This paper provides an overview of a bioinspired delay stall propulsor (BDSP) concept that employs delayed stall unsteady lift enhancement to increase the lift on propeller blades without adding any complexity to the propulsor. This BDSP concept can provide greatly increased propeller thrust for a given propeller diameter, leading to both increased speed and/or maneuverability. Alternately, this technology offers reduced radiated noise while maintaining current thrust levels through reduction in both propulsor rotation speed and acoustic cancellation. Preliminary two-dimensional simulations have shown a potential 36% reduction in rotational speed at constant thrust, leading to an estimated 4-dB reduction in the total radiated acoustic power. It is believed that the BDSP concept will be simple to manufacture, rugged, and easy to retrofit into existing marine propulsors. This technology has direct application to torpedoes, unmanned underwater vehicles, maneuvering thrusters, submarines, and other propeller-driven devices.
