The objective of the proposal is to reduce the cost of fabrication of sapphire optical hyper-hemispheres for submarine masts. Due to the nature of sapphire, deriving complex geometries from grown boules using current conventional fabrication techniques is one of the major contributors to cost. Removing excess material requires long diamond tool grinding cycles. New advances in ultrasonic technolog ...

A system to covertly communicate in underwater acoustic shallow water environment for Naval applications is described. Techniques for clandescent and directional communication are evaluated. Broadband underwater communications are developed.

Response Technologies (RT) seeks to determine the technical feasibility of a: scalable, economical, repeatable, and optimized polymeric matrix (RTPM). RTPM shall have universal fuel compatibility and could replace incumbent reticulated polyurethane foams in explosion suppression fuel tanks. RT’s process utilizes additive manufacturing to produce polymeric parts from 0.5 to 20 PCF. This will be f ...

Propel LLC will develop novel and innovative low cost fire resistant (FR) polymers and yarns. These FR materials will be spun with cotton, and new innovative low cost FR NYCO textiles produced. The performance objective will be to meet the physical performance requirements for the USMCs Marine Corps Combat Utility Uniform, with FR properties based on those for the USMCs Fire Resistant Organization ...

This project is the development of a single crystal underwater acoustic modem transducer for Unmanned Underwater Vehicles (UUV) which is compact in size, operates at low to moderately low center frequencies, in a broad band frequency range to accommodate state-of-the-art binary, FSK and spread spectrum signaling schemes that promote covertness. The device exploits the high coupling coefficient an ...

Underwater acoustic modeling plays an essential role in the design, development, test, and operation of sonar systems. Active acoustic clutter can increase the sonar false alert rate or equivalently decrease the probability of detection/classification, and is a key issue in the development and utility of active sonar systems. The ability to predict reverberation and clutter is inseparably tied to ...

TAC PROPOSES TO CONDUCT A STUDY TO EVALUATE THE COMPARATIVE EFFECTIVENESS OF VARIOUS FORWARD-LOOKING AUTONOMOUS SENSORS AND ALGORITHMS FOR TLAM-C. THE CURRENT TLAM-C USES A TERRAIN MAPPING RADAR ALTIMETER AND CORRELATES THE SENSED AREA AT KEY WAYPOINTS WITH A STORED DIGITAL REPRESENTATION OF THE TERRAIN AREA AT THE WAYPOINTS TO PROVIDE MID-COURSE AND TERMINAL GUIDANCE CORRECTION TO THE INERTIAL NA ...
