About this award
The Air Force Research Laboratory awarded a $1.44M firm fixed-price definitive contract to Whisper Aero Inc., a small business technology company based in Crossville, Tennessee, to assess the feasibility of an additively manufactured propulsion system wing structure platform. The contract, set aside for total small business participation, runs through September 4, 2026, and represents a continuation of the Air Force's investment in innovative propulsion technologies. Whisper Aero specializes in advanced electric propulsion systems designed for low-noise applications across drone and aircraft platforms, making the company well-positioned to evaluate additive manufacturing's potential in this domain.
This effort aligns with the Air Force Research Laboratory's broader focus on next-generation propulsion and manufacturing technologies. Whisper Aero has established a track record of federal research and development work through multiple Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) awards totaling several million dollars, with prior focus areas including ultra-low noise electric propulsors and multidisciplinary design optimization frameworks. The feasibility assessment will likely inform subsequent development phases and contribute to advancing manufacturing techniques that could reduce weight, improve efficiency, and enhance performance characteristics of propulsion system structures.
