The success of this novel combustible case material and design will enable a technology transition to PEO Ammunition, delivering lightweight small caliber ammunition to the U. By reducing the ammunition weight, soldiers will be able to carry stronger armor protection and additional gear without compromising their mobility, thus achieving tactical objectives with improved soldier survivability. The novelty of this topic is that it addresses a long term need in small caliber munitions through new and novel material technologies. While felted fiber and even celluloid based combustible cartridge cases have been implemented for large caliber propulsion systems, there has been little work done to transition to small caliber munitions, due to the issues described above.

This SBIR project provides a unique opportunity to study both novel combustible case materials for small caliber ammunition but also the design of the ammunition, in order to provide the soldier with a lightweight next generation system solution. No residue should be left behind after combustion. Conduct dynamic finite element analysis simulations to validate the interior ballistic performance of the proposed combustible cartridge case designs.

PATR, Vol. III, p. II, Jun , p. Such a GPS-independent local coordinate referencing system can then be used by fixed and mobile platforms as well as soldier handheld devices, for guidance and control of smart and guided projectiles, for target designation, and for other applications in which GPS is currently used. Such local coordinate referencing systems are highly desirable to use methods and devices that allow them to be networked with adjacent local coordinate referencing systems as well as being adaptive to accommodate input from multiple sources and those provided on UAVs, UGVs, forward observer, and other land and air platforms.

It is also highly desirable that the local coordinate referencing system provide full orientation as well as full position information onboard a moving or fixed object. The establishment of such a full position and orientation referencing system is highly advantageous since it can enable smart munitions, weapon platforms, vehicles and warfighter to have a common accurate, reliable and secure position as well as orientation referencing system, and since static or dynamic target position and heading is also indicated in the same referencing system, the target intercept error is also minimized.

The proposed local coordinate referencing system must be robust, relatively small and low power, rugged, and capable of being deployed very quickly and automatically network all the provided referencing sources. Each proposed system must be capable of providing a local coordinate referencing system over a 30 km and preferably 50 km range with the capability of being networked with adjacent systems to extend the range. The system must be capable of providing full position which includes elevation accuracy of better than 2 m and sub-degree full orientation accuracy.

The proposals must address issues related to reducing the probability of detection and jamming of the system referencing sources. Using realistic modeling and simulation, determine the potential performance of the system, including its position and orientation measurement accuracy, range, power requirement, and line-of-sight and non-line-of-sight performance.

In the military related areas, the developed position and orientation referencing system enable smart munitions, weapon platforms, vehicles, forward observer and warfighter to have a common accurate, reliable and secure position as well as orientation referencing system. The referencing system can then be used for guidance and control of all smart munitions, missiles and guided bombs as well ground and airborne weapon platforms with minimal error due to the use of a single position and orientation referencing system. The developed position and orientation referencing system also has homeland security and commercial applications for guidance and control systems of various, robotic systems, particularly those used for remote operation in hazardous environments, which may be encountered in homeland defense, and for almost all mobile robotic applications used in the industry for materials handling and other similar applications.

Commercial applications also include material handling equipment such as cranes; loading equipment, particularly in the sea; and industrial equipment used in assembly, welding, inspection, and other similar operations.

Pereira, Michael Mattice, Robert C. Unmanned Aerial Systems UAS could potentially provide real-time military reconnaissance, fire and rescue, law enforcement, and other first-responders with important new ways to enhance mission effectiveness and reduce operational costs.

While the small Unmanned Aerial Vehicles needed for such missions are now available at reasonable cost, the navigational and control systems and associated software required to conduct such coordinated, precision autonomous operations in low altitude urban and suburban airspaces are not yet available.

This is because current state-of-the-art systems rely heavily on the U.

Software tools and algorithmic techniques not dependent on GPS are necessary for UAS navigation in the urban-suburban airspace. One such technique is three dimensional 3D map-matching. Early 2. Moreover, commodity sensors are now available which generate real-time point-clouds that could potentially be matched to the pre-acquired 3D geospatial data to provide rapid, precise localization in many GPS denied environments.

However, two problems have slowed the evolution of efficient 3D map-match solutions. First, because the 3D geospatial data sets are so large, it can be difficult to transmit and maintain them over bandwidth and latency constrained networks using conventional data delivery approaches. Second, processing of these massive 3D datasets by 3D map-matching algorithms can be very inefficient because the matching algorithm is typically forced to process a large amount of occluded data that is irrelevant to the immediate 3D map-match localization solution.

This is especially true in densely occluded natural terrains or within the urban canyon. The ultimate goal is the design of algorithmic techniques resulting in a software system that can overcome the delivery and processing problems of 3D map-matching and efficiently stream 3D reconnaissance data over constrained networks and use this data to perform precise localization for UAS to navigate in suburban and urban terrains. This software system should be able to encode these massive 3D data sets or some subset sufficiently necessary for navigation purposes, including geometric visibility, of previously obtained 3D maps of the urban terrain and efficiently transmit this data to the UAS navigational system in real time.

Then the system should be able to match the current sensor-derived ground truth obtained by the UAS sensors to the streamed 3D representation, also in real time, to enable instant, on-demand access to timely and detailed 3D data for analysis, mission planning, mission rehearsal, and battle damage assessment.

Besides enhancing military operations, such a system would have a wide variety of civilian uses such as fire and rescue, law enforcement, and other first-responder situations making it highly viable as a commercial product. Such software could easily be licensed for both military and civilian purposes or marketed as a single software package. This can be accomplished by 1 investigating and recommending or developing efficient techniques to stream massive 3D data sets of previously obtained 3D maps of the urban terrain to the UAS navigational system in real time and 2 investigating and recommending or developing appropriate techniques to match sensor-derived ground truth to the streamed 3D representation, also in real time.

Then conduct a proof-of-concept simulation of each of the above. This can be accomplished by 1 implementing the technique from Phase I to stream massive 3D data sets of previously obtained 3D maps of the urban terrain to the UAS navigational system in real time, 2 implementing the technique from Phase I to match sensor-derived ground truth to the streamed 3D representation, also in real time, and 3 incorporating the above into a single software system.

In addition, a comprehensive set of software documentation will be prepared and made available for users and a long-term program for maintenance and subsequent improvement of the software will be created.

By combining sensor-based, data driven navigation and efficient continuous remapping, this effort could realize a scalable, sustainable, and deliverable representation of any environment and enable important new capabilities in autonomous navigation and intelligent tactical maneuvering. Consequently, this effort could increase the speed and reduce the cost of processing, exploiting, and disseminating 3D geospatial data for both military and civilian operations in urban and suburban settings such as reconnaissance, fire and rescue, law enforcement, and other first-responder activities.

The firm will follow-up on appropriate marketing and licensing opportunities from collaborations and contacts developed during earlier phases. The company will set up a support service for both existing and new users capable of addressing installation issues and correcting bugs.

This will include creating a web site with the latest news, FAQs, user' forum, etc. Agarwal and R. Sharathkumar, "Streaming algorithms for extent problems in high dimensions," Proc. Poullis and S. Huang and S. Conference, The mission duration of current RAS is limited by how much fuel or batteries they can carry. There is no built-in fuel generation in current design; consequently, the typical operation duration for a single mission is limited to about 20 to 30 minutes.

As noted in the position paper from Maneuver Center of Excellence [1], the Army needs new technology to improve the sustainment of future combat vehicle. To address this challenge we need new compact energy harvesting fuel generators that generate high energy density fuel-like chemicals from indigenous biomass such as lignocellulosic biomass.

The main technical challenges are that this new compact generator needs to be transportable and be able to convert various feedstock composition with different moisture content at a fast reaction rate.

To address these challenges, Army seeks innovative approach to upgrade indigenous biomass to energy-dense chemical. There are several approaches that are previously investigated, including pyrolysis, deoxygenation, and hydrodecarboxylation [2]. These prior approaches were relevant for industrial scale. But the Army needs new materials and processes that would be relevant for RAS that do not create an additional logistics tail problem of high purity hydrogen and other consumables.

The small business, in their proposal, will describe approaches of their own choosing to solve the problems.
