The new joint mission scenarios and stealth interdiction objectives for the U.S. Navy have resulted in the need for improved sensor systems for operations in the littoral environment. A High Frequency Towed Array (HFRA) sonar system, operating in the same frequency band as hull mounted systems, provides better detection, classification, and localization capabilities,and reduces ship maneuverabilit ...

Autonomous unmanned systems require provisions for fault detection and handling. Multiply-redundant schemes typically used in aerospace applications are prohibitively expensive for general applications, especially where low cost or small size are critical. A new strategy, proposed herein, offers the potential for low-cost fault-tolerant control of paramter-dependent systems that will be useful in ...

A Variable Reluctance Machine - Electric Start System for an advanced ship propulsion turbine engine is offered as a replacement to the existing air turbine start system. The VRM technology is capable of producing the required starting torques for the turbine engine, while operating at lower nominal speeds. This will significantly improve start system reliability. The simple design, intrins ...

Radar-guided weapons can be confounded by a number of factors, including clutter, jamming, target glint, and engine modulation. Missile/target encounter simulations, if they are to test a homing systems weak points, must incorporate these effects. We propose to investigate the electromagnetic (EM) modeling requirements for a complete radar-guided weapon system simulator. Specifically, in the Pha ...

The work proposed for Phase I has been formulated with the objective of defining a basis for developing and fielding a computer based tool for selecting and performing trade studies on multimedia. The basis will be drawn from theory, research, and successful cases of multimedia instruction directly related to Navy applications. The proposed Phase I effort will focus on specification, ground ...

A meaningful computer simulation effort in the area of high-power machinery systems could have a major impact upon the cost of developing these systems. It is proposed, in this Phase 1, to develop modular, detailed and reduced-order digital computer simulations for an example high-power machinery system. Implementing these types of simulations using standard techniques may not be sufficiently inno ...

JDAM and similar DGPS based military applications impose tight error budgets on PPS receivers. Validation of these capabilities proves challenging with traditional ground-based and GPS-based reference systems. Available carrier-phase DGPS systems have great potential as reference systems, but their response to signal blockage and high dynamics is poor. Simple cascaded IMU formulations are inade ...

The jet vane is located in the aft region of the missile propulsion system nozzle and is used as a Thrust Vector Control device. In order for the jet vane to function properly, it must be designed to survive the thermal and erosive environment of the propulsion system gas stream. An improved jet vane is one that is lighter in weight and smaller in size than the current design but does not compromi ...

Advanced Technologies Group, Inc. proposes a Solid-state, Lightweight, Active-balance-system, Powered-by-light, (SLAP). The SLAP balancer will reduce or eliminate drive shaft vibrations caused by rotational dynamics of the Joint Strike Fighter (JSF) lift fan drive shaft. Reduced shaft vibration will prevent drive shaft maintenance and improve support bearing life while reducing lift fan clutch w ...

Under this program, an evaluation will be performed to select the optimum electric power generation package to meet electrical output requirements within the confines of the propulsion system architecture - based on the results of the Phase I SBIR. Additionally, system configuration and integration issues will be addressed in an effort to quantify the following: · Document the prime power gener ...
