NASA’s test wing glows pink-purple under pressure-sensitive paint
Hampton, Virginia
At NASA Langley in Hampton, Virginia, engineers coated the Benchmark Supercritical Wing with unsteady pressure-sensitive paint and tested it in the Transonic Dynamics Tunnel. Ultraviolet light made the paint glow pink-purple; high-speed cameras recorded brightness changes tied to airflow pressure. NASA says this was the first use of the technique on a large-scale freely moving model in a low-oxygen environment. The benchmark model is not a specific aircraft, and its measurements help improve computer models.

NASA’s X-59 makes six test flights in one September week
United States
In an October 2 report, NASA said its X-59 completed six flights on September 22, 24 and 25—two per day—beating its previous weekly record by two. The aircraft had logged 38 test flights in total and reached Mach 1.53, above its typical cruise speed of Mach 1.4. The flights expanded the test envelope across speeds, altitudes and maneuvers. NASA planned about three weeks of maintenance and systems review before the next flights; these flights do not establish noise performance.
