ACIT will design and demonstrate a remotely addressed crack/flaw detection system for composite materials. It will consist of a passive embedded sensor and a handheld portable detector, operating on the principle of the coupling of the LC tank circuit withthe behavior of a strain sensitive resistor. This system uses well known principles of an electronic circuit with carefully balanced forces of ...

The objective of the Phase II research is to utilize the lessons learned from the Phase I risk reduction work to develop a prototype CAD-programmable environment for the development of condition-based maintenance systems for rotorcraft. This developmentenvironment features a CAD scenario modeler for constructing, via click n' drag modeling, fault-to-failure damage models which can account for the ...

Due to the success of the hybrid lidar-radar approach for improving the performance of underwater optical imaging systems, the approach of this project is to apply this technique to atmospheric laser ranging and identification systems, such as ballisticmissile detection systems. AMPAC proposes to fully understand how to model the propagation of a laser beam through various types of adverse weathe ...

There is a demand for enhanced performance gyros used in advanced inertial reference units (aIRUs) required in Space Based Laser systems and space based surveillance systems. The current high performance gyros are marginal in meeting the SBL aIRUperformance requirements and are very expensive. Applied Technology Associates (ATA) proposes to develop a breakthrough angular rate gyroscope that has ...

Applied Technology Associates (ATA) proposes to introduce a high-accuracy, inexpensive, relative position sensor (HARPS), based on shearing of EU magnetic core pieces. This new technology provides potential significant benefits for achieving a lightweight,high-precision inertial reference unit (IRU). The proposed HARP sensor will integrate technologies of low-noise differential transformer sensors ...

Applied Technology Associates (ATA) proposes to introduce a small, inexpensive, dual-function inertial angle measurement and control device based upon magnetohydrodynamics (MHD) technology. This new technology provides potential significant benefits forachieving a lightweight, high-precision inertial reference unit (IRU). The proposed MHD Actuator/Sensor will integrate technologies of low-noise ...

Barron Associates, Inc. (BAI) proposes an aggressive Phase I effort to develop novel adaptive, integrated guidance, control, and estimation algorithms for ballistic-missile interceptors with stringent hit-to-kill requirements. The approach combines recentadvances in nonlinear control (backstepping) and estimation methods, and leverages on-line neural network technology for rapid adaptation and ro ...

The ideal prognostic system would be generic, requiring no domain-specific knowledge for its application. The prognostic system must also perform across all operating regimes without generating an excessive number of false alarms, and must successfullydiagnose problems. The semi-empirical technique proposed herein by Barron Associates, Inc. and its academic partners at Princeton University takes a ...

We propose a software package that combines recent advances in several pattern recognition techniques, including neural networks, multivariate statistics and model-based reasoning. Results from these prognostics will be combined into a single probabilityof failure for the modeled component or subsystem of the ABL, which would be output to a simple graphical user interface (GUI). The preliminary so ...

This effort will investigate jitter reduction mechanisms for primary mirror of airborne directed energy weapons. The investigation will cover detailed modelling, implementation for active control and a subscale experiment.
