A wind tunnel nozzle is shaped inside the recently-acquired vertical turning center, or VTC, March 5, 2024, in the Arnold Air Force Base Model and Machine Shop at Arnold AFB, Tenn. The VTC operates similarly to a wood lathe except items are situated vertically on a rotating table within the machine chamber. As the piece rotates, carbide blades within the chamber are used to mill and grind until the piece is formed into the desired shape. The VTC was needed to accelerate the fabrication of various-sized nozzles to be installed in a wind tunnel at Arnold AFB, headquarters of Arnold Engineering Development Complex.
