The Effects of Sweepback on Longitudinal Characteristics of a 1/30-scale Semispan Model of the Bell X-5 Airplane as Determined from NACA Wing-flow Tests at Transonic Speeds

Joseph J. Kolnick, Robert M. Kennedy

Abstract

Report presenting tests using the NACA wing-flow method to determine the effect of sweepback angle on the longitudinal characteristics of a scale semispan model of the Bell X-5 variable-sweep airplane at a range of Mach numbers. Lift, drag, and pitching moments were obtained for a range of angles of attack.
