Abstract: This proposal addresses the opportunity to develop an optimized power and data bus for aircraft rotor loads monitoring by offering an innovative solution that delivers high power density energy harvesting and reliable delivery of large volumes of data from a rotating frame to a fixed frame. The system non-intrusively harvests energy from the main rotor and wirelessly communicates loads data to a HUMS data aggregator. This innovative development work will be completed through collaboration between KCF Technologies and its partners. This partnership provides a high degree of capability in helicopter wireless communication, energy harvesting, and fiber optic strain sensors.
Benefits: This proposed solution benefits the Navy by enabling the use of new technologies that reduce maintenance cost and down time, and improving safety. KCF's development approach offers low technical risk and rapid commercialization through leveraging COTS hardware and extensive experience in wireless and energy harvester technologies. The technical merits of this proposed solution include lightweight, trustworthy wireless communication, minimal modification to the aircraft, and high reliability. The proposed technical solution is flexible in that it can be applied to a wide range of helicopter platforms including non-military helicopters. This sensor system will serve as a key building block for extending the benefits of HUMS into the rotor assembly.
