On Sept. 30, 2024, General Atomics Aeronautical Systems, Inc. (GA-ASI) completed a major milestone with the full-scale fatigue testing of an MQ-9B Remotely Piloted Aircraft (RPA). The team completed the “second lifetime” of fatigue testing, which is equivalent to 80,000 operating hours and represents an important step in validating the design of the airframe system.&nbsp;The testing is part of the aircraft certification to NATO standard STANAG 4671, where the aircraft will ultimately be tested through three lifetimes, thereby proving the 40,000-hour lifetime of the airframe.The full-scale fatigue test simulates the aircraft’s design service through the application of repeated structural loading on the assembled airframe. The testing identifies any potential structural deficiencies ahead of fleet usage and assists in developing inspection and maintenance schedules for the airframe. The results of the test will be used as part of the documentation for certification and will form the basis for in-service inspections of structural components.MQ-9B is GA-ASI’s most advanced RPA and includes the SkyGuardian® and SeaGuardian® models as well as the new Protector RG Mk1 that is currently being delivered to the United Kingdom Royal Air Force (RAF).“Full-scale fatigue testing is an integral part of validating the airframe design and a key input for the certification of the airframe prior to entering service,” said Chris Dusseault, vice president of MQ-9B in Europe. “The completion of the fatigue test builds confidence for our MQ-9B customers that the SkyGuardian/SeaGuardian meets the stringent design rigor and is mature at Entry into Service.”The testing is the validation of years of design and analysis efforts. This is the second of three lifetimes of testing for the airframe. Two of the lifetimes simulate the operation of an aircraft under normal conditions, and the third has intentional damage inflicted on the airframe’s critical components to demonstrate its resistance to operational damage that may occur over the lifetime of the air vehicle.Testing was conducted from Jan. 31, 2024, through Sept. 30, 2024, at Wichita State University’s National Institute for Aviation Research in Wichita, Kansas. The airframe tested is a production airframe purpose-built to support the test campaign.In addition to the RAF, contracts have been signed for MQ-9B with Belgium, Canada, Japan, Taiwan and the U.S. Air Force in support of the Special Operations Command.
