THE MISSION OF THIS PHASE I PROJECT IS COMPLETION OF A TRULY INNOVATIVE STUDY TO UPGRADE EXISTING PNS CODES FOR COMPUTING HIGHSPEED, THREE-DIMENSIONAL RE-ENTRY FLOWFIELDS. THE PLAN OF ACTION ENCOMPASSES A THOROUGH EXAMINATION OF THE RANGE OF ADMISSABLE CFD THEORIES, TO UNEQUIVACALLY COMPARE STRONG AND WEAK POINTS FOR APPLICATION TO THE REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS WITH DIFFERENTIAL EQ ...

This proposal addresses the development of a Command Post and Acoustic Listening Posts for performing detection and automatic geo-location and classification of transient acoustic sounds associated with the firing of weapons, especially rockets, mortars, and artillery and the corresponding munitions impacts. Key components of the system are rugged low-noise infrasound sensors, state-of-the-art aco ...

In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

THE SAFETY OF THE FLYING PLATE DETONATOR IS KEY TO ITS USE IN IN-LINE FUZES. THE MAIN ADVANTAGE OF THE FLYING PLATE DETONATOR IS ONE OF ITS ADVANTAGES FROM A SAFETY VIEWPOINT; A SUBSTANTIAL AMOUNT OF ELECTRICAL ENERGY, ON THE ORDER OF A JOULE, MUST BE DELIVERED TO THE BRIDGE IN LESS THAN A MICROSECOND BEFORE THE UNIT WILL FIRE. THE FLYING PLATE DETONATOR, HOWEVER, HAS CHANGED LITTLE SINCE ITS ORIG ...

This project team will fully develop and test AlphaBear 2, a vocabulary learning game for grade 4 to 7 students. Vocabulary is a prerequisite for academic success, as it is linked to stronger performance across academic subjects and improved reading comprehension. It is more difficult for students to participate in educational activities without understanding the key vocabulary associated with tha ...

THE ARS-9 PRIMARY SURVEILLANCE RADAR HAS A DIGITAL OUTPUT INSTEAD OF THE ANALOG OUTPUT OF IT'S PREDECESSORS. THE COMPUTER AND DISPLAYS EQUIPMENT FOR NAVAL AIR TRAFFIC CONTROL COMPUTER NEEDS DIFFERENT DATA THAN THE ASR-9, NOW SUPPLIES. AN INTERFACE WILL BE DESIGNED THAT WILL TAKE THE OUTPUT OF THE ASR-9 EITHER FROM MODEM OR FIBER OPTICK LINK OR MICROWAVE LINK OR ON-SITE ATTACHMENT AND CONVERT FOR T ...

THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF AN AUTOMATED ALIGNMENT MEASURING SYSTEM FOR THE HYPERVELOCITY RANGE/TRACK G FACILITY, LOCATED AT ARNOLD ENGINEERING DEVELOPMENT CENTER. THE OBJECTIVES OF THIS RESEARCH AND DEVELOPMENT EFFORT ARE TO EVALUATE METHODS FOR DEVELOPING A SYSTEM THAT CAN RAPIDLY AND COST-EFFECTIVELY INSPECT THE TEST TRACK. THIS WILL REQUIRE AN IN-DEPTH UNDERSTANDING OF THE ENVIR ...

A SCANNING, PULSED DIODE LASER DOPPLER VELOCIMETER (DLDV/SP) WILL BE DEVELOPED FOR FLOW MEASUREMENTS IN AIR AND WATER, PARTICULARY COASTAL WATERS AND THE MARINE ATMOSPHERIC BOUNDARY LAYER. THE DLDV/SP, BASED ON A FIELD-PROVEN DLDV FOR OCEAN DEPLOYMENT UNDER ICE FLOWS, WILL BE DESIGNED FOR ON-AXIS BACKSCATTER OPERATION. IN A PULSED MODE, THE DIODE LASER WILL GENERATE INSTANTANEOUS LASER POWER IN TH ...

Achieving desired bondline temperatures is critical to ensuring proper wetting, flow and cure when repairing composite structures. Under this multi-phase SBIR project a novel method for measuring/managing cure temperature in the bondline is being pursued based on patented amorphous microwire temperature sensors that are placed permanently within the bondline and read remotely via low-frequency ele ...

The focus of this research and development effort is the maturation of a small-displacement internal combustion (IC) engine with reliable, on-board, in-flight, start/re-start capabilities specifically targeting compressed carriage sUAS aerial vehicles that are remotely deployed.The advantage of integrating of IC engines into these platforms is a significant increase in range and endurance expandin ...
