"The rotating multicylinder method for in-flight determination of liquid-water content, droplet size, and droplet-size distribution in icing clouds is described. The theory of operation, the apparatus required, the technique of obtaining data in flight, and detailed methods of calculating the results, including necessary charts and tables, are presented" (p. 1).

Memorandum presenting tests made on a normal-shock inlet mounted as a scoop on a flat plate on which a turbulent boundary layer was generated. A boundary-layer-removal scoop was provided between the inlet and the plate and various amounts of the boundary layer were removed. Results regarding the main inlet, boundary-layer scoop, and an evaluation of results are provided.

Report presenting flight testing with two jet-propelled airplanes in rough air to investigate effects of sweep on gust loads and gust selectivity. Data was taken with an unswept-wing airplane and a 35 degree swept-wing airplane for incremental accelerations corresponding to airspeeds of 300 and 450 miles per hour. The results indicated that the swept-wing airplane experienced lower loads in turbulent air than the unswept-wing airplane.

Report presenting measurements of chordwise pressure distributions at four spanwise stations over a 10-percent-thick wing of the Bell X-1 airplane. Results regarding pressure distributions at the various stations and section aerodynamic characteristics are presented. The data was obtained for a range of Mach numbers from 0.30 to 11.9 and altitudes from 17,000 to 47,000 with several different types of maneuvers.

Report presenting an investigation of the flow behind the lifting surfaces of a model equipped with a 60 degree triangular wing and a 60 degree triangular canard tail. Results regarding the force and moment data, air-stream surveys behind the wing, effective values of downwash and dynamic-pressure ratio, effect of tail height and length, a comparison with previous data, the effects of component area and ratio, and the effect of a canard tail are provided.

From Introduction: "This paper will treat the problem in the suggested manner, beginning with the development of a suitable boundary condition to represent mathematically a homogeneous boundary which has the same flow characteristics, at a point in the flow sufficiently removed from the boundary as the actual physical boundary of alternate open and closed portions of the wall. Numerical results will be presented for circular tunnels with uniformly distributed around the circumference, for rectangular tunnels with uniformly distributed around the circumference, for rectangular tunnels with uniformly distributed slots in the top and bottom walls, for rectangular tunnels with the slot distribution determined by a transformation from a uniformly slotted circular tunnel, and for a two-dimensional tunnel. The results of this paper are derived on the basis of an incompressible potential flow."
