The objective is to show that the performance requirements and costs of GPS/IMU implementations of attitude and sightline systems are substantially lower than those of conventional non- GPS aided designs. The errors of integrated GPS/IMU attitude and sightline stabilization systems are determined by simulations of these systems using complete mathematical models of IMUs and GPS receivers. The GPS ...

The growing reliance on wireless electronic systems presents us with a need for new diversity antennas for civilian and military platforms. These antennas must take account of platform curvature, material treatments and nearby interactions, all of which affect the antenna performance. To support the development and design of these antennas, a new generation of analysis is required which retains ...

Warhead design calculations and weapons effectiveness estimates require a methodology to predict structural response and the associated damage to air targets from reactive munitions. The objectives for the proposed Phase I study effort are to develop candidate launch conditioning, reaction initiation and reaction rate methodology, to incorporate existing ballistic, blast and quasi-static pres ...

In spite of their high speed and precision, contemporary computing platforms fail to deliver the computational density required for real- time image processing towards the realization of truly intelligent and autonomous behavior in today's weapons systems and computers. And yet the simplest of living systems are able to perceive and interpret their environment effortlessly, using only a ...

Society is currently plagued by the disposal of post consumer plasti c waste products which represent 30% by volume of the National solid waste stream. The Navy has particular problems when a vessel is at sea with several thousand men consuming foods and beverages contained in plastic. The plastic waste volume becomes both a sanitation and storage problem. At sea, dumping is no longer permit ...

A novel Separate Process Diesel (SPD) engine design with an unconventional gas cycle is presented which uses three interdependent chambers to process the working fluid; a piston compressor, a rotating combustor unit and a piston expander. The SPD cycle outperforms current lightweight high power density engines primarily due to its increased mass induction per cycle. The SPD compressor cylin ...

The Virtual Engineering firm is a reality, with a team of scientists and engineers scattered at home sites working together to solve tough engineering problems. This SBIR will perform research and development to provide collaborative system engineering tools for network engineering projects. We will explore new directions for collaborative systems engineering (SE) that enable distributed req ...

Particle Size Distributions are fundamental to any study of aerosols. If chemical species in the aerosol size ranges are to be determined, the cascade impactor is the instrument of choice. Research quality cascade impactors are commercially available but are not optimized for low weight and low power use. Aircraft-mounted cascade impactors to collect samples for size-resolved chemical distribution ...

This proposal is for a feasibility study to develop an interface system capable of presenting data from multiple sources and of varying types to operator in an easy, clear and unambiguous manner. The proposed standar interface system will be based on the Multi-dimensional, User-oriented Synthetic Environment (UuSE). UuSE has been developed at DOE's Sandia National Laboratories, Albuquerque, NM, a ...
