THE FAILURE CRITERIA PRESENTLY USED FOR PREDICTION OF THE ULTIMATE STRENGTH OF A COMPOSITE MATERIAL ARE BASED UPON THE ASSUMPTION THAT THE COMPOSITE BEHAVES AS AN IDEAL ORTHOTROPIC MATERIAL. THIS IDEALIZATION OF COMPOSITE MATERIALS IS INCONSISTENT WITH THE WAY BRITTLE COMPOSITE MATERIALS FAIL. SINCE FAILURE GENERALLY BEGINS AT A SMALL CRACK OR VOID A FAILUTE CRITERIA BASED UPON A CRITICAL FLAW SIZ ...

The speed at which an attack is detected is a critical trigger for all responses to follow. The accurate determination of the type of attack will determine the type of emergency personnel and response needed. The location will determine the target response area as well as determine by proximity which of the responders that are available can be first on the scene. Therefore, a system that can do th ...

THIS PAPER PRESENTS A NEW APPROACH TO THE DESIGN OF A SELF-CONTAINED UNDERWATER DATA ACQUISITION SYSTEM (UDAS) BASED ON A GENERAL-PURPOSE DIGITAL SIGNAL PROCESSING (DSP) ARCHITECTURE. THE PROPOSED ARCHITECTURE USES A HIGH-PERFORMANCE MILITARY STANDARD SINGLE-CHIP MICROPROCESSOR AS A SYSTEM CONTROLLER. WHEREAS EXISTING SYSTEMS USE SPECIAL-PURPOSE HARDWARE DEDICATED TO SIGNAL PROCESSING FUNCTIONS, I ...

MULTISPECTRAL ANALYSIS TECHNIQUES PERMIT ANALYSIS OF NONLINEARITIES GIVING RISE TO CERTAIN BROADBAND SIGNALS. THE ADVANTAGES OF THIS TECHNIQUE OVER LINEAR METHODS ARE DETAILED.

A COMBINED EXPERIMENTAL AND ANALYTICAL STUDY IS PLANNED TO DEVELOP ADVANCED COMPOSITE PIPING SYSTEMS. DUAL WALL PIPE WILL BE DEVELOPED AND TESTED FOR IMPROVED IMPACT RESISTANCE AND TOUGHNESS. EPOXY AND POLYESTER RESINS WILL BE USED IN COMPOSITE PIPE SECTIONS AND BONDED WITH EPOXY ADHESIVES AS WELL AS WITH HEAT-SHRINKABLE ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE AND ADVANCED ELASTMERIC COUPLINGS AN ...

Nova Photonics, Inc. proposes to design, fabricate, and characterize a large aperture, narrow bandwidth spectral filter. Following successful development, the prototype filter will be delivered to the Navy for an undersea demonstration. The filter will have a wide field-of-view and a spectral resolution less than 0.2 nm with high out-of-band rejection. The unique filter design results i ...

Solid State Scientific Corporation is pleased to propose a CPP Phase II program to develop an uncooled hostile fire indication system with hostile fire identification. Algorithm concepts using bands in the visible through the (uncooled) SWIR will be explored for identifying threats and their angle of arrival while rejecting false alarm sources in clutter environments. The band pass of the narrow ...

The objective of the proposed Advanced Sensor Optimal Placement (ASOP) Planning Tool is to develop a facility for Naval planners to rapidly plan, optimize, assess, and validate tasking of sensor and communication assets to support operational missions. Phase I demonstrated the feasibility of developing an ASOP Planning Tool that can be rapidly fielded to support ISR planning. The technical objec ...

Marines must drink over a gallon of water a day to operate safely and effectively in hot climates. We propose to build field test prototype units to demonstrate innovative technology for a compact drinking water chiller. The chiller can boost water consumption by cooling an individual soldier’s drinking water to low temperatures in the hottest environments. The unit will be portable, re-usabl ...

This Phase II project proposes the innovative use of radar sensors to address limitations in non-contacting stress measurement systems (NSMS). By using radar sensors with a continuous data stream, as opposed to time of arrival from discrete sensors, continuous blade vibration measurements could be performed over a portion of the blade arc of travel. By processing the data in the frequency domain ...
