Ceramic matrix composites (CMCs) are being targeted for many military and commercial applications due to their light weight and high temperature stability. Their deployment is hampered by limited environmental durability. The Navy, under the JSF program, is evaluating a high performance CMC for an exhaust nozzle component. The CMC suffers from environmental degradation, primarily due to hot cor ...

: The development of cost-effective manufacturing technique for PMN-PT based piezoelectric single crystals with enhanced capabilities is critical to the achievement of the new generation of acoustic transduction devices. In Phase I, feasibility of the novel technique was demonstrated. The objective of this research project is to continue development of reducing the manufacturing costs for large-si ...

HMC's objective is to conduct an accelerated 3 month research and development effort to investigate the feasibility of applying the Lorentz Force to the creation of an electromagnetic armor system that will provide both heavy and light armored military vehicles as well as fixed armaments with an effective defense against multiple, and otherwise lethal RPG attacks.

The Navy has a critical need to measure the temperature at critical areas on the inner bore surfaces of large guns in order to insure appropriate action is taken in case of misfire. In this Phase I proposal we develop and validate an ultrasonic sensor system concept that is capable of measuring temperatures near the barrel inner diameter at critical locations. The method is based on tomographic ...

The Navy has a critical need to measure temperatures at critical areas on the inner bore surfaces of large guns in order to insure appropriate action is taken in case of a misfire. In the case of a misfire, the gun crew must know the bore surface temperature in order to decide if they have time to safely remove the ammunition before enough heat has transferred from the hot barrel, possibly initi ...

The fabrication of ceramic matrix composites is a multi-step process requiring careful monitoring and control at each step in the processing cycle. Consistent, high quality components can only be reliably reproduced if a firm foundation is provided by initially insuring the uniformity and consistency of the reinforcing yarns. Although considerable effort has been invested in developing NDE suita ...

In this effort a high temperature inorganic polymer binder will be combined with quartz fabric layers to construct radomes that will be transparent at millimeter wavelengths and act as an electrical conductor at low frequencies. Electrical performance and environmental performance will be demonstrated during this effort with the use of test coupons and full sized radomes. Lindsey Associates freq ...

The objective is to develop the design and manufacturing procedures for a rugged low cost non-dielectric missile radome that can be manufactured using simple material and process techniques. The focus will be on an electrically thick metal radome with array of holes or slots that are filled with dielectric plugs. Coverings will be designed for impedance matching and thermal considerations. The ...

The US Navy has an immediate and compelling need for a handheld, battery powered, fiber optic power meter with a remote optical detector. Existing handheld meters have the optical detector mounted on the main unit. Such meters often do not fit in the tight spaces found in ships, planes, and other vehicles. A novel fiber optic power meter design with a remote optical detector probe is proposed for ...

This proposal is aimed at further improving the design of quantum cascade lasers for ambient temperature free-space communication in the mid-infrared (4< lambda
