    Description

    The Department of Defense (DOD) is seeking proposals for their SBIR 24.1 BAA solicitation. The specific topic of the solicitation is "High-Temperature, High-Efficiency Electrical Starter/Generator" and it falls under the Navy branch. The objective of this solicitation is to develop a high-temperature, high-efficiency electrical starter/generator (ES/G) and a system generator control unit (GCU) to optimize heat load, output power, size, and weight of future power systems.

    The Navy is interested in new Electrical Power Generating System (EPGS) technologies that can increase efficiency, specific power, power density, and power capacity for 270 Vdc More-Electric Aircraft (MEA) systems. The EPGS is the main power source for MEA and should provide motoring for main engine start capabilities. The Navy is open to improvements to the existing EPGS or a new novel power generation system architecture/design.

    The desired generator should be able to produce 200 kW of power across a 1.00-to-1.75 speed range, with the higher region of the speed range around 24,000 rpm. It should be capable of providing stable power for continuous and intermittent power across the operating speed range and maintain typical power quality metrics. The offeror should demonstrate feasibility and performance capability during Phase I using modeling, simulation, and analysis.

    Phase I involves defining the generator design approach and developing an implementation plan. Phase II focuses on developing and demonstrating the generator technology that can provide 200 kW of continuous power and can be fitted into the aircraft. Phase III involves packaging and integrating the new generator for use in the aircraft, subjecting it to full qualification testing and flight test profiles.

    The potential impacts of this technology include increased efficiency and power capacity of the ES/G, reduction of system volume and weight, improved thermal performance, better engine and air vehicle performance, and reduced engine heat loads. Industries such as automotive, marine, industrial machinery, agricultural machinery, and construction machinery could also benefit from this technology.

    The solicitation is closed, and more information can be found on the Defense SBIR/STTR website.

    DOD SBIR 24.4 Annual - Atmospheric Water Extraction Plus (AWE+)
    Active
    Department of Defense
    The Department of Defense (DOD) is seeking proposals for the topic "Atmospheric Water Extraction Plus (AWE+)" as part of its SBIR program. The objective of this solicitation is to develop novel atmospheric water extraction technology with potential for energy use below 100Wh electric per liter of water generated across a wide range of environments. The technology should be integrated into a proof-of-concept prototype producing potable water with a clear path to full-size implementation. The DOD has a critical need to reduce water resupply requirements for mobile and self-sufficient operations. The development of AWE+ technology will have important tactical implications, reducing casualties and costs in forward operating environments. The goal is to provide potable water for a range of military needs by developing low-power, distributable systems that can provide water anywhere, anytime, and without the need for any external liquid water source. DARPA, the Defense Advanced Research Projects Agency, is specifically seeking teams with innovative means of releasing water from sorbents which is cyclically stable and has very low energy requirements. The technology should be able to produce water with not more than 100Wh electricity per liter of water produced, and not more than 100Wh thermal energy per liter of water produced. Proposals should outline a plan for reaching these energy metrics and provide an estimate for the range of environmental conditions at which the devices could operate. The project will be conducted in two phases. Phase I is a six-month effort focusing on proof-of-concept material and release mechanism development. Phase II is a 24-month effort with a base period of nine months, followed by two option periods. The performers will be expected to demonstrate functionality of their water capture and release mechanisms in a laboratory environment, producing at least 100mL of potable liquid water over a six-hour period with minimal loss in performance. The ultimate goal of this effort is to demonstrate AWE capable of meeting potable water needs for expeditionary scenarios with extremely high efficiency. Phase III will focus on transition within the DoD/military and further commercialization of the technology. Potential applications include satisfying military expeditionary water needs, reducing logistical footprint and vulnerability of supply lines, and developing next-generation dehumidification systems for residential and commercial HVAC. Keywords: Atmospheric water extraction, atmospheric water capture, atmospheric water harvesting, sorbent materials, advanced manufacturing.
