Shank, right, install pieces of a 7-foot wing model in preparation for testing in the 14-by-22-Foot Subsonic Wind Tunnel at NASA's Langley Research Center in Hampton, Virginia, in May 2025. The lessons learned from this testing will be shared with the public to support advanced air mobility aircraft development.

In May and June, NASA researchers tested a 7-foot wing model in the 14-by-22-Foot Subsonic Wind Tunnel at NASA’s Langley Research Center in Hampton, Virginia. The team collected data on critical propeller-wing interactions over the course of several weeks
