High-Performance Computing for Rotorcraft Modeling and Simulation
Dr. Roger C. Strawn
US Army Aviation Development Directorate, AMRDEC Moffett Field, CA
The US Department of Defense has a goal to effectively design and upgrade all its aviation fleet with minimal development cost and risk. One of the biggest risk factors for new designs comes from unexpected aerodynamic and dynamic behavior of the integrated vehicle during initial flight tests. The US Army is tackling this problem head-on by developing new high-fidelity computational fluid dynamics software to identify and remedy potential problems early in the design cycle, well before a prototype vehicle undergoes its first flight test. This talk will describe the Army’s new “Helios” software tool that use high-performance computers to accurately model a variety of complex and multidisciplinary problems in rotary-wing aerodynamics and structural dynamics. These same computational techniques also work for wind turbines and this talk will also show some Helios simulations of wind turbines and wind farms. The talk will also describe the design and implementation of a maintainable and extensible software development framework for the overall effort. A number of university basic research activities have substantially contributed to the success of the Army’s Helios software development and these basic research contributions will be highlighted throughout the presentation.
