In an information-rich environment, the possibility of enhancing the decision-making processes and outcomes is closely tied to the proper and timely management and analysis of information. In a team decision making environment coopertion, communication, collaboration, shared situational awareness and mental models become critical parameters for success. Computer technology, hardware and software ...

Unsteady buffet forces excite the vertical tails of aircraft flying at high angles of attack and cause excessive stress and vibration in the tail structure. This results in increased fatigue which ultimately reduces aircraft life. It has been shown by ACX that distributed piezoceramics can significantly reduce the buffet loads on the tail structure of an F/A-18. ACX proposes to develop a simila ...

ACX proposes an innovative new process for the manufacture of smart structures using a High Velocity Oxy-Fuel (HVOF) thermal spray process. This simple, multi-step process will be capable of depositing electroded piezoceramic coatings. The coatings will be poled while still hot, reducing poling times and voltages while increasing poling efficiency. Process times will be extremely short. The pr ...

ACX proposes to develop durable and reliable conformal geometry actuator packages. These packages will have the ability to operate as linear actuators for motion control applications as well as to conform to structures with curved surfaces for applications requiring induced strain actuation. These packages provide a protective skin offering electrical isolation, and provide a means for integration ...

Active Devices proposes an innovation for energy harvesting using piezoelectric based approaches to extract energy from mechanical vibrations. This innovation consists of a piezoelectric element for energy transduction, rectifier circuits for extraction, and storage devices to store power for use by other devices. Ideal models predict that a 1" x1" x.010" piezoelectric wafer undergoing moderate ...

A new class of thin film coating materials, diamond-like nanocomposites (DLN) have been developed. These materials have a combination of properties making them an excellent choice for use as wear resistant coatings on mechanical cryogenic coolers for space applications. In particular, the reliability and maintainability of conventional mechanical coolers could be enhanced by engineering the surf ...

This Phase I project will investigate the feasibility of a submarine passive localization system which will localize and track short duration intentional and unintentional emissions from submarines and weapons. The approach combines radius of curvature ranging using time delay measurements from an array of hull mounted hydrophones with a multi hypothesis tracking algorithm for resolution of a ...

The XA2 gasoline burner is widely used by the military to meet a variety of food preparation and heating requirements in the field. Because of the trend toward an single-fuel Army vehicle fleet and away from gasoline as a general purpose fuel, a diesel/JPS fueled burner is sorely needed. A recently developed catalytic vapor generator together with the proposed metal-hydride preheater should prov ...
