Full Scale Fatigue Testing The T 38 Fighter Trainer Legacy Wings Ati Symposium 2021

Full Scale Fatigue Testing The T 38 Fighter Trainer Legacy Wings Ati The fatigue testing contributes to the safety case of the t 38 fighter trainer jet remaining in service beyond 2030. this presentation was given at the the aerospace testing. Swri’s jon cutshall describes an swri program involving full scale fatigue testing on the wings of the t 38 talon, a u.s. air force supersonic jet trainer.

Next Phase Of Testing Begins For Usaf T 38 Trainer Replacement Eaa Swri’s jon cutshall describes an swri program involving full scale fatigue testing on the wings of the t 38 talon, a u.s. air force supersonic jet trainer. he gave the talk at the aerospace testing symposium in september 2021. Major efforts are underway at nal to design, fabricate and set up a multiactuator electrohydraulic computer controlled full scale fatigue testing facility for fighter aircraft. The paper examines the adequacy of the u. s. air force damage tolerance inspection criterion for protecting the safety of the flight of an aging military trainer aircraft. At present, engineers are conducting life analyses and full scale testing on t 38 wings in a facility at swri’s headquarters and life analyses of the a 10 on site at the ogden alc.

One of the requirements to certify any military or commercial transport aircraft is a full scale fatigue test. the goal is to evaluate the durability of the airframe under conditions that are as close as practically possible to those that will eventually restrict its service life by fatigue damage. T 38s were designed for 7,000 flying hours but many have surpassed 20,000 hours, requiring life extension to bridge the gap to replacement by the t 7a. pacer classic iii is the type’s third structural renewal effort and the most intensive in its history. The t 38's wings were originally designed to withstand 7.33 g loads and for a fatigue life of 4,000 flight hours. this proved sufficient for the majority of the training syllabus, but was a major limiting factor when the aircraft was used for aggressive dogfighting style maneuvering. A verification method for the fatigue life of the jet trainer wing with integrated fuel tanks is presented. the test was performed to identify the critical points of the structure, to determine strain data and to proof fatigue life of the wing.
