser melting (SLM) and magnetic pulse welding (MPW), in order to reduce manufacturing ...

THIS EFFORT WILL ENHANCE THE CAPABILITY OF THE AIR FORCE PARABOLIZED NAVIER STOKES CODE (AFWAL PNS CODE) TO PREDICT SKIN FRICTION AND HEAT TRANSFER TO HIGH SPEED FLIGHT VEHICLES. THE CURRENT PREDICTION TECHNIQUES REQUIRE EXTREMELY ACCURATE CALCULATIONS OF VELOCITY AND TEMPERATURE IN THE VICINITY OF THE WALL. THE EFFORT HERE WILL REPLACE THIS PROCEDURE BY USING INTEGRAL MOMENTUM AND ENERGY EQUATION ...

Accurate real-time microbial monitoring of water environment is of paramount importance to crew health as well as to ensure proper functioning and control of the life support system during space exploration. The existing methods are time-consuming and labor-intensive, and the devices used are bulky, consumable-hungry, and ill-suited for spacecraft deployment. We propose to develop and demonstrate ...

Under the support of a FY 2016 NASA Phase I Small Business Technology Transfer (STTR) contract (NASA contract number NNX16CM40P), Morningbird Media Corporation in collaboration with Alabama A&M University Research, Innovation in Science and Engineering (AAMU-RISE) Foundation, has devised a unique method for an additive manufacturing technique for the direct 3D printing of functional electronics. T ...

THE OVERALL CYCLE EFFICIENCY (HENCE, INPUT POWER REQUIREMENTS) OF REVERSE-BRAYTON CRYOCOOLERS FOR SPACE APPLICATIONS IS HIGHLY SENSITIVE TO THE THERMAL EFFECTIVENESS OF THE HEAT EXCHANGERS. APPLICATIONS FOR THESE CRYOCOOLERS IN SPACE DICTATE THAT THESE HEAT EXCHANGERS BE AS SMALL AND LIGHT AS POSSIBLE. TO DATE, ONLYHEAT EXCHANGERS EMPLOYING ORGANIC MATERIALS HAVE BEEN ABLE TO ACHIEVE THE HIGH THER ...

A NEW SYSTEM, THE ANNULAR FLOW ELECTROTHERMAL PLUG RAMJET, IS PROPOSED AS A ALTERNATIVE TO CHEMICAL ROCKETS AND ELECTROMAGNETIC LAUNCHERS AS A KINETIC ENERGY WEAPON. THIS SYSTEM APPEARS TO BE CAPABLE OF ACHIEVING THE HYPERVELOCITIES NECESSARY IN REASONABLE LAUNCHER LENGTHS, PRIMARILY BECAUSE IT DOES NOT ACCELERATE EITHER THE PROPELLANT OR THE PROPULSION SYSTEM REQUIRED TO ACHIEVE HYPERVELOCITIES. ...

Current drug discovery and development efforts are severely limited by expensive animal trials and oversimplified in vitro models. Results obtained from in vitro models are not predictive of in vivo toxicity owing to significant difference from the in vivo physiological conditions. In this context, we propose to develop and demonstrate a novel microfluidic device that reproduces the physiological ...

Product Authentication protects the CPI through the Weapon System Life Cycle. LIT Product Authentication is structured into two major components. The Product Authentication Key System (PAKS) derives cryptographic keys from authentication codes provided by the Product Authentication Sensor System (PASS). Equipment lost or compromised is protected from reverse engineering since any effort to open ...

Electric propulsion represents an attractive path for reducing overall emissions. For larger commercial aircrafts operating in the mega-watt range, power turboelectric and hybrid electric aircraft propulsion will continue to rely on gas turbine engines/generators to provide part of the thrust, charging batteries and driving generators. As a result, reduction of emissions such as oxides of nitrogen ...

NASA’s future remote sensing science missions require advanced thermal management technologies to maintain multiple instruments at very stable temperatures and utilize waste heat to keep other critical subsystems above minimum operational temperatures. Two-phase pumped loops are an ideal solution for these applications. A critical need for these pumped loops is a microgravity-compatible evaporat ...
