Description

The Department of Defense (DOD) is seeking proposals for the topic of "Naval Shipboard Embedded Battery Containment System" as part of their SBIR 24.1 BAA solicitation. The objective of this research is to develop a shipboard containment system for embedded lithium batteries that can support large batteries scaling up to the megawatt (MW) and MW-hour (MWh) scales. The containment system should provide protection from shock, vibration, fire, overpressure, and other threats, while also allowing for modular construction to minimize propagation potential.

The research aims to design robust and rugged enclosures that can be easily installed in locations populated by personnel and sensitive equipment. The containment structures should be universally useful and adaptable to various battery designs, without substantially affecting the power and energy density of the storage systems. The proposed enclosure should consider conditions of release, including thermal flux, overpressures, and flame effects, and include a directed ventilation approach for gas release. The design should support devices with voltages up to 1000VDC and power capabilities up to 1MW, with penetrations for cabling and cooling provisions.

The project will be conducted in three phases. Phase I involves advanced modeling and analysis to define the energetic characteristics of cascading battery failure conditions and the development of a conceptual design. Phase II focuses on scaling the enclosure design to relevant size, defining interface points, and building and validating the complete containment equipment. Phase III involves designing and building full-scale flexible rack-mount enclosures for a specific military application, meeting MIL-SPEC requirements, and conducting detailed evaluations and test events.

The successful development of a scalable and cost-effective enclosure scheme will enable the implementation of lighter and more compact energy storage systems on a greater number of platforms and operational equipment. The technology has potential dual-use applications in commercial marine large-scale battery applications. The solicitation is closed, and more information can be found on the DOD SBIR website.

Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic of "Advanced Manufacturing for Common Launch Container" as part of their SBIR 24.4 Annual solicitation. The objective of this topic is to develop applied research towards an innovative capability to use advanced manufacturing and iterative design to enable a Common Launch Container to meet military specification requirements for storage, transportation, and munition launch. The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), and offerors must disclose any proposed use of foreign nationals and their country of origin. The research should address the development of an iterative design process and advanced manufacturing to design and validate a munition container for transportation, storage, and launch. The system should be designed to launch the munition at 12-18 feet per second from the pallet on the cargo ramp or pallet in free flight after cargo drop. The feasibility study in Phase I should investigate all options that meet or exceed the minimum performance parameters specified and recommend the option that best achieves the objective. Phase II involves developing, installing, and demonstrating a prototype system on a SOCOM aircraft. The potential impacts of this research include enabling rapid and iterative manufacturing processes for a broad range of military applications. The advanced manufacturing and modular design will be critical to all services where rapid iteration and production are needed. The system could be selected for production or follow-on iterations for future applications. The project duration is not specified, but the solicitation is open until March 31, 2025.

DOD SBIR 24.4 Annual - Biomaterial Energy Dissipating Structures (BEDS)
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic "Biomaterial Energy Dissipating Structures (BEDS)" as part of the SBIR program. The Defense Advanced Research Projects Agency (DARPA) is specifically interested in developing novel energy-dissipating biomaterial structures to enhance materiel and equipment airdrop capabilities. The current technology, which uses honeycomb cardboard pads, has limitations that can reduce the effectiveness of airdropped equipment. DARPA is looking for new biomaterial structures that can dissipate high levels of energy per unit mass and meet specific performance metrics. The structures must be at least 98wt% wood or other biodegradable plant-based material, have low projected costs for full-scale production, and pass various dynamic crushing stress and rebound energy tests. The project will be conducted in two phases, with Phase I focusing on achieving the specified mechanical properties of the structures within a six-month timeframe. Phase II will involve scale-up and mechanical properties testing, with the option for further scale-up and mass production in Phase II Option I. The ultimate goal is to develop energy-dissipating structures that can be used not only in airdropped materiel protection but also in various commercial applications such as truck trailers, shipping containers, packaging material, and building material for temporary structures. The solicitation is currently open, and the application due date is March 31, 2025.

DOD SBIR 24.4 Annual - YTC Full Load Cooling
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic "YTC Full Load Cooling" as part of their SBIR 24.4 Annual solicitation. The objective of this research is to develop modernized data processing techniques to accurately assess the cooling capabilities of military vehicles with electronically controlled powertrains. The current testing methodologies and data processing techniques for fluid temperature data in critical systems of military vehicles are outdated and cannot be used for assessing vehicles with electronically controlled transmissions. The goal is to modernize the test methodology and utilize synthetic data generation techniques to accurately characterize the performance of the vehicle, even in extreme environments. The Phase I of the project will involve an initial site visit, development of a new Full Load Cooling (FLC) test methodology, characterization of powertrain derating, and submission of a final report. Phase II will focus on refining the FLC test methodology, developing a software program and Graphical User Interface (GUI) for synthetic data generation, and creating a test plan for field conditions. The potential impacts of this research include improved testing and assessment of military vehicles' cooling system performance, better understanding of powertrain derating, and the development of advanced data processing techniques. The research will leverage commercial industry data and expertise on electronically controlled powertrains and can have applications in modeling and simulation capabilities for engine and energy cooling, as well as in the manufacturing process for cooling systems and powertrains. The project duration is from 4QFY24 to 3QFY26, and interested parties can find more information and submit proposals on the DOD SBIR website.
