Rocket-Model Investigation of Lateral Stability Characteristics and Power Effects of a Jet-Engine Airplane Configuration with Tail Boom at Mach Numbers from 1.15 to 1.37

Results from a limited research program initiated to study the effects of a hot propulsive jet on the lateral stability characteristics of a fighter-type airplane configuration are presented. The data were obtained on a rocket-boosted free-flight model and a Mach number range from 1.15 to 1.37 was covered. The configuration tested had sweptback-wing and tail surfaces and a tail boom of rectangular cross section. A solid-propellant rocket motor was used to simulate a turbojet engine with afterburner operating. Pulse rockets provided yaw disturbances during both power-on and power-off flight.
