THE PROPOSED PHASE I EFFORT CONSISTS OF ANALYSIS AND EVALUATION OF TECHNIQUES FOR MEASUREMENT OF ACOUSTIC SENSOR POSITIONS IN LONG TOWEDARRAYS FOR USE IN REDUCING PERFORMANCE DEGRADATIONS DUE TO ARRAY MOTIONS AND DISTORTION. PRESENT AND FUTURE ARRAY DESIGNS AND OPERATING ENVIRONMENTS WILL BE CONSIDERED, WITH SPECIFIC ATTENTION TO NONACOUSTIC SENSOR SUITES AND CAPABILITIES. A SURVEY OF SHAPE ESTIMA ...

Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

An operational requirement is projected for an inexpensive, mobile, submarine acoustic countermeasure capability. A significant tactical advantage is gained by putting as much distance as possible between the submarine (launch platform) and the mobile countermeasure. An additional advantage is gained if the submarine has the ability to place the ADC between itself and the torpedo threat. Adding ...

1This proposal describes a program to design a regenerable gas generator system which can be used safely aboard submarines. We propose to investigate a number of possible techniques using all liquid, all solid or combined liquid/solid fuel/oxidizer combinations. One candidate system which looks very attractive would use hydroxyl-ammonium-nitrate to react with surplus deisel fuel which is already o ...

The design of vertically firing gun is merely a simplified version of a normal large caliber gun system. The fixed orientation of the weapon simplifies the ammunition feed and loading system as well as eliminating the need for an equilibration The challenges of the current proposed system are presented by rate of fire, vertical height limitation, structural required to accomodate high loads o ...

The goal of this program is to develop and implement optimal spectral signature detection techniques which provide automated detection and identification of materials in hyperspectral image sequences. The requirement to detect, identify and discriminate materials is a common theme in many applications of imaging spectrometry. In general, materials of interest are often smaller than the spa ...

Existing UHF SATCOM antennas are unsuitable for use on high performance tactical aircraft due to their size, weight, and/or aerodynamics. The proposed efort seeks to fill the Navy's need for conformal or minimal protrusion SATCOM antennas for their tactical aircraft. Two breadboard antennas, one broadband and one tunable, would be developed and demonstrated. The broadband element would be no large ...

Audiodontics, Inc., under the support and cooperation of the University of Maryland, has recently developed a hearing aid called the Intraoral Audio Transducer System (IATS). The IATS uses a miniature actuator of Terfenol-D coupled to a tooth to provide bone conduction sound. Terfenol-D permits high power transduction with very low voltage and thus a safe system for installation inside the mouth ...
