Evaluation of Prognostic and Probabilistic Individual Aircraft Tracking (P2IAT): Volume 2- Experimental Loading Sequences

Abstract

A probabilistic fatigue damage tracking method for airframe structure with an inspection criterion of Single Flight Probability of Failure (SFPOF) exceeding 10-7 was compared to the conventional method for fatigue tracking. Two retired fighter aircraft wings were experimentally loaded with different load histories. Fatigue at 14 locations in the outer portion of each wing were tracked with both methods. It was thought that probabilistic tracking would results in fewer inspections because it was believed that SFPOF at inspections with conventional tracking was significantly less than 10-7. Probabilistic fatigue tracking resulted in the same or greater number of inspections as conventional tracking. This volume contains details of the experimental loading sequences for the two wings.
