The Department of Defense (DOD) is seeking proposals for a research topic titled "Multi-Sensor Prototype for Non-Destructive Corrosion Evaluation and Characterization". The objective is to develop a multi-sensor unmanned aerial vehicle (UAV) system that can assess the condition of a guy wire and identify degradation and potential areas of repair needs before major damage occurs. The current UAVs lack the ability to view below the surface, making it difficult to inspect corrosion on cables. The desired solution is a mobile platform that combines multiple sensors and measurement/analysis technologies to provide subsurface corrosion detection and surface corrosion characterization up to hundreds of feet away from the operator. The project will be conducted in two phases. In Phase I, a concept for the UAV system with a multiple Nondestructive Evaluation (NDE) sensor configuration will be developed and feasibility will be demonstrated. In Phase II, a prototype UAV system will be constructed and the accuracy of corrosion characterization will be assessed. The final phase, Phase III, involves refining the UAV system, demonstrating corrosion identification, characterization, and analysis, and delivering the system to the Navy. The development of this UAV system would enable remote inspections for a variety of commercial infrastructure applications. The project duration is not specified, but interested parties should refer to the solicitation notice for more details. Funding specifics are also not provided.
