Pink for pressure
                A one-eighteenth scale model of an Air Force tailless aircraft recently underwent aerodynamic testing in Arnold Engineering Development Center’s four-foot transonic wind tunnel. The test was a technology demonstration entry in which conventional methods and Pressure Sensitive Paint were used to compare the effectiveness of a jet effects spoiler with a solid spoiler in yaw and roll control and stability of the aircraft.
