Description

The Department of Defense (DOD) is seeking proposals for the development of high power and torque electric motors for direct-drive rotorcraft applications. The objective is to identify and design an electric motor architecture that can provide high power and torque output at low rotational speeds suitable for rotorcraft applications. The proposed motor should be capable of delivering power in the range of 400-700+ horsepower at rotational speeds of 250-400 RPM, with torque ranging from 5,000-15,000+ ft-lb. The motor should also exhibit high torque densities in both continuous and short-term hover operations. The development of such motors is crucial for the advancement of electric aviation and would have immediate applications in light rotary-wing designs, eVTOL unmanned aircraft systems (UAS), and logistics operations. The project will involve a phased approach, starting with a feasibility analysis and conceptual design in Phase I, followed by detailed design and prototype development in Phase II. Phase III will focus on the integration and testing of the motor in a relevant aerospace application. The project duration is not specified, but the solicitation is open until March 31, 2025. For more information, visit the DOD SBIR 24.4 Annual solicitation notice on grants.gov or the DOD SBIR/STTR Opportunities website.

DOD SBIR 24.4 Annual - Hybrid Electric Powertrain, Power, and Propulsion Systems (HEPPS) Open Topic
Department of Defense
The Department of Defense (DOD) is seeking proposals for the Hybrid Electric Powertrain, Power, and Propulsion Systems (HEPPS) Open Topic. This solicitation aims to bring valuable small business innovations to the Army and expand the relevance of the Army SBIR program to firms that don't typically compete for SBIR awards. The HEPPS Open Topic accepts both Phase I and Direct to Phase II submissions. Phase I proposals can receive up to $250,000 for a 6-month performance period, while Direct to Phase II proposals can receive up to $2,000,000 for a 24-month performance period. The research should focus on HEPPS technologies compatible with various vehicle systems, optimizing fuel economy and performance, facilitating new use cases and tactics, providing an optimized balance for efficient aircraft operation, delivering increased onboard electrical power, and meeting military operational requirements. Phase I submissions require a 5-page technical volume, an 8-slide commercialization plan, and a "Statement of Work" outlining deliverables. Phase II submissions require a 10-page technical volume, a 5-page feasibility documentation, an 8-slide commercialization plan, and a "Statement of Work." Phase II involves producing prototype solutions for edge and austere environments, developing a technology transition and commercialization plan, and evaluating products in a realistic field environment. Phase III focuses on dual-use applications such as reducing greenhouse gas emissions, optimizing fuel economy and performance, improving energy management strategies, and achieving lower weight and longer operating duration. The solicitation is open until March 31, 2025. For more information, visit the [solicitation agency website](https://www.defensesbirsttr.mil/SBIR-STTR/Opportunities/).
