The Department of Defense (DoD) is seeking proposals for the topic "Aircraft Vibration Harvester (AVH)" as part of the SBIR 23.3 BAA. The objective is to develop and manufacture an energy harvesting system for use in airborne applications. The current process of installing instrumentation systems on flight-test aircrafts is time-consuming and requires extensive downtime. The proposed technology aims to generate electrical power near instrumentation sensors, reducing the need for dedicated wiring and minimizing aircraft downtimes. The system must have specific capabilities, including a self-tunable frequency range, output voltage, and power, while complying with Air Force standards and environmental testing. The AVH system should be available for flight testing at least 6 months prior to the end of the project duration. Phase I awards will not be made for this topic, as it is a Direct-to-Phase-II (D2P2) topic. Phase II involves developing and manufacturing the energy harvesting system to withstand airborne environments associated with high-performance military aircraft. The goal is to achieve a Technical Readiness Level (TRL) of 6 based on Air Force standards. In Phase III, the technology can have both military and commercial applications, providing electrical power generation for wireless sensors in airborne applications and harvesting energy in commercial environments such as the auto industry. The solicitation is closed, and more information can be found on the DoD SBIR 23.3 BAA website.
