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 ...

The prospect of using smart material technology for active inceptor motion systems is of high interest because of the potential cost, simplicity and performance advantages over current brushless DC motor/gearbox systems. The most suitable smart material concept for accurate motion control is piezoelectric actuation, because of its precise controllability, force and bandwidth capability. Phase I ...

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 ...

THE ULTIMATE LONG-TERM OBJECTIVE OF THIS PROJECT IS TO ADAPT AND MODIFY GENERAL NETWORK'S TURNKEY PACKAGE, TOTAL SOLUTION, FOR MILITARY USE AS AN ADVANCED FACILITY TO EXPEDITE THE DESIGN AND EVALUATION OF COMMUNICATION SYSTEMS. TOTAL SOLUTION IS COMPRISED OF COMPUTER HARDWARE AND GENERAL NETWORK'S PROPRIETARY SOFTWARE. THIS SOFTWARE IS AN INNOVATIVE, MODULARIZED, INTERACTIVE GRAPHICS SYSTEM DEVELO ...

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 ...

Infinia Corporation proposes a demonstration of an operable lightweight Stirling Convertor Assembly (SCA) coupled to a JP-8 burner, which delivers both 2.5 kWe at 28VDC and 8.5 kWt of usable heat. The SCA and burner form the heart of the Stirling Tactical Cogeneration System (STaCS) conceptualized in Phase I, and their combined performance will enable the STaCS to deliver a minimum 2.5 kWe net out ...

Small Business Innovative Research (SBIR) N101-004, Air Anti-Submarine Warfare Modeling and Simulation Tool, was issued to determine the feasibility of developing an Anti-Submarine Warfare (ASW) Modeling and Simulation (M&S) tool to bridge the current gap between engineering and campaign-level tools. For this Subsequent Phase II, Sonalysts proposes to develop a FDECO Test Range Simulator (TRS) bas ...

Under SBIR Topic N04-218, Applied Physical Sciences Corp. (APS) developed and demonstrated candidate modifications to the existing DD(X) Integrated Undersea Warfare System’s High Frequency (IUWS-HF) bow sonar signal processor that would improve the sonar’s mine-hunting capabilities in refractive, multipath environments. In Phase I, we derived a localization algorithm that correlates measured ...

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 ...
