This innovation proposes the use of a thin film stratospheric balloon to lift a launch vehicle with a payload to an altitude above most of the Earth's atmosphere, then ignite the launch vehicle rocket motor. It will have the capability to carry the payload to its final destination, either into Earth orbit or to the mission design goal. This launch system will eliminate the first stage rocket thr ...

THE PROPOSED RESEARCH IS FOR DEVELOPMENT OF ABDUCTIVE AND INDUCTIVE REASONING ALGORITHMS THAT WILL AID IN THE DEVELOPMENT OF FLIGHT CONTROL SYSTEM (FCS) MAINTENANCE DIAGNOSTIC SYSTEMS AND THAT WILL OVERCOME MANY OF THE LIMITATIONS OF EXISTING DIAGNOSTIC TECHNOLOGY. A FOCUS OF THE EFFORT WILL BE THE DEVELOPMENT OF A CAPABILITY TO REASON ABOUT FSC FAULTS AT A SYSTEM LEVEL WITH UNCERTAIN INFORMATION. ...

THE OBJECTIVE OF THIS EFFORT IS TO DEMONSTRATE A PROTOTYPE CONTROLLER FOR A HOWITZER USING A HYBRID NETWORK AND PRODUCTION RULE SYSTEM. THE RESULTING ADAPTIVE CONTROLLER WILL DEMONSTRATE THE FEASIBILITY OF DEVELOPING A REVOLUTIONARY CONTROLLER CAPABLE OF ADAPTING IN A DYNAMIC ENVIRONMENT, MONITORING AND DIAGNOSING BEHAVIOR, AND PREDICTING FUTURE FAULTS AND MAINTENANCE REQUIREMENTS. ABTECH HAS DEVE ...

Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transitted or received, ie.e, one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency, nulls begin to develolp which threaten the integrity of the communication link. Experience has shown that small excusio ...

THIS IS A PROPOSAL TO PRODUCE AN ACOUSTIC ARRAY DESIGN SUITABLE FOR MAKING ACOUSTIC MEASUREMENTS OF MODEL HELICOPTERS IN A WIND TUNNEL. THIS "FEASIBILITY DESIGN" WILL DEMONSTRATE THE THEORETICAL FEASIBILITY OF SUCH A WIND TUNNEL ARRAY, AND WILL QUANTIFY THE PERFORMANCE OF SUCH AN ARRAY. THE WORK WILL INVESTIGATE THE DESIGN TRADEOFFS AVAILABLE AND WILL ESTABLISH THE COMPUTATIONAL REQUIREMENTS FOR A ...

The contractor has patented technology for a unique process that directly converts a two-dimensional acoustic disturbance, such as a wave front, into an intensity-mapped visible image in real-time without electronic circuitry; i.e., it is a direct pressure gradient imager. This device can allow a small, battery powered acoustic source to be easily located and ranged using a small flashlight sized ...

The overall objective of the proposed research is to develop bistatic detection techniques for shallow water near land warfare operations. The focus of our proposed research is to achieve detection enhancement in environments characterized by dense multipath through application of optimal detection theory coupled with accurate acoustic modeling. The first specific objective is to consider alternat ...

A NEW AND INNOVATIVE CLASS OF ADAPTIVE COMPUTATIONAL PROCEDURES IS TO BE DEVELOPED FOR THE SPECIFIC PURPOSE OF NUMERICALLY-MODELING COMPLEX FLOWS INHERENT IN ADVANCED HELICOPTER-BLADE DESIGNS. THESE PROCEDURES MAKE USE OF MATHEMATICALLY CONSISTENT ESTIMATES OF LOCAL NUMERICAL ERROR, AND AUTOMATICALLY REFINE OR UNREFINE THE MESH OR INCREASE OR DECREASE THE LOCAL SPECTRAL ORDER OF THE APPROXIMATION ...

Significant savings in system life cycle costs can be realized when common Automated Test Systems (ATS) resources are used to meet both system production and field maintenance needs. Additional cost avoidance and quality gains are the result of transferring unit under test (UUT) design data, "lessons learned" gained during manufacturing in-process and system acceptance (sell-off) testing to the ma ...
