BECAUSE OF THE COMPLEXITY OF GEOMETRY, LOADS AND MATERIAL SYSTEMS OF TURBINE BLADES, THE STRESS AND STRENGTH CHARACTERISTICS CAN NOT BE ACCURATELY PREDICTED BY EXISTING METHODS. THE COMPOSITE TURBINE BLADE STRENGTH CAPABILITIES ARE VERY MUCH DEPENDENT UPON THE CONSTITUENT MATERIAL PROPERTIES, PLY ORIENTATIONS AND STACKING SEQUENCE. THE OBJECTIVE OF THE PROPOSED STUDY IS TO DEVELOP A TECHNIQUE TO P ...

Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

THE RESEARCH WILL PROVIDE AN INVESTIGATIVE STUDY AND DEVELOPMENT OF VARIOUS ELECTRONIC COUNTERMEASURE (ECM) TECHNIQUES TO DEGRADE THE PERFORMANCE OF DIGITALLY CONTROLLED THREAT WEAPON SYSTEMS THROUGH THE DEVELOPMENT OF SOFTWARE ALGORITHMS DESIGNED TO SATURATE OR OVERLOAD THE THREAT. THE THREATS OF PRIMARY CONCERN ARE PASSIVE DETECTION/GUIDANCE SYSTEMS WHICH WILL RECEIVE SIGNALS EMITTED BY THE DETE ...

THE OBJECTIVE OF THIS EFFORT IS TO DEMONSTRATE THE EXTENT TO WHICH CERTAIN FEATURES OF THE ADA PROGRAMMING LANGUAGE CAN BE USED TO DETECT AND HANDLE HIDDEN SOFTWARE ERRORS WHICH WOULD OTHERWISE HALT PROGRAM EXECUTION. ADA'S TYPING, EXCEPTION HANDLING, AND INTERFACE CHECKIG PROVIDE THE TOOLDS FOR BUILDING SUCH ROBUTNESS INTO SOURCE CODE. THE OBJECTIVE OF THIS DEMONSTRATION IS TO SHOW HOW ROBUTNESS ...

The use of monolithic airfoil structures in static and rotating components such as one-piece integrally bladed rotors (IBR's) in military turbine engines has created an increased risk of high cycle fatigue (HCF). The Phase I SBIR studies recently demonstrated plasma sprayed hard coating concepts that show significantly greater damping than has been observed in previous investigations. Polymer-impr ...

The SBIR team proposes the continued development and enhancement of a comprehensive, robust, unified Trajectory Management System (TMS). This system features a novel trajectory design methodology integrated with an innovative on-line aerodynamic identification architecture. The trajectory design methodology employs computationally efficient algorithms yielding feasible trajectories that are robu ...

BioRobots proposes the development of a Morphing Micro Air-Land Vehicle (MMALV), capable of transforming from aerial to terrestrial locomotion, to maximize situational awareness for U.S. warfighters. Terrestrial locomotion is based upon the Mini-Whegs platform, recognized as one of the most agile micro-robots today. Aerial locomotion is based upon the University of Florida Micro Air Vehicle (UF- ...

Insuring the safety and control of littoral waters is problematic because of the difficulties of surveillance. The preferred methods of surveillance in the ocean are acoustic. In littoral waters, acoustic methods fail because noise from the surf and reflections from the shallow bottom convolute acoustic signatures beyond our capacity to discern them. Water absorbs light, reducing the effectiven ...

IT IS PROPOSED TO DEVELOP NEW OR IMPROVED ON KNOWN GRADIENT CERAMIC/ METALLIC COATINGS FOR APPLICATION ON DIESEL IRON OR STEEL PISTONS CAPABLE OF WITHSTANDING 2000 DEF F COMBUSTION TEMPERATURES AND PROVIDING SIGNIFICANT THERMAL BARRIERS. THE TREND OF DIESEL ENGINE DEVELOPMENT AND PARTICULARLY THE LOW HEAT REJECTION (ADIABATIC) ENGINES TOWARDS HIGHER PISTON HEAD TEMPERATURES REQUIRES THE USE OF THE ...
