Contract: N00014-13-P-1098
Award Amount: $80,000.00


Cornerstone Research Group Inc.'s (CRG) demonstrated expertise in the proposed technology presents the Navy with the opportunity to obtain an electric tail rotor drive system for implementation on existing naval helicopters. The proposing team's track record of innovation in electric propulsion positions CRG for successful implementation of a hybrid electric tail rotor drive meeting the Navy's operational needs. CRG proposes to develop a hybrid electric tail rotor drive system for naval helicopters that will lead to redundancy advantages, decreased maintenance cost, greater flight deck safety, reduced noise, and higher system efficiency. CRG envisions a complete electric drive system consisting of a generator fed by the main transmission which supplies power to a high-efficiency electric motor mounted directly at the tail rotor. The electric motor will be capable of functioning over a range of speeds and could have the ability to pivot in flight providing greater operational flexibility.
