An Investigation of Longitudinal Control Characteristics of a Wing-tip Control Surface on a Sweptback Wing at Transonic Speeds by the NACA Wing-flow Method
This is a 1952 NACA technical report by NASA's Technical Reports Server on longitudinal control of a sweptback wing at transonic speeds, aimed at aeronautical engineers and researchers. Its pictures are plain engineering graphs of pitching-moment coefficient against deflection and Mach number, plus a photograph of a small wing-tip control model on a flat base; a designer might take from them only the clean grid-and-curve plotting style and the stark monochrome model photograph.
