Abstract:

"The objective of this proposal is to develop low noise propellers for application in a UAV concept called SWARM. We propose a combined effort of theoretical and experimental studies to be fully responsive to the need of the SWARM program. AccurateAutomation Corporation (AAC) offers a comprehensive approach to design and manufacture a propeller that reduces the noise by 12dBA with respect to the commercially available propeller for similar thrust requirements. There is an uncompromising need forquiet operation of the UAVs to minimize detection by listening devices. The noise generated by a propeller must be lowered to make it consistent with the remaining components, such as exhaust, of a propulsion system. AAC is uniquely positioned to expandthe propeller design experience gained during the Gun Launched Observation Vehicle program under Navy (NSWC) supervision. As an optional task, we offer to conduct extensive testing and refinement of our propeller. During the follow-on phases, AACproposes to study the acoustic noise suppression due to unsteady pressures generated by propeller blade vibrations. Shunted piezoelectric actuators strategically embedded in the blades will be considered for blade vibration suppression in the Phase II andIII of this program. AAC has an outstanding record in the UAV development arena. We have integrated from propellers to small turbo-jet engines in our UAVs. The quiet propeller is a critical compo
