Characterizing turbine engine rotor vibratory characteristics is becoming increasingly complex with the introduction of advance technologies, such as integrally bladed rotors (IBR), low aspect ratio airfoils, 3-D aerodynamic computational fluid dynamics (CFD) design blades, and advance materials. The analysis and measurement techniques used to evaluate the vibratory characteristics has also advan ...

Aircraft and cruise missile mission and route planning is a time-consuming and inflexible operation today. This effort proposes to use cooperative-competitive neural networks and Hierarchical Scene Structures for multisource and multisensor data fusion procedures that will build flexible data structures. These structures can then be accessed by a route planning neural network to generate coordinat ...

THE ARS-9 PRIMARY SURVEILLANCE RADAR HAS A DIGITAL OUTPUT INSTEAD OF THE ANALOG OUTPUT OF IT'S PREDECESSORS. THE COMPUTER AND DISPLAYS EQUIPMENT FOR NAVAL AIR TRAFFIC CONTROL COMPUTER NEEDS DIFFERENT DATA THAN THE ASR-9, NOW SUPPLIES. AN INTERFACE WILL BE DESIGNED THAT WILL TAKE THE OUTPUT OF THE ASR-9 EITHER FROM MODEM OR FIBER OPTICK LINK OR MICROWAVE LINK OR ON-SITE ATTACHMENT AND CONVERT FOR T ...

Accurate Automation Corporation (AAC) proposes a unique Unmanned Aerial Vehicle Launch and Recovery system for a U.S. Navy Unmanned Surface Vessel (USV). AAC proposes an innovative concept for repeatedly stowing, launching, guiding, recovering, and restoring one or more UAVs without sacrificing operational tempo. While UAV’s have been used extensively in-theater to support the troops, USVs are ...

In this phase I proposal GTL will leverage its experience in innovative composite tank design and production for spacecraft and propulsion systems in order to produce a high-performance composite torpedo fuel tank. GTL’s methods reduce tank mass by 60-75% over the state-of-the-art rocket systems. These rocket propellant tanks operate with corrosive fuels in harsh environments, have metal-to-comp ...

Incorporation of cleavage microcracks on otherwise crack free material is a new approach used in the fabrication of some microelectonics devices. This proposal describes the development of a new computer controlled microindenter system for the farication of microcracks on a crystalline substrate. System capabilities will include the introduction of two simultaneous Vickers indentations at precise ...

Advanced computational tools capable of predicting the effects of fatigue corrosion on new alloys are needed to design the aircraft fleet of the future. The corrosion process is complex involving a combination of factors including material chemistry, processing history, microstructure, and operational environment. During the Phase I, VEXTEC demonstrated physics based corrosion pit nucleation model ...

The proposed effort will create software that will serve as an integration tool to link the results of the material degradation research due to corrosion fatigue into a usable structural analysis tool. Fatigue failure due to corrosion is a multi-disciplinary, multi-scale problem that needs to integrate several mechanisms for accurate simulation of the damage state and better prediction of failure ...

Technology for extending the life of fielded systems offers the potential for significant savings in total ownership costs. On-board monitoring combined with physics-based analysis will instill increased confidence in prediction of remaining useful life. The prime contractor OEM is currently working on methodology for JSF 1st stage fan blade prognosis using deterministic methods. However determini ...
