Applied Technology Associates (ATA) proposes to develop a miniature, rapid, non-magnetic azimuth sensor by exploiting innovative magneto-hydrodynamic (MHD) inertial angular rate sensing technology. The proposed solution centers upon use of a spinning MHD sensor that outputs a modulated version of Earth rate and offers means of deriving true azimuth. Inertial rate sensing is employed to link the MH ...

The Navy is developing LADAR sensors for responsive Intelligence, Surveillance and Reconnaissance use where ranges to targets exceed 10km. If such a LADAR sensor is to image a target area by scanning one or several laser beams at such long ranges, high-pointing-accuracy or knowledge, over a wide operational temperature range, is required to obtain a high-quality LADAR image. A two-axis Fast Steeri ...

Management Sciences, Inc. scientists have developed Cognitive Bayesian Information Exploitation (CBNX), a revolutionary set of algorithms that apply context frames as filters to learn causal relationships needed to understand and exploit the meaning of data. We have applied the CBNX toolset to develop real time situation awareness of the health of aircraft engines, forest fires, and intelligent ma ...

A major barrier to the widespread adoption of wireless sensors for structural health monitoring is the requirement to power the network of wireless nodes. Batteries have a limited lifespan, adding significant size, weight, and costs to the wireless sensor network,and may represent a long term environmental problem. Battery maintenance can be eliminated by harvesting energy from the environment. Fo ...

Structural monitoring of Navy aircraft is of critical importance as the fleet ages. One critical area includes the control surfaces, which are subject to intense, dynamic buffet loading which can lead to structural cracking. The highly transient nature of buffet loading makes it difficult to measure using conventional sensors. We propose to solve this problem by combining a network of time-synchro ...

NumerEx proposes to collaborate with the University of Southern California (USC) to support the advanced concepts, basic science, and engineering of high repetition rate multiple barrels pulse detonation engine (PDE) technology. NumerEx will support experimental developments at both USC and the Naval Postgraduate School (NPS), and will provide a strong theoretical and computational core for the in ...

Electron beam optics codes are presently used in the design of vacuum electron devices. The goal in using codes of this type, such as MICHELLE, is to produce a sufficiently accurate design of a device that the manufacturer can build the tube based exclusively on that design. Devices with high-brightness electron beams involve non-ideal physical mechanisms that can cause non-acceptable divergence b ...

The Navy requires measurements of the wake field of helicopters in the vicinity of carrier ships to determine the safe operating envelope for the V-22 and to verify the accuracy of models obtained by computational fluid dynamics. This Phase I SBIR project will examine the feasibility of a laser-based remote sensing technique for recording three dimensional wind fields with high spatial and tempora ...

For significant advancements to occur in the implementation of ceramic matrix composites (CMCs) in aeroengine airfoil applications, silicon carbide (SiC) ceramic matrix that forms corrosion resistant scale is needed for the combustion environment. Particularly troublesome is the accelerated surface oxidation and recession that proceeds due to reaction of the native silica scale with steam in the h ...

Advanced power systems for Future Naval Capability depend on capacitor banks as the first stage of pulsed power. Significant electrical energy is necessary to support a range of applications including electromagnetic armor, electromagnetic gun and electro-mechanical aircraft launch systems. In order to ensure successful integration of these technologies, capacitors with reduced size and weight mus ...
