Title: High-Efficiency Propulsion for EMATT Sprint Speed Capability
Agency: DOD
Contract: N00024-13-P-4025
Award Amount: $79,972.00


Aurora Flight Sciences and the Lockheed Martin Sippican propose to develop a new propulsion system to increase the top speed of an EMATT (Expendable Mobile ASW Training Target) vehicle to 14 knots. Aurora will perform systems-level analysis to determine propulsion system requirements and component-level specifications. Aurora and Lockheed will work with top battery manufacturers to develop a safe, high energy-density battery that provides sufficient power and capacity to meet the sprint speed performance requirements. Aurora will size a high-efficiency motor matched to a novel propeller design which will ensure efficient operation across the range of EMATT operating speeds. Efficiency gains will be realized through the design and optimization of a new fixed-pitch propeller which matches the propeller load to the most economical motor operating conditions. Component-level and total-vehicle performance will be estimated analytically to assess performance and stability. Vehicle safety will be assessed, risk reduction activities and opportunities to improve vehicle performance will be identified, and a Phase II development plan will be identified. In the Phase I Option, Aurora will investigate a hydroelastically tailored propeller to further improve propeller and motor efficiencies across all operating speeds.
