A02-231 TITLE: A Cross-Discipline Design Workstation for Future Combat Systems (FCS) and 21st Century Truck TECHNOLOGY AREAS: Ground/Sea Vehicles ACQUISITION PROGRAM: PM, CRUSADER OBJECTIVE: To research, design, prototype, and demonstrate an innovative cross-discipline design tool for Future Combat Systems (FCS) and 21st Century Truck. The design tool will simultaneously simulate and optimize infrared (IR) and visual signatures of the vehicle through the design of the vehicle’s propulsion, thermal and power management systems. DESCRIPTION: In the design of military and commercial vehicles, many technology areas impact the vehicles’ performance and cost. Optimizing the design in any of these disciplines is a sizable task. What is needed, is a tool and a process to optimize the vehicle through integrated system-level design. The process must be streamlined by focusing the design methodology on those components that the user defines as critical. In the commercial and military environments, this might mean thermal management, fuel efficiency, space claims, material costs etc. However, in both areas, detectibility also plays a role. In industry, being detectable is desired (safety), while in the military the opposite is often true (stealth). An innovative capability is desired that would allow designers to optimize thermal management, fuel efficiency, space claims, material costs, and visual and IR detectibility. While engineering level simulation tools have been in development over the years, an integrated design tool that can run on a single workstation and can *optimize* the solution across these disciplines has not. Novel approaches, such as data mining, could be used in this process. Required features of this design tool include: given a particular vehicle, multiple propulsion system designs, and multiple environmental situations, predict the potentially thousands of outcomes; out of that pool of predictions, determine the number of unique instances, a set of minimum, maximum (or worst case/best case) and average values, and the percentage of time each occurs in the pool of predicted values; the ability to conduct parametric studies across all disciplines (efficiency, cost, space, and detectibility); automatic optimization of the design based on these studies; data input and output compatible with commonly used tools such as MS EXCEL, and a library of cross-discipline templates and component models by which users can rapidly build up prototype systems. PHASE I: This phase will outline the inventive methodology (or methodologies) to be used in the optimization process as well as the specific tools that will be used to create the workstation explained in the description. Also in this phase, will be feasibility studies on integrating the individual elements. The deliverable will be a sound development plan documented using common accepted software practices. PHASE II: A prototype of the workstation tool shall be demonstrated based on the plan from Phase I. This tool shall demonstrate the capability of optimizing a vehicle design in thermal management, fuel efficiency, cost, space, and IR and Visual detectibility, starting with at least one commercial CAD package. It shall show the vehicle in situ and provide at least one metric to be used in the signature optimization process in each signature area. The tool shall be modular in nature, ensuring the ability to upgrade as individual software components mature. PHASE III DUAL USE APPLICATIONS: This tool can be used in commercial vehicle system and sub-system design. The methodology can also be extended to any application areas where cross-discipline modeling is needed, including electronics cooling, multi-channel remote sensor modeling, ventilation system design, and environmental modeling. Should this topic be successful, this workstation would be a commercial product available to all DoD agencies and their contractors who are involved in concept design. All of ground vehicle acquisition programs would take advantage of this tool. In the commercial realm, TARDEC has a CRADA with FORD in the area of thermal management. This aspect of the workstation's capabilities would be extremely useful to all of the commercial companies doing propulsion design trade-off studies.

Advanced packaging techniques such as high performance heat spreaders will be considered. This development will provide a means to reduce the size and weight of power converters and cooling systems for mobility, pulsed power and continuous power applications. This will lead to smaller and lighter electric power systems in future Army hybrid electric vehicles, such as those proposed for the hybrid-electric (HE) HMMWV, HE-BFV, CHPS, and possibly FCS. DESCRIPTION: Operation at high power density and high temperature is a means to reduce the size and weight of power converters. Studies in the CHPS Program (Combat Hybrid Power Systems) indicate that the volume of a power converter cooling system can be reduced by a factor of 5 through high temperature operation. Additional gains in system power density can be achieved by operating power modules at high frequency and high power density. Packaging development leading to improved thermal performance is essential to achieve increased power density, temperature and frequency. The packaging developed shall be useful for both silicon and silicon carbide power devices. Packaging development is needed to make use of the vast increase in operating temperature and power density that silicon carbide devices make possible. PHASE I: Contractor shall design a packaging system with improved thermal performance. Contractor may demonstrate certain components of the packaging to prove concept. Contractor shall prove thermal capabilities using accepted engineering practices. All calculations and assumptions shall be reported. Computational models of packaging shall be used to show proof of design. Deliverables include codes or scripts used in numerical analysis. Contractor shall hold a final review meeting at TACOM near the end of Phase I. PHASE II: Contractor shall fabricate and demonstrate the packaging technique using commercially available silicon IGBT and diodes die, and SiC diode die. A thorough characterization of electrical and thermal performance and comparison with conventionally packaged devices shall be performed. Deliverables include power electronic modules utilizing advanced packaging. Contractor shall hold a final review meeting at TACOM near the end of Phase II. PHASE III DUAL USE APPLICATIONS: Power electronic package with improved thermal performance can be expected to find widespread application in compact motor-drive inverters and power converters for Army hybrid-electric vehicles (HE-HMMWV), Navy and Air Force electric actuators and pulsed power systems, commercial laser-diode array packaging, and commercial hybrid electric-vehicles.

KEYWORDS: power modules, thermal management, SiC, silicon carbide, power electronics A02-233 TITLE: Active Hit Avoidance Radar based on Ultra-Low Signature, Time-Modulated, Ultra-Wideband Radar Technology TECHNOLOGY AREAS: Sensors ACQUISITION PROGRAM: PM, Abrams Tank OBJECTIVE: To research and develop a low-cost, ultra-low signature, wide field-of-view, Time-Modulated, Ultra-Wideband Radar for Hit Avoidance applications. This radar must be capable of detecting, tracking, and discriminating incoming projectiles while minimizing detectability and jamability by opposing forces. Also, evaluate possible spin-off of this dual-use technology for Collision Avoidance, Mine Detection and any other applications the contractor finds suitable. DESCRIPTION: Although ultra-wideband radar theory has been around since the 1960s, it was only recently that the enabling technologies have become available. With the advent of ASIC chip technology, pico-second timers, and micro-powered pulsers, Time-Modulated (TM), Ultra-Wideband Radar (UWB-R) based solutions are now feasible. TM-UWB-R differs from, and offers many advantages over, conventional Frequency Modulated (FM), Continuous Wave Radar (CW-R). TM-UWB-R is ultra-low powered (microwatts), stealthy (undetectable), unjammable, causes no co-site interference with other nearby radars or electronic equipment, is immune to multipath conditions, can penetrate foliage and most non-metallic natural & man-made materials/camouflages and can be encased in protective Kevlar armor. Unlike conventional hit avoidance radar systems, UWB-R can be active and protecting at all times without cueing enemy systems of your presence. Although this SBIR focuses on the use of TM-UWB-R for radar imaging, this dual-use technology is also applicable for position tracking and communications. Many commercial as well as government entities are scrambling to employ this revolutionary technology to solve problems that have been challenging using conventional radar solutions. Current TM-UWB-R research includes communications networks on the Space Station (NASA sponsored) and submarines (Navy), position location systems for soldiers and fire fighters (Marine Corp & TDC), through-wall/rubble personnel detection systems (law enforcement & FEMA), gun orientation for military simulations (Army-STRICOM) and through-vegetation terrain mapping system (Army-TARDEC & PM-Grizzly). PHASE I: Conduct feasibility studies to include market research and laboratory-based component evaluations to determine the capability, suitability and risk-level of using current state-of-the-art hardware/software to implement a TM-UWB radar solution for the demanding Hit Avoidance application. Determine the TM-UWB signal processing techniques necessary to detect, track and discriminate various ballistic projectiles. The expected outcome and deliverables from this phase is a TM-UWB Hit Avoidance Radar Feasibility Report and a TM-UWB Hit Avoidance Radar Development Proposal. Feasibility Report will, at minimum, include all feasibility studies, technology risk areas, and demonstration of design feasibility through modeling and simulation, and results of component-level testing. Development Plan will, at a minimum, include project strategy, HW/SW design approach, technical risk assessment, risk mitigation plans, schedule, cost proposal, test plan, and expected system-level performance. In addition, a study of possible spin-off technologies, such as collision avoidance and mine detection, will be conducted and a report provided. Contractor is encouraged to use creative technology and techniques in addressing the Hit Avoidance Radar function to include, but not limited to, the use of Synthetic Aperture, Phased Array, and/or Range Gating Techniques. PHASE II: Proceed with the TM-UWB Hit Avoidance Radar Development Plan, formulated during Phase I. Conduct additional component-level research and development to mitigate system risk. Develop signal-processing code to detect, track, and discriminate targets. Build prototype TM-UWB Hit Avoidance radar system. Test and evaluate capability of the system against representative medium to large caliber ballistic threats. Re-design and refine the system, as necessary, to include additional research and development of hardware and signal-processing techniques. Conduct final test and evaluation against ballistic threats. Conduct research to model, and possibly develop, compatible survivability enhancements (i.e. enhancements which will not degrade the system’s performance) to include, but not limited to, Kevlar enclosures and electromagnetic shielding. Evaluate capability & suitability of technology for dual-use applications identified during Phase I. The expected outcome of this phase is a Technical Report on the Capabilities of a TM-UWB Active Protection Radar and a report on the Capabilities & Suitability of TM-UWB Radar technology for dual-use, spin-off applications. Also, expect a technology risk assessment for feasibility of near and long-term implementation of UWB Hit Avoidance Radar onto Ground Combat Vehicle Systems to include Future Combat Systems (FCS). PHASE III DUAL USE APPLICATIONS: Solicit Program Management (PM) support (i.e., FCS, BCT, Abrams, and Bradley) to fund integration of the TM-UWB Radar technology into the then available Active Protection System Suite(s). Solicit PM and commercial support for developing collision avoidance (CA) systems using this technology. Advantage over current CA systems is that multiple systems in close proximity on the road would not interfere with each other. REFERENCES: Thus far, only two entities have successfully implemented the TM-UWB radar approach. Time Domain, Corp calls their technology Time-Modulated Ultra-Wide Band Radar and Lawrence Livermore Laboratory calls it Micro Impulse Power Radar. Both implementations of the technology are very similar. Time Domain has implemented their TM-UWB technology onto a Radar Test bed, which may be used as a starting point for TM-UWB research and development. This sponsoring government organization has three test beds that the contractor may use during their hardware and software research and evaluation phase.

A02-234 TITLE: Virtual Prototyping Thermal Management Design Tool TECHNOLOGY AREAS: Ground/Sea Vehicles ACQUISITION PROGRAM: PM, Heavy Tactical Vehicles OBJECTIVE: The Army’s next generation of weapon systems and tactical vehicles will be designed with stringent requirements on efficiency, performance, and survivability. To fulfill these requirements under constraints of development time and production cost, the operation of integrated systems must be optimized during the design process. Efficient heat management, versatile propulsion capability, and cost-effective signature control all must be goals of the integrated design effort. This necessitates the development of a design tool that can efficiently optimize the design of these disciplines simultaneously. To meet these ambitious goals, the design tool must aim for integrated system-level design, yet be fully capable of accurately analyzing the details of the cooling system, drive train, signature control, and thermal performance. DESCRIPTION: An innovative solution is required to produce a fast thermal-fluid solver that has the advanced convection capabilities of computational fluid dynamics (CFD) combined with a fast and easy-to-use thermal solver (conduction, radiation, and heat generation). This solver must be tied to accurate models of drive train components, electronic modules, and cooling systems. All component models must predict the heat generated by the components as well as predict their temperature-dependent performance. The CFD solver must be capable of analyzing both free (natural) and forced convection fluid flows, and of modeling the vehicle under both operating and soak conditions. CFD analysis will be performed of cooling loops, engine compartment cooling air, exhaust flow, crew compartment air, and the convection on the outer shell due to both vehicle movement and wind. The design tool must fully consider the effects of the environment, weather, and terrain on both the heat transfer and system performance. PHASE I: Determine the parameters and requirements of the involved systems and models that will affect the advanced fast thermal-fluid solver development. Develop preliminary model for the solver. Integrate the solver into the heat transfer model. Design an intuitive Graphical User Interface (GUI) for rapid problem set-up and optimization of performance criteria. Validate that system–level design is consistent with detailed models of system performance and heat transfer. Results of Phase I will be presented in a report, along with all the data, analysis, and recommendations applicable to Phase II. PHASE II: Generate the model developed in Phase I via a product data management (PDM) system such as Pro/E’s Windchill. Increase the computational speed and optimize the model size through the use of multi-processors and parallelization of the solvers. Develop an optimized system for a heavy duty truck, such as the M1075, manufacture components and validate the system through on vehicle tests. If required, update system and revalidate. Results of Phase II will be presented in a report, including detailed descriptions and results of all testing. PHASE III DUAL USE APPLICATIONS: The design tools and models developed under this SBIR, and the resultant components/systems, if retroffited to existing commercial and military vehicles, or incorporated into new vehicles could be used to enhance their performance and reliability, while reducing fuel consumption and emissions. Additionally, the integration of rapid CFD with thermal design tools will be valuable to many design applications: climate control for commercial vehicles, building ventilation systems, cooling systems, and aircraft.

DESCRIPTION: Recent advances in sensors and micro machine technology, used in MEMS (Micro Electro-Mechanical Systems), allow for new sensors and machines to aid in vehicle diagnostics and prognostics that are vastly smaller in size than sensors used currently. Prognostics work will be executed to monitor the vehicle’s performance continually, instead of being sent to a shop on routine checkups. As an example, problems on vehicles rarely just occur without notice, the performance of a part gradually decreases until the part finally fails. If an engine has a gasket leak in one of the cylinders, it begins small and then gradually gets worse, causing the performance of the engine to decrease. These MEMS (Micro Electro-Mechanical Systems) can act as intelligent sensors, which takes up minimal space and power that can alert the users and maintenance/supply personnel of the problem ahead of time. The proposed technology should include the research and development of multi-task MEMS (Micro Electro-Mechanical Systems) devices that will diagnose problems in the field and perform prognostics on the vehicle’s engine and subsystems. This information provided by the multi-tasked MEMS (Micro Electro-Mechanical Systems) sensors should be integrated onto the vehicle’s data bus, and should interface with the computer control systems and other vehicle intelligence systems. Research shall be conducted on how this retrieved information can be utilized to automate maintenance of the vehicle system. The developed smart systems shall know when components are reaching their life expectancy and implement an accelerated maintenance procedure to shorten service down time. PHASE I: The contractor shall design and develop multi-task MEMS (Micro Electro-Mechanical Systems) sensors to monitor a vehicle’s engine and subsystems and perform prognostic work, and if necessary diagnostic, on those areas. Use these multi-task MEMS (Micro Electro-Mechanical Systems) to demonstrate how prognostic work, and if necessary diagnostic work can be done on vehicles and show how this tool can be useful to maintenance crews. PHASE II: The contractor shall continue the work from Phase I to develop a system that will implement these multi-task MEMS (Micro Electro-Mechanical Systems) sensors developed in Phase I into an actual vehicle and demonstrate its usefulness to logistics and maintenance personnel. Create the user interfaces, data acquisition systems, and communication protocol to integrate the multi-tasked MEMS sensors with. Testing of the sensors on the vehicle should be performed to determine its ability and limits. Testing should include a variety of scenarios that the system may see, such as changing the environment that the vehicle is in to test the way the different sensors react and communicate to the main system. Demonstrate the cost effectiveness of the tool and its performance on diagnosing problems and performing prognostics. PHASE III: A system that incorporates multiple sensing devices and a main communication architecture that can be monitored from a device, which is not located on the vehicle, that monitors the performance of the subsystems of the vehicle could be utilized greatly in commercial and military. This system has great potential to be marketed, which will save the life of parts on these vehicles and make the vehicles safer overall. This system could be environmental, cost, and time effective.
