OBJECTIVE: Develop AI assisted defastening robot to improve process time and quality. DESCRIPTION: Various Programmed Depot Maintenance (PDM) processes require removal of fasteners on the aircraft to access behind aircraft skins. The defastening process is currently conducted across all aircraft at Tinker AFB (E-3, E-6, B-52, KC-135, KC-46, and B-1B) by production personnel with hand drills. This amounts to hundreds of thousands of hours spent removing fasteners annually. With the B-1B FIF workload coming to Tinker AFB in FY25, over 10,000 fasteners will need to be removed from each jet. The defastening process is tedious and even the most skilled artisans are subject to fatigue, resulting in reduced quality over long periods of time, as well as increased risk of injury to personnel. Manual drilling is difficult and produces shavings and debris that prove challenging to collect, and drill bits tend to break quickly requiring frequent replacement. As the B-1B workload approaches, there is a concern that removing aircraft skins will become overwhelming to the production line and better methods need to be implemented before the workload arrives. Automating the defastening process will significantly improve personnel quality of life, reduce process time, and drive down risk of rework. Robotics have been implemented in industry to assist the defastening process, but no directly on an aircraft. Other technology, such as E-Drill, has proven successful in improving quality and speed, but still requires artisans to easily access the skins with heavy equipment. 76 AMXG is unique in that the aircraft requirements for this technology is much larger than other ALC's, requiring stricter parameters for space/motion. PHASE I: To meet Phase 1 requirements, proposers should be able to demonstrate an understanding of requirements of fastener removal on aircraft and show feasibility of defastening on aircraft with 50% or more time reduction compaired to manual process and maintain 95% accuracy. Proposer should include a detailed plan for demonstrating this capability on military aircraft. PHASE II: Provide mobile prototype capable of accomplishing Phase I requirements demonstrating ability to reduce flow days on various aircraft with various types of fasteners. Develop integration path to implementation across Maintenance Depots. PHASE III DUAL USE APPLICATIONS: Integrate multiple mobile defastening robots into the PDM process, possibly across different aircraft, with data to prove efficiency/accuracy improvements.
