Current and future Army helicopter missions require close support of combat operations, resulting in exposure to enemy ground fire. Current armor systems significantly reduce the load carrying capacity of the helicopter thereby reducing its mission effectiveness. New innovative technologies to significantly reduce the areal density of armor is needed to make significant enhancements to survivabili ...

The ability to characterize optical fiber coils with long lengths of fiber (at least one kilometer) is crucial for the characterization and testing of interferometric fiber optic gyroscope systems. An important characteristic of the fiber sensing coil which directly impacts system performance parameters such as bias stability is the amplitude and spatial location of spurious polarization cross-co ...

TO CREATE A DOPPLER IMAGER OF A TARGET, SUCH AS A SATELLITE, WITH A LASER RADAR, IT IS NECESSARY TO HAVE A LASER CAPABLE OF CREATING A SUITABLE. DOPPLER IMAGE RESOLUTION IS DIRECTLY RELATED TO THE LENGTH OF THE LASER PULSE (THE AMOUNT OF THE TARGET ILLUMINATED IN AN INSTANT OF TIME), AND THE REQUIRED SPACING BETWEEN PULSES IS RELATED TO THE MAXIMUM TARGET SIZE. THIS PROPOSAL ADDRESSES A METHOD OF ...

AZ Technology proposes to design and test an innovative polymer coating system and demonstrate prototype production of a moisture/gas barrier coating to effectively eliminate composite sabot moisture related expansion. The Army has identified a need to reduce expansion of epoxy composite materials used in experimental artillery ammunition sabots. We propose to use our expertise in coating design ...

Production of 3D terrain databases for visualization requires resolving tradeoffs between a complex set of constraints: time, resources, accuracy, resolution, hardware, limitations, etc. The relationship between these parameters and the quality of the final database for most applications is not well understood. There are few tools to measure quality and there is little understanding of the impac ...

Recent CFDRC and Los Alamos National Lab CRADA research activity has demonstrated 100% JTAGG fuel injector ignition reliability at fuel tesperatures approaching -10 F using precisely controlled multiple pulse formatting of a single 150 mj laser discharge. This level of performance is achievable with minimal packaging complexity using diode pumped Nd:YAG lasers and demonstrated fiber optics/window ...

Development of a software system incorporating accurate transient an simulations coupled with advanced valve control logic is proposed to aid in the design and analysis of axial pintle valve systems for low cost tactical motors. Due to strong current commercial software capability and similar pintle valve control technology, CFDRC will be able to draw on existing software to: perform the transien ...

The demonstration of CI engine injector ignition using multiple laser energy pulsing at cold soak conditions approaching -40F is proposed. This level of ignition performance will be demonstrated using a 150 mj Nd:YAG laser, low cost fiber optics, and quartz windows to minimize cost and packaging. Specific Phase I research includes: 1) Experimental quantification of optimally pulsed laser energy, ...
