Researchers Awarded $1 Million to Develop Better Models for Rotor Spar Fatigue
The University of Texas at Arlington and the UTA Research Institute (UTARI) will develop state-of-the-art computational methodologies to predict the strength and life of rotor blade assemblies, known as rotor spars, through a new $1 million agreement. The NASA project is funded through the federal agency’s Aeronautics Research Mission Directorate in alignment with the Advanced Composites Project, which focuses on providing safe and sustainable U.S. and global aviation. Researchers also are working to reduce the timeline for development and certification of state-of-the-art composite materials and structures, which will help make advanced composite components more competitive in commercial aircraft.
The three-year project, called “Development of Fatigue Life Prediction of Rotor Spars by Using Discrete Damage Modeling”, will be lead by Endel Iarve, an accomplished research scientist and expert in composite...
