A method for detecting disbonds using transient thermography is proposed. Novel excitation methods promise to provide a sensitive technique for detecting disbonds in aluminum tongue and groove structures. The instrument resulting from the proposed research and development effort will be low cost and portable to insure that it can be easily deployed to repair and inspection depots.

Radiance proposes to develop, upgrade, and enhance the Virtual Combat Laboratory’s (VCL) high-fidelity threat models to support the development of network-centric warfare connectivity architectures and technologies for aircraft. In addition, Radiance proposes to upgrade the current network monitoring and recording capabilities of the VCL to allow analysis of sensors, next-generation communicatio ...

The objective of this proposed effort is to research, develop and demonstrate a prototype of a multi-mode low profile sensor that will detect a wide range of reverse engineering attacks. This will be accomplished by creating a multi-layered sensor architecture into which a myriad of AT Sensors can be inserted. This effort uses the multi-layered approach to employ two complementary AT sensor tech ...

The objective of this research is to develop and demonstrate a nanoparticle-loaded thin film that can detect and discriminate X-ray and focused ion beam (FIB) radiation for tamper protection. The film can be micro-patterned directly onto electronic packages as an anti-tamper (AT) device. Research will include illuminating the film with X-ray or FIB radiation that will produce flashes of light whi ...

The need for self-managing networks is readily apparent. As network systems become more vital to the organizational mission, they grow larger, faster, more complex, and more difficult to protect. However, developing a technology for effective self-management is challenging. The solution must have the ability to plan and carry out transitions from actual to desired state of the network within a ...

To address the critical issue of software defects and vulnerabilities in code, be it C, C++, Java or Visual Basic, Sentar proposes the Digital Microscope (DM). The DM simulates a native running environment in which a binary code can be encapsulated, analyzed, and tested for malefactor influence, as well as poor coding practices. The design of the DM will allow, for example, the testing of code thr ...

Capabilities of large-scale software intensive systems such as those of interest to the Software Producibility Initiative are built incrementally within the overarching infrastructure. This requires frequent updates/extensions to integrate processes and to ensure expedient, fault tolerant, secure and robust operations. The potentially widespread impact made by incorporation of new capabilities cou ...

The Phase I research has established the feasibility of achieving substantial reductions in the dynamic response of wind tunnel sting mounts using passive damping techniques. Of the three principal passive damping concepts evaluated, the Hub Damper Unit (HDU) concept was determined to be the most suitable, and further development of this is planned in the Phase II research program. The primary s ...

Aeroservoelastic analysis has achieved a high degree of maturity, covering all flight phases, while the important ground contact phase is not developed to the same degree of fidelity. This requires modeling the landing gear and its associated systems to an improved level of detail, to be interfaced with the aircraft aeroservoelastic models, enabling dynamic interactions and loads to be analysed w ...
