Force and Longitudinal Control Characteristics of a 1/16-Scale Model of the Bell XS-1 Transonic Research Airplane at High Mach Numbers

Abstract

Tests show large drag coefficient beyond 0.78 Mach number. At 0.1 lift coefficient and 0.9 Mach number, drag coefficient increases three times subcritical value. At 0.825 Mach number initial lift force break occurs, although not severe up to 0.875 Mach number and elevator control decreases. At 0.9 Mach number stabilizer must be used as trim control decreases. At 0.9 Mach number stabilizer must be used as trim control because of elevator control loss and reversal. Stabilizer control, effective to 0.93 Mach number, requires rapid and accurate manipulation beyond 0.90 Mach number. Tests were to be continued.
