NASA Completes Initial Tests On X-66 High-Efficiency Airliner Design
NASA reported last week its X-66 Sustainable Flight Demonstrator (SFD) project has completed its first round of low-speed wind tunnel testing at the Langley Research Center in Hampton, Virginia. The trials collected measurements on lift and drag under multiple aerodynamic configurations and flight conditions. The X-66 concept incorporates an “extra-long” (high aspect ratio) strut-braced transonic […]
