Abstract:

Values of the lateral stability derivatives sideforce, yaw, damping,rolling moment due to sideslip, and roll amping, derivatives were measured on free-flight models of the Bristol ER. 134 for Mach numbers between 1.2 and 2.6. These show that the aircraft should be aterally stable up to M 2.6, at least, although the free-flight results indicate a somewhat smaller stability margin than estimates or wind-tunnel measurements. Some additional data on lift force derivative and the pitching moment deivative were derived from the longitudinal motion. Author
