Flight Measurements With the Douglas D-558-II (BuAero No. 37974) Research Airplane: Static Lateral and Directional Stability Characteristics as Measured in Sideslips at Mach Numbers Up to 0.87

Description: Report presenting flight measurements in sideslips of the static lateral and directional stability characteristics of the Douglas D-558-II airplane. It is part of an investigation to determine the stability and control characteristics and aerodynamic loads acting on the wing and horizontal tail of an airplane from stalling speed up to a maximum Mach number of 0.90. Results regarding variations of rudder, total aileron, elevator control positions and control forces, aileron position, and aerodyn… more

Wind-tunnel investigation at low speed to determine aerodynamic properties of a jettisonable nose section with circular cross section

Description: Report presenting the aerodynamic properties of a model of a jettisonable nose section with a circular cross section as determined at low speed from an investigation in the 20-foot free-spinning tunnel. The results indicated that the aerodynamic characteristics of the nose were greatly affected by proximity to the fuselage. Even for a stabilized nose, it may be necessary to eject the nose forward forcibly in order to prevent high accelerations along the backbone of the pilot.
