    Description

    The Department of Defense (DOD) is seeking proposals for the development of a 100HP electric powerplant that fits into a 6.75" Compact Rapid Attack Weapon (CRAW) afterbody form factor. The objective is to develop a powerplant that delivers performance similar to the existing CRAW propulsion system while integrating with existing interfaces. The CRAW is a lightweight multi-mission torpedo launched from the Virginia Class submarine external countermeasure launchers. The development of a new electric powerplant would reduce cost and maintenance complexity. The powerplant will consist of a primary or secondary battery, an electric motor, and a small form factor motor controller. The entire powerplant system will be contained in a circular tube with specific dimensions. The voltage requirements for the system should be greater than 600Vdc. The overall system weight is restricted to below 90 pounds. Evaluation criteria include battery load testing, Navy testing for abuse and safety, and dynamometer testing for the electric motor and controller performance. The project will be conducted in three phases: Phase I involves developing a concept and feasibility analysis, Phase II focuses on developing and delivering a prototype powerplant system, and Phase III involves transitioning to low rate initial production and coordinating with existing CRAW partners. The powerplant could have applications in other 6.75" devices launched from external countermeasure launchers, as well as unmanned aerial vehicles and electric automobile applications.

    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.
