An investigation of the two-dimensional flow along flat plates having rounded leading edges has provided additional information on shock-induced separation. The results indicate that laminar boundary layers can sustain the theoretical pressure rise for normal shocks without separating provided that the local Mach numbers are less than about 1.4. The permissible pressure rise across shocks without boundary-layer separation on rounded-leading-edge airfoils having flat sides or convex surfaces was observed to increase with increase in angle of attack and proximity of shock to airfoil leading edge.

An investigation was conducted in the Langley high-speed 7- by 10-foot tunnel to determine the horizontal- and vertical-tail contributions to the static lateral stability of a complete-model swept-wing configuration at high subsonic speeds. The results indicate that, in a general, Mach number effects within the range studied and wing effects on the tail contribution were small and the overall trends of the data of the present investigation agreed with those which have been established at low speeds.
