Aerodynamic characteristics with fixed and free transition of a modified delta wing in combination with fuselage at high subsonic speeds

From Introduction: "An investigation of the high-speed aerodynamic characteristics of a modified delta wing in combination with a fuselage was conducted in the Langley high-speed 7- by 10-foot tunnel. The model was tested on the sting support system through a Mach number range of 0.40 to 0.90 with both free and fixed transition. Because of the nature of the transition effect, the results seemed to be of the general interest and are presented in the present paper."

Ditching Investigation of a 1/24-Scale Model of the Boeing B-47 Airplane (open access)

Ditching Investigation of a 1/24-Scale Model of the Boeing B-47 Airplane

"An investigation of a 1/24-scale dynamically similar model of the Boeing B-47 airplane was made to determine the ditching characteristics and proper ditching technique for the airplane. Various conditions of damage, landing attitude, flap setting, and speed were investigated. The behavior of the model was determined from visual observations, motion-picture records, and time-history deceleration records. The results of the investigation are presented in table form, photographs, and curves" (p. 1).

Flight Investigation of the Effect of Thickening the Aileron Trailing Edge on Control Effectiveness for Sweptback Tapered Wings Having Sharp-and Round-Nose Sections (open access)

Flight Investigation of the Effect of Thickening the Aileron Trailing Edge on Control Effectiveness for Sweptback Tapered Wings Having Sharp-and Round-Nose Sections

Report discussing an investigation of the rolling effectiveness at transonic and supersonic speeds on a 38.1 degree sweptback tapered wing with NACA 0010-64 airfoil sections and partial-span ailerons of true contour with a modified flt-side blunt trailing-edge shape. The variation of Reynolds number with Mach number and the control effectiveness is provided.

Project C-361 engineers` flow sketch and process description, metal conversion facilities for comment issue

The Metal Conversion Process described herein is designed to handle the combined output of decontaminated uranium from both the Redox and T.B.P. processes. Thus the design rate is 13-1/8 short tons per day. The bulk of the equipment is to be installed in the presently unused 224-U Building. The feed storage tanks, the gas absorber and gas cooler will be outside but adjacent to this building. The process has been divided into two steps: acid recovery and uranyl nitrate concentration; and uranyl nitrate conversion. The major items of equipment and flows thru the plant are shown on Engineers` Flow Sketches, numbered SK-2-50005, and Sk-2-50006.
