Anti-access Area Denial (A2AD) capabilities from peer threats render many aspects of current CONOPS inadequate.For example, our manned aircraft are projected to experience unacceptable attrition against peer IADS forces.The overall system concept of collaborative teams of smaller UAVs and manned-unmanned teams shows great promise for counteracting the A2AD threats and improving the cost-exchange r ...

The inability to plan in real-time is a major reason why robot manufacturing is restricted to high-value, high-volume products, in carefully engineered factories where robots blindly repeat pre-programmed trajectories. Today, robots simply cannot generate collision-free motion on the fly. We are solving this core problem—real-time motion planning in unstructured, fluid environments and on divers ...

The DOD and robotics industry, have a critical need for a motion planning capability that is practical for real-world application of autonomous systems that perform physical motions. Current motion planning systems are too slow; they assume that the environment will be static during motion planning and execution, each of which can take on the order of seconds. Further, these systems typically gen ...

Over the past decade, GTL has developed a suite of transformational technologies that provide superior performance for reduced cost.Each of these technologies have been matured to TRL 6 and establish the technical foundation for the Advanced Cryogenic Expendable (ACE) Multi-Role Vehicle (ACE-MRV). The ACE-MRV is a high-performance expendable rocket stage that can either be launched (from the groun ...

For SAR, spatial and temporal adaptive processing (STAP) uses samples local to the cell being processed to estimate local clutter and noise statistics. If these samples are corrupted by returns from other unknown targets, the statistics are invalid and theperformance of the algorithms can be degraded. We propose to conduct a range of experiments to evaluate signal detection, statistical, multi-loo ...

Metal matrix composites (MMCs) are the proposed replacement materials for the ferromagnetic parts that exist in an outboard engine. MMCs have specific stiffness properties 2 to 4 times that of aluminum alloys, steel, and titanium, while having equal or greater specific strength. The resulting parts are extremely light weight yet robust enough to handle high strength applications typically reserv ...

THIS PROPOSAL DESCRIBES A NOVEL METHOD FOR TARGETING NOISY, HIGH-VALUE TARGETS SUCH AS ENEMY ARTILLERY, HELICOPTERS AND, PERHAPS, HEAVY VEHICLES AND GENERATORS. THE CONCEPT MAKES USE OF RELATIVELY INEXPENSIVE ACOUSTIC SENSORS WHICH CAN BE DEPLOYED IN ENEMY TERRITORY BY AIR DROP OR BY ARTILLERY. THE SYSTEM LOCATES TARGETS BY CORRELATING THE ACOUSTIC SIGNALS RECEIVED BY SEVERAL PAIRS OF SENSORS TO D ...

A HIGHLY EFFICIENT CONCEPT IS PROPOSED WHICH WILL SUBSTANTIALLY REDUCE ACOUSTIC SIGNATURES OF HELICOPTERS AND TILT ROTOR AIRCRAFT. THE CONCEPT CAN BE INCORPORATED INTO FUTURE HELICOPTER DESIGNS WITHOUT ANY OBVIOUS, WEIGHT OR PERFORMANCE PENALTIES. THE CONCEPT WILL PRODUCE REDUCTION OF SOUND RADIATION IN ALL DIRECTIONS OVER ALL FLIGHT SPEEDS WITH MINIMAL PROCESSING.

We propose here new methods for system identification and active feedback control of axial flow compressors under conditions of incipient rotating stall and surge in the presence of inlet distortions. The nonlinear Moore-Greitzer model of rotating stall, which has proven useful for both simulation of rotating stall/surge dynamics of axial compression systems and for control design studies, will b ...
