Understanding and Modeling Vortical Flows to Improve the Technology Readiness Level for Military Aircraft

The charter and goal for Task Group AVT-113 is expressed in its title: "Understanding and Modeling Vortical Flows to Improve the Technology Readiness Level for Military Aircraft". To that end new experiments and complimentary computational solutions were obtained on a simple 65 delta wing model and new computations were obtained on a complete fighter aircraft (F-16XL) for which flight measurements existed. Studying the resulting vortical flows from these two scale- and shape-perspectives together has provided insight and led to an increased understanding of the dominant flow physics which exists on- and off-the-surface, or in- and out-of-the-boundary-layer. Researchers from Belgium, the Czech Republic, France, Germany, Italy, Slovenia, Sweden, The Netherlands, Turkey, the United Kingdom and the United States of America - representing the commitment of air-frame manufacturers, government laboratories and universities - contributed to the work of this task group.
