The DoD requires new sources of eye safe, short pulse, laser radiation to enable the next generation laser radar (LADAR) seekers. Conventional eye safe laser sources using diode-pumped solid-state laser (DPSSL) and optical parametric oscillator (OPO) technologies have difficulties to meet the packaging requirements and to operate with constant pulse width at variable repetition rate. Also, the e ...

Fiber coupled mid-infrared and infrared semiconductor lasers provide potential technology for proactive infrared countermeasures systems, potentially reducing life cycle costs for these tactical military systems compared to current lasers. Research will be conducted to explore the feasibility of developing low loss infrared transmitting chalcogenide glass fiber optics. The proposed work will als ...

First generation mid-infrared lasers contribute to the prohibitively high life cycle cost of infrared countermeasures systems, precluding their broad application in helicopters. We propose to develop a fiber amplifier-based IRCM laser transmitter that will contain all optical beams within optical fiber, eliminating adjustable, discrete, optical mounts, to significantly increase the laser's MTBF. ...

Strength and durability of commonly used bonded and bolted composite-to-composite and composite-to-metal structural joints suffer from sharp geometry variations, mismatch of elastic moduli, Poisson's ratios, coefficients of thermal expansion and thermal conductivity of the adherends, altogether causing high stress concentration and premature joint failure. The proposed work introduces several nove ...

It has been well documented that the Navy's Seabasing vision for staging bases near the theater of operations calls for an extension of the distance offshore from the current two to five miles to one hundred to two hundred miles. Although the distances will be greater, response times and throughputs must remain the same or improved. This will consequently require heavy lift and high speed landin ...

The topic stated objective is the development of innovative approaches to provide in-situ hull form augmentations to the existing ships and craft to allow for increased speed without a significant reduction in payload capacity. The proposed project will accomplish this by implementing an innovative air cavity system (ACS), Bow Fairing, and propulsion changes to the LCU 1600, thereby converting it ...

The proposed research will develop a non-equilibrium plasma source for deposition of thin films on refractory materials at temperatures less then 600K. The developed source will also have the flexibility to surface treat thermally sensitive substrates without damage. Our existing non-equilibrium atmospheric plasma source will be optimized for depositing amorphous SiC and ZrO2 thermal barrier mat ...

The Air Force needs new higher productivity, higher accuracy equipment and processes for machining integral, complex aircraft airframe structures cost effectively. Structures with simply shaped pockets and straight walls can be effectively end milled using large high velocity machine tools. However, these machines cannot efficiently mill structures with integral return flanges and other complex ...

The development of a generalized moving body capability for Computational Fluid Dynamics (CFD) flow simulations of highly transient flowfields is critical to system analyses of Divert and Attitude Control Systems (DACS) for Kinetic Warheads (KWs). Testing capabilities are limited in the DACS operating regime; therefore, computational tools are essential for such analyses. The flow in the DACS its ...

Insensitive munitions (IM) design and testing for propulsion systems is hindered both by high test costs and the complexity of propellant responses to IM stimuli. Modeling and simulation tools for predictions of IM hazards are under development that characterize many of the pertinent phenomena, including damage sensitization to reaction and delayed-onset detonation. Such tools can provide many b ...
